Method of preparing organooxy silanes
Abstract
Abstract HALOGEN AND AMINE GROUPS ATTACHED TO SILICON ARE REPLACED BY ORGANOOXY GROUPS. THE REPLACEMENT IS CARRIED OUT WITH THE REACTANTS DISSOLVED IN PENTANE. SUBSTANTIALLY QUANTITATIVE DISTILLED YIELDS ARE OBTAINED, AND THE REACTION CAN BE PRECEDED OR FOLLOWED BY OTHER REACTIONS CARRIED OUT IN THE PENTANE MEDIA. FOR EXAMPLE, TRICHLOROSILIANE IS REACTED WITH AN ORGANO MATERIAL CONTAINING HALOGEN AND AN OLEFINS UNSATURATE. THE SILANE HYDROGEN IS REACTED WITH THE OLEFINIC UNSATURATE, IN A FIRST STAGE REACRION; THE CHLORINES ATTACHED TO THE SILICON ARE REPALCED BY ETHOXY GROUPS IN A SECOND STAGE REACTION; AND THEN THE HALOGEN OF THE ORGANO MATERIAL IS REPLACED BY AMINE IN A THIRD STAGE REACTION, ALL IN THE PENTANE MEDIA. ALL THIS IS ACCOMPLISHED WITHOUT AN HCL SCANVENGER.
