Abstract
Inventia se refera la un procedeu de separare si purificare a dimetilanilinei din apele reziduale rezultate de la fabricarea acidului 6-aminopenicilanic, si anume din apele mume, dupa distilarea solventilor clorurati, se separa dimetilanilina în conditii normale, prin tratarea întîi cu acid sulfuric 4....5% apoi cu solutie de hidroxid de sodiu 4....5% spalare cu apa în exterior centrifugal uscarea pe exterior centrifugal uscarea pe sita moleculara tip Dusima C-4 si distilarea la 10....15mm Hg.The invention relates to a process for the separation and purification of dimethylaniline from the waste waters resulting from the manufacture of 6-aminopenicillanic acid, namely from the mother liquors after the chlorinated solvents have been distilled, dimethylaniline is separated under normal conditions by first treating with sulfuric acid 4. ... 5% then sodium hydroxide solution 4 ... 5% centrifugal external washing centrifugal drying centrifugal drying drying on molecular sieve Dusima C-4 type and distillation at 10 ... 15 mm Hg.
