Patent number: 4395564Abstract: A process whereby silanes of the general formula:HSi(NRR').sub.x (R").sub.3-xwherein R, R' and R" are independently an aliphatic or aromatic, substituted or unsubstituted, saturated or unsaturated hydrocarbon radical having from one to eight carbon atoms, inclusive and R and R' may also be hydrogen and where R" may also be alkoxy and where x has a value from one to three are reacted in the presence of a catalyst with alcohols in the stoichiometry of approximately one equivalent of alcohol per mole of silicon-nitrogen bond to give unexpectedly high yields of alkoxyhydridosilanes. In the reaction the silyl amine groups have been replaced by alkoxide groups without significant loss of the silicon-hydrogen group. Similar reactions in the absence of a catalyst give undesirably low yields of the corresponding alkoxy silanes and, in most cases, substantial loss of silyl hydrogen groups.Type: GrantFiled: July 13, 1982Date of Patent: July 26, 1983Assignee: Union Carbide CorporationInventors: Bernard Kanner, Steven P. Hopper

Patent number: 4093642Abstract: This invention relates to ion-pair-containing siloxane compounds that are extremely effective as surface tension depressants. The compounds of the present invention contain both anionic and cationic substituents and can be formed by metathesis reactions between metallic salts of anionic silicone or organic surface-active compounds and halide salts of quaternary ammonium silicone or organic surface-active compounds. The compounds of the invention are relatively pH insensitive when compared to siloxanes bearing anionic and cationic substituents that are formed by proton transfer. Thus, the organosilicon compounds of the invention will remain stable despite changes in pH of the mixture in which they are present.Type: GrantFiled: December 20, 1976Date of Patent: June 6, 1978Assignee: Union Carbide CorporationInventors: Curtis L.
