The best base oil - Alkylated Naphthalene
Вставка
- Опубліковано 28 чер 2024
- Most people tend to think that polyalphaolefins are the top of the tree when it comes to base oils. But PAOs are so non-polar that they often encounter issues with additive solvency and varnish deposition, which necessitates a co-basestock in finished lubricants.
Esters on the other hand, are so polar that they suffer from hydrolytic instability, are hygroscopic, and sometimes out-compete lubricant additives at metal surfaces.
Alkylated Napthalenes are the "third way" lubricant - the best of both worlds. - Наука та технологія

I forgot to mention, they're also food safe, kosher and halal!!! The base oil itself is NSF HX-1 certified.
The kosher and halal part had me laughing hard!!! xD
So I could spray it on toast and survive?
@@nunyabusiness3786 Very very very thinly, hahaha.
Just came across your channel today. Great stuff! I used to be involved manufacturing AN, Esters and PAO's for a large oil company during the glory days of group 4 and 5 usage in engine oils. From an operations point, pure naphthalene is very difficult to handle, especially in colder weather. And as it's a batch operation like esters (PAO is continuous) it's more expensive to make by a significant margin than PAO. You're correct that putting the alykl group on different points of the ring yields different properties. Reactionwise, the hardest part is to get the alkyl group to hitch itself consistently to the same spot on the rings. We had to develop a proprietary catalyst to accomplish this.
Great insight! With over 20 years around ANs, you identify probably the main reason why there are only two players in the market. It's hard to make them consistently and cost-effectively.
Of the two players in the market, one had already developed its downstream range before they decided to sell ANs. So, their R&D had almost all been completed & the downstream products were generating cash. As a result of the downstream product range, they can sell a wide range of ANs.
The other (with whom I suspect you worked) had the resources to develop the two grades most likely to have a broad range of applications. The barrier to entry by either route is very high.
Absolutely love this chemistry lesson
LE. Hats off to you. You are putting genuine efforts make concepts so simple to understand. Thanks lot
Thanks Ganesh!
@@LubricationExplained Thanks for your video! Do you know whether naphthalene based oils are used in significant amounts as lubrciation in machines that are used for manufacturing other products? I couldnt find any data on it. There is some anecdotal info about products containing naphthalene and nobody knows why. Some years back Kelloggs had to recall some cereal and occasionally there's naphthalene in carseats for children or toothbrushes.
One of my favs as well, had some solubility issues with a custom full PAO Diesel engine oil I made. A bit of Alkyl-Naph and a few other bits really helped.
Oooooo. Custom DEO? Do tell!
Here in Germany the top oils from Ravenol, specially the racing oils, use to have AN on the formulation. Best Regards
Thanks for sharing! That makes a lot of sense.
U forgot Redline , Extreme Amg ( Produced by Venol in Germany) and Amsoil Signature Series
Now their high end oils are 100% PAO+Ester right
That was excellent. I appreciate your level of detail. You’re a good teacher.
Only the part of the viscosity index which is very low, so it is very important to formulate mixed Technologies that helps to maintain good VI
The thumbnail, the title, the three views (as of my seeing it)... it's marvellous 😀
Nulon oil state that their Race engine oil is PAO Alk Nap, while Penrite state theirs is PAO ester. They dont say much beyond that. Penrite has little information on their oil blend and Nulon even less in specifications and data sheets. Thanks for the video.
Thanks! Yeah, most of the oil companies are loathe to reveal much about the formulation which is a real shame.
I think there could be problems with seals, especially Buna N. Steric hindrance could prevent the naphthenic from migrating into the rubber, but the R groups would still allow Buna N process oils, additives, etc. to migrate out. The seal would therefore shrink. This is why you never have a Pure Buna N formula. A non-oil resistant rubber is always in the formula so it can swell to compensate for the shrink of the Buna N which is oil resistant.
?You're right, and it has probably been an achille's heel for some product developments. However, you also have to remember that one player makes ANs with branched alkyl chains, while the other uses predominantly straight chains. Success may be possible by using the nearest product from the other player and/or moving to a lower viscosity AN, which usually means less substitution, so less steric bulk. Or back out some AN and add a little ester. Not a simple task, I agree. But it's why formulators are skilled people.
I really like your Video
i watched your video talking about base oils
In your opinion, in the production of insulating oil, which is the better naphthenic and paraffinic base oils?
Great explanation of the chemistry, this was super helpful. One question, at one point you mention carbon double bonds are weaker than single bonds, but then later on you say they're less stable? In what cases are they stronger or more stable vs weaker or less stable? Thanks!
I am so grateful if u make a video about sulphur in engine oil what additive did they use n how sulphur can harm the engine oil n harm the engine components???..please..thank you😅👍😁
There's a video on the channel which is "Zinc in Engine Oils". There's also another called "EP additives". Both of these should cover what you're looking for!

@@LubricationExplained thanks a lot..sory i ask to much..i am just started to learn about lubricants..this is very helpful..i love your channel..keep it up @lubrication explained..👍😊
What do you think about high viscosity AN’s such as AN having vis@40C of 300 cSt ? Its aniline point is 125. Do you think it can still be used as solubilizer? I have heard that this grade might worsen the shear stability if we combine with PAO to formulate a synthetic automotive gear oil like 75w-90. Thanks in advance for your comments :)
Good ol' LE, Thrashes it out... Rings the bells...
