HETEROGENEOUS ORGANOTIN CATALYSTS

摘要

THIS INVENTION PROVIDES : (A) NEW ORGANOTIN FUNCTIONALIZED SILANES : (B) A SOLID PREPARED BY CHEMICALLY BONDING ORGANOTIN FUNCTIONALIZED SILANES TO A SOLID INORGANIC SUPPORT CONTAINING SURFACE HYDROXY GROUPS : (C) A SOLID CATALYST PREPARED FROM SAID SUPPORTED ORGANOTIN FUNCTIONALIZED SILANE; (D) A PROCESS FOR CONDUCTING ESTERIFICATION OR TRANSESTERIFICATION , AND URETHANE, AREA, SILICONE, AND AMINO FORMING REACTION UTILIZING SAID SOLID SUPPORTED CATALYST; (E) A PROCESS OF SEPARATING THE SOLID SUPPORTED CATALYST FROM THE REACTION PRODUCTS EMPLOYING LIGAND-SOLID SEPARATION TECHNIQUES; (F) REUSE OF THE SOLID SUPPORTED CATALYST AFTER BEING SEPARATED FROM THE REACTION PRODUCTS; (G) A CONTINUOUS ESTERIFICATION OR TRANSESTERIFICATION REACTION OR URETHANE, UREA, SILICONE,OR AMINO FORMING REACTION OR URETHANE, UREA, SILICONE, OR AMINO FORMING REACTION COMPRISING PASSING REACTANTS FOR A ESTERIFICATION OR TRANSESTERIFICATION REACTION OR URETHANE, UREA, SILICONE, OR AMINO FORMING REACTION OR A URETHANE, UREA, SILICONE, OR AMINO FORMING REACTION OR A URETHANE, UREA SILICONE OR AMINO FORMING REACTION THROUGH A REACTOR CONTAINING A CATALYTICALLY EFFECTIVE AMOUNT OF SAID SOLID SUPPORTED CATALYST TO FORM ESTERIFICATION OR TRANSESTERIFICATION REACTION A COR A URETHANE, UREA, SILICONE, OR AMINO FORMING REACTION OR A URETHANE, UREA, SILICONE, OR AMINO FORMING REACTION PRODUCTS IN SAID REACTOR AND REMOVING SAID REACTION PRODUCTS FROM SAID REACTOR; AND (H) ESTERIFICATION OR TRANSESTERIFICATION REACTION OR A URETHANE, UREA, SILICONE, OR AMINO FORMING REACTION OR URETHANE, UREA, SILICONE, OR AMINO FORMING REACTION PRODUCTS PRODUCED WITH SAID SOLID, SUPPORTED, TIN-CONTAINING CATALYST AND SAID REACTION PRODUCTS CONTAINING LESS THAN 100PPM TIN BY WEIGHT; AND (I) THE SYNTHESIS OF ORGANOTIN SILANES WITH AND WITHOUT A LEWIS ACID.
