Abstract

Inventia se refera la un procedeu pentru prepararea 2,6-diclor-4-nitroanilinei prin clorurarea cu clor gazos ap-nitroanilinei, în solutie apoasa de acid clorhidric, la fierbere si anume reactia se realizeaza la o concentratia a acidului clorhidric de 4....7,5 N, de preferinta 4,5....6 N si la o temperatura cuprinsa între 95 si 110 degree C, de preferinta 105...110 degree C, eventual cu o suprapresiune pîna la 3 bari.The invention relates to a process for the preparation of 2,6-dichloro-4-nitroaniline by chlorination with chlorine gas of ap-nitroaniline in an aqueous solution of hydrochloric acid at boiling, i.e., the reaction is carried out at a concentration of 4% hydrochloric acid. Preferably 7,5 N, preferably 4,5 ... 6 N, and at a temperature comprised between 95 and 110 C, preferably 105 ... 110 C, possibly with an overpressure of up to 3 bar.
