https://www.thevespiary.org/rhodium/Rhodium/chemistry/equipment/nomograph.html
i have drew a line from 375 torr to 215°C (P2P) and the p2p must distill at 185°C. I have made it but I only get the acetic acid anhydrid. what did i wrong.
The p2p made I after a synthesis of the book from otto snow.
Phenyl acetic acid sodium acetate and acetic acid anhydrid. Heatet for 18h at 150°C. After that distill only the p2p.
thx for all replys
