Process for the transesterification of alkoxy-containing organosilicon compounds

Claim 1

AN IMPROVED PROCESS FOR THE TRANSESTERIFICATION OF AN ALKOXY-CONTAINING ORGANOSILICON COMPOUND WITH A HYDROXY-CONTAINING ORGANIC COMPOUND WHICH COMPRISES REACTING AN ORGANOSILICON COMPOUND CONTAINING AT LEAST ONE ALKOXY GROUP ATTACHED TO SILICON AND A HYDROXY-CONTAINING ORGANIC COMPOUND SELECTED FROM THE CLASS CONSISTING OF MONOHYDRIC ALIPHATIC HYDROCARBON ALCOHOLS, GLYCOLS, PHENOLS AND HYDROXY-CONTAINING POLYOXYALKYLENE ETHERS IN CONTACT WITH AN ORGANIC ACID SELECTED FROM THE CLASS CONSISTING OF ALIPHATIC ACIS, CHLORINATED ALIPHATIC ACIDS AND PERFLUORO ALIPHATIC ACIDS AND A BASEIC COMPOUND SELECTED FROM THE CLASS CONSISTING OF THE ALKALI METAL HYDROXIDES OF THE ALKALI METALS HAVING AN ATOMIC NUMBER GREATER THAN 11 AND THE ORGANIC ACID SALTS THEREOF, AMMONIUM HYDROXIDE AND THE ORGANIC ACID SALTS THEREOF, THE QUATERNARY ALKYL AMMONIUM HYDROXIDES AND THE ORGANIC ACID SALTS THEREOF, THE NITROGEN-CONTAINING ORGANIC BASES CONTAINING A TRIVALENT NITROGEN ATOM AND THE ORGANIC ACID SALTS THEREOF, SAID ORGANIC ACID BEING PRESENT IN EXCESS OF THE STOICHIOMETRICALLY EQUIVALENT AMOUNT NECESSARY FOR COMPLETE REACTION WITH SAID BASE.
