Catalyzer

1. It is used for the surface treatment of glass fiber and the treatment of reinforced plastic laminates. It can condense with silanol on the glass surface, form a covalent bond with glass, and improve the relationship between glass fiber and unsaturated polyester, epoxy resin, and acrylic acid. Adhesiveness, heat resistance, water resistance of resin etc. It is also used as a coupling agent for filler silica for rubber, as a modifier for chlorine-containing resins, and as a raw material for the synthesis of various silicone products. 2. Used in organic synthesis, as an intermediate in the manufacture of silicone, as a coupling agent for adhesives and as a chemical reagent.

Titanium tetrachloride is the most important titanium halide. It is an important raw material for the production of titanium sponge and titanium dioxide by chlorination. Pure titanium tetrachloride is a colorless, transparent, dense, non-conductive liquid with pungent acid taste, easy to hydrolyze, and generates white smoke in humid air. It dissolves in water and decomposes at the same time. It also dissolves in alcohol and concentrated hydrochloric acid, and is mutually soluble with chloroform and carbon tetrachloride. Titanium tetrachloride is prepared by mixing titanium dioxide, carbon powder and maltose, then coking, adding chlorine above 600 ℃ or chlorinating with chlorinating agent (such as carbon tetrachloride). Titanium tetrachloride is also an important component of ethylene polymerization catalyst. It is used as smoke agent in military and mordant in dye industry.

N-methyldicyclohexylamine is a tertiary amine. Tertiary amines, especially n-methyldialkyl amines, as important intermediates in chemical industry, have great economic importance. They are used as vulcanization accelerators in the rubber industry and as catalysts for polymerization and curing in the production of plastic molds based on epoxide and polyurethane. They are also suitable for use as corrosion inhibitors and as raw materials for detergents and flocculants. As an important intermediate for the preparation of substances used in the field of crop protection or pharmaceutical products, n-methyldialkylamine is also very important.

R - (+) - 1,1 '- binaphthyl-2,2' - diphenylphosphine can be used as an effective ligand for transition metal catalyzed asymmetric reactions (including hydrogenation and dimethylsilylation). 2,2 ′ - bis (diphenylphosphine) - 1,1 ′ - binaphthyl and its rhodium and ruthenium derivatives can be used as highly selective homogeneous catalysts for the synthesis of aryl ketones β- Keto esters and α- Reduction of aminoketones. It can also be used in asymmetric hydrogenation and hydroformylation of olefins, asymmetric Heck reaction and asymmetric isomerization of allyl.

It can be used as homogeneous catalyst with high selectivity.
