ABSTRACT:
The present invention relates to a method of preparing dimeric or polymeric organosilane esters whose ester component is at least one glycol moiety and whose silicon atoms are linked together by a glycol moiety. These compounds are known and are used as hydraulic fluids whose preparation involves considerable difficulty. The present invention avoids these difficulties by setting out from organosilane diglycol esters or triglycol esters and transposing them with diglycols or polyglycols. In this transposition the glycol ether corresponding to the glycols is formed and is removed by distillation. The degree of condensation of the organosilane ester products depends on the weight-ratio of the organosilane glycol ester to the diglycols or polyglycols.
