Abstract: A process for the preparation of organoalkoxysilanes containing one or more organic functional groups derived from organic acids or hydrogen cyanates, by a continuous or batch process utilizing a solid guanidinium salt as a phase transfer catalyst for the reaction between a liquid phase haloalkylalkoxysilane and a solid phase alkali or alkaline earth metal salt or ammonium salt of an organic acid or a metal cyanate.

Abstract: A process is provided for the production of isocyanatosilane from silylorganocarbamate by neutralizing the basic catalyst with an acid to provide an inert metal halide salt, and subjecting the reaction mixture to cracking reaction conditions to obtain isocyanatosilane.

Abstract: Disclosed herein are compounds of the structure 1

Abstract: Disclosed herein are compounds of the structure wherein R1, R2, and R3 are organic radicals of C1 to C20, such that the combination of the three contain at least twelve carbon atoms and R3 is bound to the methylene carbon atom between X and the aromatic ring by at least one saturated carbon atom, allowing it to be easily separated from the polymerizable monomer by distillation; R1 and R2 have sufficient steric bulk to protect the phenol from reacting with an alkoxy group or halogen bound to silicon; and X is a neutral heteroatomic radical of oxygen, nitrogen, or phosphorus; and their use as inhibitors for the polymerization of (meth)acryloxysilanes.

Abstract: Disclosed is a process for making isocyanatoorganosilane by adding a carbamatoorganosilane of the general formula to an inert liquid medium and holding the mixture thus formed at a temperature and pressure effective to convert said carbamatoorganosilane to isocyanatoorganosilane.

Abstract: Aminosiloxanes bearing 4-amino-3,3-dialkylbutyl substituents are prepared by a multistep process including addition of 2,2-dialkylacetonitrile to vinylic siloxanes, hydrogenation of the nitrile adducts so formed to yield 4-amino-3,3-dialkylbutyl siloxanes, and optional equilibration of the latter with other siloxane sources, to form aminosiloxanes, which are useful for the treatment of textiles and fabrics and for the preparation of siloxane-containing block copolymers.
