PROCESS FOR PREPARING ETHER-CAPPED POLY(OXYALKYLATED) ALCOHOL SURFACTANTS

摘要

A process for preparing an ether-capped poly(oxyalkylated) alcohol surfactant is provided. The alcohol has the formula: RO(R<1>0)xCH(CH3)OR<2> wherein, R is selected from the group consisting of linear or branched, saturated or unsaturated, substituted or unsubstituted, aliphatic or aromatic hydrocarbon radicals having from about 1 to about 30 carbon atoms; R<1> may be the same or different, and is independently selected from the group consisting of branched or linear C2 to C7 alkylene in any given molecule; x is a number from 1 to about 30; and R<2> is selected from the group consisting of: (i) a 4 to 8 membered substituted, or unsubstituted heterocyclic ring containing from 1 to 3 hetero atoms; and (ii) linear or branched, saturated or unsaturated, substituted or unsubstituted, cyclic or acyclic, aliphatic or aromatic hydrocarbon radicals having from about 1 to about 30 carbon atoms; provided that when R<2> is (ii) then either at least one of R<1> is other than C2 to C3 alkylene or R<2> has from 6 to 30 carbons atoms.
