Abstract
Inventia se refera la un procedeu de obtinere a spumantilor neionici sintetici pe baza de metil polipropilenglicoli conform caruia în scopul obtinerii directe din sinteza chimica a produselor finite cu un grad de puritate cuprins între 88-95% printr-o conversie maxima a materiilor prime se realizeaza continuu propoxilarea la o concentratie a catalizatorului de 0,2.....1% fata de amestecul de reactie prin doua sau trei treceri succesive ale rectantilor într-un reactor tubular la rapoarte molare initiale metanol 1: propenoxid cuprinseîntre 2: 1 si 1: 5 succesiv la rapoarte molare produs de reactie propenoxid cuprinse între 1: 1 si 1: 4 si respectiv între 1: 0,5 si 1: 2,5.
