Abstract
Prezenta inventie se refera la un procedeu pentru sinteza acetonitrilului utilizând un catalizator constituit din site moleculare acide tip YH, depus în reactoare izoterme sau adiabatice, alimentate cu materii prime constituite fie din solutie apoasa de acetat de amoniu de concentratie de 20...60% g, fie din acid acetic glacial si o solutie apoasa amoniacala de concentratie 25% g, care se dozeaza si se contacteaza înainte de preîncalzitor-evaporator, lucrându-se la presiune atmosferica, la temperaturi cuprinse între 250 si 450 degree C, la viteze volumare de 0,3...1 h supra -1, timpi de contact de 1...3 s, raporturi molare NH3/acid acetic de 1,1...3/1.
