Abstract
Inventia se refera la un procedeu pentru obtinerea clorhidratului de 2-amino-5-clor-toluen, conform caruia, în prima faza se efectueaza acetilarea o-toluidinei cu anhidrida acetica la temperatura de 40....130 degree C, în mediu de acid acetic glacial, dupa care urmeaza clorurarea acetilderivatului rezultat, la temperatura de 20....28 degree C în acelasi solvent si în final, hidroliza cu acid clorhidric de concentratie 17% la temperatura de 90....95 degree C, recirculînd solutiile muma în fiecare din cele trei faze.
