Abstract
Inventia se refera la un procedeu de obtinere a tert-butilaminei din acetonitril si izobutena continuta în fractiunea C4 la N-tert-butil-acetamida, care se hidrolizeaza în mediu alcalin la tert-butilamina si acetatul respectiv. Prin procedeul descris se condenseaza acetonitrilul cu izobutena în apa, în prezenta acidului sulfuric, prin contactarea reactantilor în sistem gaz-lichid sau lichid-lichid, urmata de neutralizarea cu solutie apoasa de NaOH antrenarea cu vapori N-tertbutilacetamidei obtinute. Solutia apoasa se trateaza cu NaOH si se supune procesului de hidroliza alcalina prin încalzire la 130...170 degree C.
