Abstract

Processo multistadio per la preparazione di mono- e dissocianati alchilici consistente nel far reagire la corrispondente ammina o diammina alifatica con dimetilcarbonato, e, sostanzialmente, nel vaporizzare e convertire parzialmente l'uretano così formatosi in un evaporatore per poi terminare il cracking in un II° reattore, ed infine nel sottoporre a distillazione frazionata a pressione ridotta il prodotto del cracking con riciclo della parte non convertita allo stadio di vaporizzazione parziale.
