>> I have repeatedly seen an attempt to acylate toluene with propionic acid in polyphosphoric acid. And even with allocated exits.
Any details? It looks interesting. I'm not a chemist, but if there's a proven technique, I might want to try it.
>> The only problem there is that you need to warm the light boiling
An autoclave is easy. The only question is how much pressure.

Bag under the autoclave is also not very difficult, if you do not need strong stable seals.

Toluene is now easier to get benzene. Only he'll be technical. It is inexpensive, you can wash, overtake and will be normal probably.
Are there any other ways to get rid of propion? I'm sure there are. Just its synthesis from sodium propionate against the background of everything else looks temptingly simple.

5 times more expensive. Also, the range of previews on the sites is extremely scarce.
