Alkoxylate mixture used in laundry and cleaning detergents for washing and cleaning textiles contains alkoxylates of alkanols with different chain lengths with ethylene oxide and optionally other alkylene oxide(s)

摘要

Alkoxylate mixture contains 0.1-99.9 wt.% alkoxylate(s) (I) of 8-11 carbon (C) alkanol(s) and 0.1-99.9 wt.% alkoxylate(s) (II) of 12-24 C alkanol(s), in which (I) has 1-20 and (II) has 1-50 ethylenoxy groups, (I) and (II) have 0-10, optionally mixed 3-10 C alkylenoxy groups and the ethylenoxy and other alkylenoxy groups have random or alternating distribution or are in 2 or more blocks in any sequence. Alkoxylate mixture contains 0.1-99.9 wt.% alkoxylate(s) (I) and 0.1-99.9 wt.% alkoxylate(s) (II) of the given formulae, in which the ethylenoxy and other alkylenoxy groups have random or alternating distribution or are in 2 or more blocks in any sequence: R1 = CnH2n+1; R2 = CmH2m+1; A = ethylenoxy; B = 3-10 C alkylenoxy or a mixture of such groups; n = 8-11; m = 12-24; x = 1-20; = 1-50; y, w = 0-10 . An Independent claim is also included for production of the alkoxylate mixture by reacting the corresponding alkanols with 2-5 C alkylene oxides under alkoxylation conditions, using a double metal cyanide compound as catalyst, and mixing them before or after alkoxylation or after partial alkoxylation.
