Abstract
Inventia se refera la un procedeu pentru prepararea 3-picolinei din acetalhida, formaldehida si amoniac, constînd din aceea ca se trateaza acetaldehida cu formaldehida în raport molar de 1: 0,80 în vas închis, în faza lichid apoasa, la temperaturi cuprinse între 230 si 240 degree C, în prezenta amoniacului si a unei amide de acid carboxilic, utilizata în cantitati de 0,1 pîna la 0,8 mol fata de suma molara acetaldehidaformaldehida.
