Question

Can you help me to design a diagram to separate a mixture of benzyl acid and p-toluidine, indicating in it the processes of separation, purification, and identification of each of the components?

Answer 1

daus GOBH and Take the Mintture chloroform (CHCR Ја соз . - of po benzel acid and to-toluicine in and Contract the mixture with 10% 10% Notroz NH Haloo Nat СН3 in water un chlonform doo Sime at forms a salts and comescent and it remains and the the wath. chowform So, By separating tunnel water and chlonform layls can be Seperated.
