Abstract
Alkylenoksydpolymerisat med en molmasse fra5000 til 35000 fåes ved omsetning av et diol med Cg-alkenoksyder og C-C-alkenoksyder, idet den samlede del av Cg-Calkenoksydet i den polymere utgjør 20 til 80 vekt-%. Det omtales fremgangsmåte til deres fremstilling og deres anvendelse som emulsjons-spalter av råoljer.Alkylene oxide polymer having a molecular weight of from 5,000 to 35,000 is obtained by reacting a diol with C8-alkenoxides and C-C-alkenoxides, the total proportion of the C8-Calken oxide in the polymer being 20 to 80% by weight. The process for their preparation and their use as emulsion columns of crude oils is described.
