Title: A process for the manufacture of organosilicon esters
IPC: C07F7/18
Filed: 1954-11-11
Abstract: Esters of silanes and of polysiloxanes are prepared by heating a partially or completely condensed organosiloxane containing units RnSiO4-n,/2 where R is a monovalent hydrocarbon radical and n has an average value of 2 to 3, with a primary or secondary monohydric or dihydric alcohol whose boiling point exceeds that of isopropanol, in the presence of an alkali metal hydroxide catalyst, with continuous removal from the reaction zone of the water formed by the reaction. The siloxane reactants may vary from thin liquids to solids. Suitable alcohols are the butyl, amyl, hexyl and octadecyl alcohols, ethylene and hexylene glycols, cyclohexanol and cyclopentanol, and alcohol ethers such as tripropylene glycol and the monomethyl ether of ethylene glycol.  With monohydric alcohols, one equivalent of alcohol per equivalent of siloxane produces a silane ester, while polysiloxane esters are produced when the proportion of alcohol is less. Dihydric alcohols yield polymeric esters.  The water may be removed by normal stripping or by adding a water-reactive agent such as calcium oxide, or, preferably by using as reaction medium a hydrocarbon solvent which is water-immiscible and forms an azeotrope therewith, e.g. benzene, toluene or xylene.  Reaction is then effected by refluxing and the distillate is collected in a water-trap.  The examples describe the preparation of (1) di-n-butoxydimethyl silane; (2) diphenyl di-2-ethylhexane; (3) dioctadecyloxyphenyl methyl silane; (4) di-2-octyloxy dimethyl silane; (5) dicyclohexyloxydiphenyl silane; (6) monoethyl ethertripropoxy ester of dimethyl silane; (7) dimeric dimethylethylene dioxy silane (-Si(Me2)OCH2CH2O)2; (8) dimethyl di-n-propoxy silane.
