Abstract
Inventia se refera la un procedeu de obtinere a p-anisidinei, intermedir folosit în industria colorantilor si medicamentelor, prin metoxilarea nitroclorbenzenului, separarea nitroanisolului direct din masa de reactie, operatii urmate de reducerea cu sulfura de sodiu si cristalizarea p-anisidinei prin diluare cu apa si racire.The invention relates to a process for obtaining p-anisidine, intermediates used in the dyestuffs and drugs industry, by nitroxybenzene methoxylation, separation of nitroanisole directly from the reaction mass, operations followed by reduction with sodium sulfide and crystallisation of p-anisidine by dilution with water and cooling.
