POLYALKOXYTERPENOIDE, VERFAHREN ZU IHRER HERSTELLUNG UND IHRE VERWENDUNG ALS ENTSCHAUMUNGSMITTEL

摘要

The invention concerns polyalcoxylated terpenic compounds of formula Z-X-W-[CH(R<5>)-CH(R<6>)-O]q-A in which Z is a bicycloheptenyl or bicycloheptyl radical, preferably substituted by methyl radicals; X is preferably a -CH2-CH2-O or -O-CH2-CH2-O- radical; W is a polysequence, preferably polyoxypropylene and polyoxyethylene; [CH(R<5>)-CH(R<6>)-O]q is a sequence different from a polyoxyethylene sequence, preferably polyoxypropylene; A is H, a functional or hydrocarbon group. They can be prepared by successively polyalcoxylating the reagent Z-XH. They can be used as antifoaming agents in foaming aqueous media, in particular in degreasing aqueous media in alkaline medium of sheet metals, as well as detergent aqueous media in household washing or industrial and institutional washing.
