Abstract: An object of the present invention is to provide a process of producing alkoxysilanes, which does not use a chlorosilane as the intermediate raw material, is improved in view of the environment, and is satisfactory with respect to the yield of a desired material. The present invention is concerned with a process of producing an alkoxysilane including hydrosilylating (A) an organosilicon compound having at least one hydrogen-silicon bond and at least one alkoxy group and (B) an organic compound having a carbon—carbon unsaturated bond in vapor phase in the presence of a mixture containing a hydrosilylation catalyst and a polyalkylene glycol and supported on a carrier, thereby adding hydrogen and silicon of the compound (A) to the carbon—carbon unsaturated bond in the compound (B).

Abstract: A 2-cyanoacrylate composition useful as an adhesive contains a Lewis acid metal salt comprising a metal such as aluminum, gallium, indium or thalium, and the conjugate base of an acid such as a monohalo-, dihalo- or trihalo-acetate (e.g. aluminum trifluoroacetate salt). A clathrate such as a crown ether is also present.

Abstract: A 2-cyanoacrylate composition comprising a cyclic phenol sulfide derivative. The composition has a high curing rate and is excellent in moist-heat resistance, surface curability and clearance curability.

Abstract: A 2-cyanoacrylate composition is disclosed which is excellent in surface curability and clearance curability and effective in shortening the time required for bonding operation. The 2-cyanoacrylate composition contains a Lewis acid metal salt which comprises a specific metal and the conjugate base of an acid having oxygen and in which the metal is bonded to the conjugate base through an oxygen atom and a compound having clathrating ability.
