ABSTRACT:
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, urea, 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 form.
