and i could you also have told you this back then as this is really not new to me ;D
a quick google said me the pyrolysis of benzoic acid begins to take place at 370°C so yes it would definitely, think its a lot more a matter of not getting it to burned down to coal ;D
you should look into the other document, there are plenty that are better, some especially for that purpose designed *points at the 2nds documents writer org*,
I found it also very interesting, one could also make benzamide with such an apparatus or with an acid-inert metal a good device for dietherproduction... then it hit me, org already told me to do that months ago, damned.

Hell yeah,Carl!!!  I wish you'd have posted that pic a year ago.  Woulda saved afoaf from having to weld an SS distillation still for dry distillations.  He is much happier with it, but this woulda saved a ton of time.  Luckily, weldin is fun. 

The cookie tin is THE most ghetto fabulous shit I have seen in a whole minute.  Even beats the SS canteen I have seen used for the same thing.  I love it!!!  Wonder if it'd stand up to dry distillation of PAA and lead acetate?  Hmmmmm
I used solvent tins for the benzene and for experiments regarding PAA/lead/iron and this.
I used them only for one reaction and then used a new one, and I think thats the better this way.

What I found out is that the problem odf this kind of reaction is the heat-transfer through the mass in the tin and I added coarse steelwool  what solved the problem.

This guarantees decent yields without having to vent some very hot inert gas through the reaction whats quite demanding.
Other stuff like steel scrap was used on other occasions with good results.
There are many ways to implement this as soon one has recognized the problem behind.

Many have run the benzene ot similar reactions and I know from only one who implemented the heattransfer technique. He (AXT from SCM) was satisfied with the yields he got. Most others not...

Thats one of the topics I feel like Moonmonster, howling at the moon.....
