Very interesting! I'm planning to try this reaction and was wondering if paraldehyde could work as a synthetic equivalent to acetaldehyde? It seems like a safer option to handle than the monomer. Thanks!
Very nice! I synthesized p-Methoxy-Cinnamic Acid from Benzaldehyde via Knoevenagel reaction as part of my undergraduate organic chemistry lab course - I'm specialising in inorganic chemistry, but that synthesis was one of my favourites. This one seems more challenging, at least for getting a good yield, but still very interesting to see!
Thank you, brother, but I want you to have the necessary ingredients. I want the ingredients to make a kilo of Bakelite. How much phenol, formaldehyde and hydrochloric acid should I put?
Usually, I clean everything with soap and water, then with acetone and at the end with air or just letting it sit over night, before I use it again for the next distillation.
Yes, it's a general procedure. As long as there are no other functional groups, the Aldehyde and CH-acidic compound can be substituted by anything and it's highly likely to work.
Sir Can you please make a synthesis of di iodomethane? It is the heaviest organic solvent and it can float an piece of aluminum I think that's why I really like it
Complex synthesis, since it's a challenge to separate benzaldehyde, acetaldehyde and cinnamaldehyde, and they are easily undergo oxidation, the yield was so so, 23%

Nice to see you are back making some videos ^^
You just saved me so much work for my chem assignment
Thank you!!

great to see that you're back!

10:08 do you reuse the same cooking oil for other distillations?
I've been using this for about 10 years now. :)
Nice job! Glad U R with us. Keep on!
P.S. Could you please provide a reference to the original synthesis? That would be very helpful.
Thanks! Unfortunately, the procedure is from a german book called "Organikum" by Heinz Becker. And there's no translation :/
@@RaExpIn Ich brauche keine Übersetzung 😉. Dieses Buch ist mir bekannt. Tolles Ding. Danke dir und viel Erfolg und Spaß bei deinen Experimenten!
Achso :D Es müsste S.521 sein.
@@RaExpIn Danke! 🙂
Gern geschehen! :)
Is a new apparatus swapped or cleaned before the final product? How do you avoid contamination from the previous distillation.
Usually, I clean everything with soap and water, then with acetone and at the end with air or just letting it sit over night, before I use it again for the next distillation.
I recommend using sulfuric acid as the high temperature bath filler. It is horrible to clean the glassware from cooked oil
Hot sulphuric acid is extremely dangerous ..I'd sooner clean dirty glassware than risk that.
@@antejl7925 I've proposed an alternative to oil. I've never had problems with sulfuric acid bath, btw
Is it possible use Salicylaldehyde instead of benzaldehyde?
Yes, it's a general procedure. As long as there are no other functional groups, the Aldehyde and CH-acidic compound can be substituted by anything and it's highly likely to work.
The yield could be increased by adding acetaldehyde in parts to a solution of benzaldehyde and alkali.

Do aldol condensation of acetone pls
I made a video about dibezalacetone. Or do you mean to react acetone with itself?
Have you considered using milder catalysts? Like primary amines?
It was a general procedure. So, I didn't think about it. Would be worth a try. According to Wiki the yield should be at around 60%.
Complex synthesis, since it's a challenge to separate benzaldehyde, acetaldehyde and cinnamaldehyde, and they are easily undergo oxidation, the yield was so so, 23%
that residue tho 🥴 could be cool to try to work it up, might be a mixture of benzoic and cinnamic acid 😊
I actually did a few tests on it. As for example reacting it with sodium hydroxide and acid afterwards to precipitate it out.
Nice
If you're gonna use chemdraw, please use a common style like ACS1996
I'm using Chemsketch, because I don't have a license for ChemDraw anymore. I will have a look at it.
What u r planning to do with this crude cinnamaldehyde???
Pattiserie flavours?
ok
