  • In this video I make a simple silicone from sodium silicate and ethanol. The sodium silicate was purchased for this video, but can be easily obtained by dissolving silicon dioxide in sodium hydroxide.
    This is my first real foray into polymer chemistry, and as you chemists know, this is about the simplest possible example. I started so simply because I'm unsure whether there is any real interest in polymers, and I'm more than happy to try something more complex if there's any interest.
    Just let me know!

    In our childhood we had bouncy balls called Flummi, which never made any sense to me: too hard to play with it indoors (they are able to smash every glass into pieces easily) and too bouncy to play with it outdoors (they always bounced away to places where we never found them again...).

    Had to try this out - but the mixture was way too brittle (just like coarse wet sand) to form a ball from it... 🙁
    At first I had the impression that the silicate was simply precipitated rather than polymerized.
    But then the texture and name seemed very familiar to me: Dimethylsiloxane is a defoamer that is used against flatulence.
    The crumbly substance felt the same between my fingers as the tablets in my mouth when chewed.
    Of course, I would strongly advise against making your own medication. Here unreacted silicate can lead to life-threatening complications in the digestive tract. But I couldn't figure out how to make a bouncing ball out of it instead when I copied it.🤷‍♂️

      I did a good deal more research over the last week and I'm fairly confident the mechanism from the literature I posted in the video is wrong. My best guess at this point is that it is cross-linking, but the cross-links are Si-O-Si with sodium ethoxide acting as a leaving group. However, that's just what makes the most sense to me. I've seen tons of other totally plausible ideas thrown around here in the comments. I do think the wet sand analogy is pretty accurate too, and I think I downplayed just how much persistence you really need to force that crap into a ball. It does work eventually though!

    On the 'slow to cure' caulks, It can be fun to play with these. The acetoxy cure silicone cures by releasing acetic acid and absorbing water from the environment. If you mix rapidly with various damp alkali, you get interesting behaviour, from simply setting rapidly, to making a foam if you use a bicarbonate salt.

      Yeah I think the mechanism from my source is wrong.

Best I have for now, but a lot of comments have proposed many other ideas that also may be correct.. Honestly the lack of bubbling should have been a giveaway that no oxygen was produced, guess I just got too excited someone else did the mechanism for me lol.

    Sodium metasilicate (crystalline Na2SiO3) isn't usually sold to regular customers as it is because it's corrosive. If you bought your waterglass at a hardware store, it probably is an amorphous silicate variant much more rich in silica which is safer to handle. It is also good for making bouncy balls, though. When I was in middle school I used to make them all the time from silica-rich waterglass and denaturated alcohol. Now I wonder what happens if I use metasilicate.

      hey buddy as have mentioned that you are a newbie to the chemistry land! I have some suggestion books along with videos.
      The first step is you have to understand what is chemistry and what is not, get used to its language and how to perform stoichiometric calculations.
      For this I can suggest you to either study the Mortimer or Silberberg general chemistry books. You can read the book in your native language or English edition. This is optional due to which language do you prefer.
      The second step is really wide and covers many branches like Organic chemistry, Inorganic chemistry, Analytical chemistry, Physical chemistry etc.
      you can study on these branches but remember that this is not meaning that you can cover every topic. Choose which one you want and which one do you like.
      The third step also exists but it is based on academical research in or out of the university as PhD or post doc.
      For example most of the UA-cam dudes do Organic chemistry. Like Apoptosis.
      For the videos I know a few channels covering chemistry :
      Nile Red [Mostly Organic chemistry]
      NurdRage [Amateur available methods and experiments chemistry, Inorganic and some time Analytical chemistry]
      Thy Lab, Lab coats [Both are mostly organic but second covers some cool physics stuff]
      The periodic videos [Covers almost whole periodic table elements explanation + some other cool explanation]
      Apoptosis !!!!

      Strong alkalis just dissolve silicon dioxide creating silicates. Molten NaOH easily dissolves glass and concentrated NaOH solutions can dissolve regular sand under high pressure. If silica is in the form of silica gel it is even easier, you can easily dissolve silica gel cat litter in concentrated sodium hydroxide solution. It's an acid-base reaction, silicon dioxide is a very weak acidic oxide.

    I just went down a bit of a rabbit hole on the subject of silicone's environmental impact. It's a mixed bag, but not an unmanageable one the way plastic is. It generally breaks down even slower than plastics (I'm sure there are exceptions due to how varied both can be), but that can be a positive for reusable items. It's terrible for disposable items, but ffs we gotta stop with that anyway. But at EOL, it can generally be incinerated safely, unlike plastic, since it mostly produces sand, carbon oxides and water, unlike all of the plasticizers and softeners and adjuncts added to make most plastics useful. Sure, produces carbon dioxide and monoxide, but compared to plastics... Not that it create much energy when incinerated, but the toxic outgassing is less.
    In a future without plastics, maybe we'd use more silicone and have a collection system for it so it goes into incinerators instead of landfills? Or maybe we'd find a recycling system that uses it as a relatively clean source of silica for glassmaking or more silicone?

    • @SianaGearz

      Plasticisers are a misconception, most plastics you use day to day do not rely on them or don't use any, and in turn with a couple exceptions they can be incinerated completely. PP PE PS PET are the bulk of the plastics used and they can be incinerated completely. There are other trouble additives though, like halogen based fire retardants necessarily used in most PS items and also PVC the polymer per se that's a troublesome one.

    I don't think your explanation and the reaction given are true.
    First, any crosslinking would require a molecule with at least two functional groups, and ethanol has only one.
    Second, your reaction has oxygen as a product. Ask yourself - is really any gas produced? Keep in mind that the stoichiometry you've provided dictates that for each mole of ethanol reacting (ca. 50 ml) you'd get over 20 liters of oxygen. That's quite an off-gas, I'd say.
