Synthetic Route of 13940-96-0, The chemical industry reduces the impact on the environment during synthesis 13940-96-0, name is 4-Phenoxybenzene-1,2-diamine, I believe this compound will play a more active role in future production and life.
In a 1000 ml flask equipped with a stirring blade and a reflux condenser, 750 g of a methyl t-butyl ether solution containing 12% by mass of 3,4-diaminodiphenyl ether and 150.8 g (1.13 mol) of acetic anhydride were charged, The reaction was carried out for 2 hours under heating reflux. From the reaction solution, about 500 g of methyl t-butyl ether was distilled off under reduced pressure to obtain a concentrated solution. The obtained concentrated liquid was poured into 1,000 g of a 20% sodium hydroxide aqueous solution to precipitate an N, N-diacetylated product of 3,4-diaminodiphenyl ether to obtain a solid-liquid mixture.
In the field of chemistry, the synthetic routes of compounds are constantly being developed and updated. I will also mention this compound in other articles, 4-Phenoxybenzene-1,2-diamine, other downstream synthetic routes, hurry up and to see.
