Polyalkoxylated terpenic compounds, their process of preparation and their use as defoaming agents

   
   

The invention concerns polyalkoxylated terpenic compounds of formula Z-X--W--[CH(R.sup.5)--CH(R.sup.6)--O].sub.q -A in which Z is a bicycloheptenyl or bicycloheptyl radical, preferably substituted by methy radicals; X is preferably a --CH.sub.2 --CH.sub.2 --O or O--CH.sub.2 --CH.sub.2 --O-- radical; W is a polysequence, preferably polyoxypropylene and polyoxyethylene; [CH(R.sup.5)--CH(R.sup.6)--O].sub.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.

Las preocupaciones de la invención polyalkoxylated compuestos terpenic del fórmula Z-X -- W -- [CH(R.sup.5) -- CH(R.sup.6) -- O].sub.q - A en la cual Z es un radical del bicycloheptenyl o del bicycloheptyl, substituida preferiblemente por los radicales methy; X es preferiblemente a -- CH.sub.2 -- el --O CH.sub.2 u O -- CH.sub.2 -- CH.sub.2 --O -- radical; W es un polysequence, preferiblemente polyoxypropylene y polyoxyethylene; [ CH(R.sup.5) -- CH(R.sup.6) -- O].sub.q es una secuencia diferente de una secuencia del polyoxyethylene, preferiblemente polyoxypropylene; A es H, un grupo funcional o del hidrocarburo. Pueden ser preparados sucesivamente polyalcoxylating el reactivo Z-XH. Pueden ser utilizados como agentes antiespumosos en medios acuosos que hacen espuma, en detalle en desengrasar medios acuosos en el entorno alcalino de los metales de hoja, así como medios acuosos detergentes en el lavado de la casa o el lavado industrial e institucional.
