acetic anhydride synth ( acetone&co2)
ambi:
I am not sure if anyone has mentioned this ever, but after a lil' searching, couple'a key words changed, the patent Patent GB237302 popped up,.
I believe this will have a wide impact on otc chemistry as we know it,.
I couldn't believe it myself, but when the vapour of acetone and co2 are heated, Acetic anhydride is elegantly formed,.
Plus, it's isolation and purification coudn't be easier,.
I am proud to bring this news, and reallize all the goodies that can be made with AA,.

thankyou
ambi ;)
Rhodium:
It's not especially new - UTFSE for "ketene lamp"
ambi:
The patent, describes heating the vapours of acetone & Co2,
the ketene involves a lamp, and no co2,.
Have you read the patent?
Running a tube of co2 through boiling acetone, is a hell of a lot different than the ketene method, maybe the chemistry is vaguely similar, but this is simple, and rquires no electricity,.
lugh:
It's clear that you haven't read the patent thoroughly, pressure catalyzed processes aren't practical for the average bee, but some do have the capability ;) The keten lamp is far more practical for the average bee, it also utilizes acetone, and doesn't require pressure ;D If you keep researching the topic, you'll many more industrial process patents like the one you found:
Patent GB237302
for example
Patent GB309577
Patent GB425973
and Patent GB668268

roger2003:
The critical temperature is 31,3° C and the critical pressure 72,9 bar
If you work with the above patent, you need a lot of technical security systems.
