The benzene synthesis from sodium benzoate shows that (II) salts are not actually necessary, I used in this reactions always sodium benzoate and made
an iron salt from the acetic or propionic acid and from all of this I made a slurry. But I added coarse steelwool and lots of it as the problem is
heattransfer in special with calcium salts which make a solid rock. The steelwool transfers the heat insides and cracks the salts so the product can
get out. And don't heat at the bottom only but the sides too. gas-burner and a tent for the hot air to go up along the sides of the vessel.
Glassware is much too precious for this. I used old solvent cans and just threw them out after the reaction.
I feel there is a lot of over-thinking going on here.
PS: Rubber is crap, but if you use silicone rubber and wrap it in thick (0,2 mm) PTFE tape..... Helps your cork a lot too....
