  • Patent number: 10273254
    Abstract: A process for preparing an acryloyloxysilane, comprising: reacting a metal salt of a carboxylic acid having the formula [CR22?CR1CO?]aMa+??(I), with a haloorganoalkoxysilane having the formula XR3Si(OR4)nR53-n??(II) at a temperature of from 50 to 160° C. and in the presence of a catalyst, and in the presence of water, an alcohol comprising 1 to 5 carbon atoms, or a combination of water and an alcohol comprising 1 to 5 carbon atoms, to form a mixture comprising an acryloyloxysilane and a metal halide having the formula Ma+X?a??(III), wherein R1 is H, R7COO?Ma+, or C1-C6 hydrocarbyl, each R2 is independently R1 or [COO?]Ma+, Ma+ is an alkali metal cation or alkaline earth metal cation, a is 1 or 2, X is halo, R3 is C1-C6 hydrocarbylene, each R4 is independently C1-C10 hydrocarbyl, each R5 is independently R1 and n is an integer from 1 to 3.

  • Patent number: 7090812
    Abstract: A method and system for reactively destroying alkyl halides in volume or stream of gas. The method and device employ nucleophilic reaction of the alkyl halide under phase transfer catalysis conditions. The method and system are useful for scrubbing applications requiring the reduction of alkyl halide concentrations to very low levels.

  • Patent number: 6846946
    Abstract: A method for preparing organic products from aqueous solutions, such as waste or byproduct liquid streams and waste or byproduct gas or vapor streams, uses phase transfer catalysis to transfer a chemical species in low concentration from the aqueous solution to the organic phase or the aqueous-organic interface. The system has little or no organic solvent, and the organic phase contains an electrophile which participates in the reaction. In one embodiment, the aqueous solution is contacted with the electrophile and a phase transfer catalyst and, optionally, a pH adjusting agent in the event that the chemical species in the aqueous solution is not sufficiently ionized to react with the electrophile, and optionally an organic solvent. A method for continuously converting a chemical species involves this contacting step, separating the phases, then dividing the organic phase into the product, the phase transfer catalyst, and the optional organic solvent.
