摘要 |
<p>(1) Process for the manufacture of 2,6-dichloro-4-nitroaniline. (2) This process consists in chlorinating paranitroaniline, with chlorine gas, in an aqueous solution of hydrochloric acid having a concentration of between 4 and 7.5 N, at the boil, at a temperature between 95 DEG and 110 DEG C. (3) This process makes it possible to obtain 2,6-dichloro-4-nitroaniline with an improved yield and an improved quality of product.</p> |
