Abstract

Oppfinnelsen vedrører en fremgangsmåte for isolering av metylglycinnitrill-N,N-diacetonitrill (MGDN) fra en vandig emulsjon omfattende MGDN og har et MGDN innhold på 3 til 50 vekt% i en krystallisator, omfattende trinnene: (a) den vandige emulsjon avkjøles ved å gå ut fra en temperatur over størkningspunktet, til en temperatur under størkningspunktet, idet avkjølingstakten gjennomsnittlig over tid ikke overstiger 5?K/h, inntil hovedsakelig hele mengden av det emulgerte MGDN har størknet, (b) den resulterende vandige suspensjon avkjøles videre og/eller konsentreres, idet avkjølingstakten da kan være større enn i trinn (a).
