Method of using a defoamer

A method for using a defoaming formulation useful as an antifoaming agent, a foam controlling agent, or a defoaming agent. The method comprises adding the defoaming formulation that comprises one or more alkoxylate species to a system, wherein the one or more alkoxylate species is characterized as A...

Zusammenfassung:	A method for using a defoaming formulation useful as an antifoaming agent, a foam controlling agent, or a defoaming agent. The method comprises adding the defoaming formulation that comprises one or more alkoxylate species to a system, wherein the one or more alkoxylate species is characterized as Acc-[(Ox)i]n, wherein Acc is an acceptor having a functionality of n ranging between 1 and about 100. (Ox)i are oxide blocks, each oxide block having a composition comprising from 1 to 150,000 units of oxide species selected from ethylene oxide, propylene oxide, butylene oxide or combinations thereof and i ranges between 1 and about 10. The composition of adjacent oxide blocks is different and the average molecular weight of the one or more alkoxylate species is greater than about 2500 gmole-1. Some embodiments of the present inventions have mixtures of alkoxylate species having average molecular weights between about 5000 and about 3,000,000 gmole-1.