I would disagree at one aspect - An oil, mainly based on Ester or AN, would be specific, racing oil, application?
They're expensive. Also, Don't want to change oil seals, too often, in real life...
For practical use: PAO + AN as a polarized, hydro stable, additive "solvent" , would be nice? (eg: Mobil?)
Cost effective "solution" = GIII, kinda uniform molecules, a bit polar? A bit less AN, with additives? :)
Pl do a show, on how Esters or AN's swell seals & Explain the difference between seal swelling & pliability?
As far as engine oils go, yes, you'll probably never see a pure AN engine oil mainly because of its low VI. The only times I've seen AN oils are in industrial applications where you don't need performance over a wide temperature range, because most equipment operates at constant temperature for 99% of its life.
In the engine oil world, you're right, it's most likely going to show up as a co-base with a PAO.
Can you mention engine oil brands that contains Alkylated Naphthalene ?
I haven't really kept up with the engine oil formulations to be honest. As mentioned below, AN has a lower VI than parrafinics so it's not going to be the main base oil in an engine oil formulation, it's more a co-base that can replace esters in engine oils.
@@LubricationExplained You are correct. I have been told, that "mobil 1 annual protection" use to have small quantities of AN.
Ravenol,Extreme amg( Produced by venol) , Redline From Usa and Amsoil.✅💪
All Mobil 1 EP + Annual P.
Can it be used for grease formulation instead of Napthenic Base oil, will it be better? As you explained better solvency of additives.
Do some digging on Schaeffers oil. I bet my life savings that it’s the best oil for the market. But their base oil is not very easy to find info on.
Tried digging a little over the last few days and you're right - info is pretty thin on the ground.
@@LubricationExplained Which is just how they want it. Companies that sell lubricants don't want customers to be educated about how they really work and what constitutes a quality product for a certain application. They all benefit collectively from ignorance and they can sell their product without legal liability.
@@nunyabusiness3786 what you just describe sounds very much like modern politics just had to add 👍
Hello. What is the best types of oil for seals? And the worst ones? Thank you.
What do You think of Tungsten Disulfide as a oil additive? If it's as good as I have been told, than why hasn't it been used in engine oils.
When the oil label has one of the ingredients as" mono-c20-24-branched alkyl derivs " is this a form of alkylated naphthalene ??
Good question - I'm inclined to say no, as this description is pretty common to detergents (comprises the long hydrocarbon chain of the detergent). From memory the ANs I've seen are C12-16 branches.
This is Alkylated benzene
Where can I buy products made of this?
Good question. It's really difficult to know where this is in use, as companies don't typically disclose formulations where they don't have to.
if you knew wat oil is based with an ? best regards your sibscriber
Can anyone tell me if Moly is a good lubricant for my engine oil? Not the company but the actual powder. Thanks.
Moly is good for engine by reducing friction but would recommend you use engine oil which contains higher concentration of Moly. Engine will running smoother.
Is Heavy alkyl benzene a type of Alkylated napthalene..?
They’re a separate class of lubricant.
Did alkylated naphthalene have sulphur in it????
sulfur is an additive common in anti-wear packages
@@mytech6779 yes that true..but i talk about sulfur in base oil..
@@kahar_diy3955 Sulfur in base oil acts as a mild antioxidant. It is only removed as a side effect of the hydrocracking process for group 2 and group 3. Both natural sulfur and additives can in some conditions react badly with copper based metals, this is why some manual transmissions require GL-4 oil while the hypoid differential can use GL-5, the GL-5 has better anti-scuff protection but it can damage bronze in certain operating conditions.
@@mytech6779 owh..i see..thanks for the great info..but i have another question if i may ask..😅
how long the sulfur additives can lasts in engine oil..?
N after that did some of sulfur level 0.03% remain in base oil group II n III can reacts n harm hydrogen n carbon molecule the has form in hydrocracked process?
Generally no. As it's a pure synthetic base oil - i.e. synthesised from known feedstocks, sulphur levels are vanishingly small.
Naphthenic base oils (which are refined from naphthenic crude oil) will contain sulphur levels similar to other Group I, II, and III mineral oils, but that's a different base oil technology entirely, despite similarities in the name and ring structures.
As @MyTech points out though, there's likely to be sulphur in the antiwear additives. Both ZDDP and MoDTC contain sulphur, as examples.
Pao + ester is it good stuff?
100% it is
what gear oils you seen with this?
It's actually a Mobil industrial circulating oil that was discontinued just over a year ago. Real shame, I thought it had a lot of potential.
Best base oil? Viscosity Index is too low.
Granted - it's not going to be the main base oil for automotive and mobile equipment. But a lot of industrial equipment spends 99.9% of operating time at a very narrow temperature window - for these applications VI isn't really all that important. Like I said in the video, all base oils have their place - I just used "best" in the title because I'm experimenting with how UA-cam treats titles in the algorithm.
@@LubricationExplained Understood.
@@LubricationExplained It definitely got me interested
RedLine,Ravenol,Extreme Amg ( russian oil and also produced in germany) and amsoil signature series are the tops today . Rest is 💩
polyolefins have poor lubrication.
