摘要:A multidentate phosphite ligand is used in the catalytic synthesis of adiponitrile. The ligand is represented by the following general formula (I). The method of catalytic synthesis of adiponitrile comprises primary hydrocyanation, isomerization, and secondary hydrocyanation reactions, wherein the catalyst adopted each comprises a phosphite ligand-nickel complex composed of a nickel precursor and a multidentate phosphite ligand. The ligand molecule has a higher electron cloud density, and the phosphorus content capable of participating in coordination in the ligand molecule per unit mass is higher, so that the catalytic activity of the catalyst is improved, and the amount of the catalyst is reduced.

发明人：LIN JIANG-JEN; KNIFTON JOHN F; YEAKEY ERNEST L
权利人:TEXACO INC
摘要:An N-acetylglycine is manufactured by reacting paraformaldehyde with an acetamide and carbon monoxide in the present of a cobalt-containing catalyst promoted by a sulfoxide or dinitride compounds. The presence of sulfoxide or dinitrile ligands are essential for the high yield synthesis of N-acetylglycine and good cobalt recovery.

标题 :Slurry phase direct synthesis of organohalosilanes from cyclone fines
发明人：LEWIS KENRICK MARTIN; ZHU YANJUN; MEREIGH ABELLARD T; RAZZANO JOHN; NEELY JOHN DAVID
权利人:MOMENTIVE PERFORMANCE MAT INC
摘要:The present invention is directed to a process for the synthesis of organohalosilane monomers, comprising the steps of (1) forming a slurry of cyclone fines, ultra fines and/or spent contact mass in a thermally stable solvent and reacting the agitated slurry with an organohalide of the formula R 1 X in the presence of an additive for a time and at a temperature sufficient to produce organohalosilane monomers having the formulae R 1 SiHX 2 , R 1 2 SiHX, R 1 3 SiX, R 1 SiX 3 , and R 1 2 SiX 2 ; wherein R 1 is a saturated or unsaturated aromatic group, a saturated or unsaturated aliphatic group, alkaryl group, or cycloaliphatic hydrocarbyl group, and X is a halogen; and (2) recovering said organohalosilane monomers.

标 题:Improved synthesis of nickel phosphine and phosphite catalysts
发明人：BRYNDZA HENRY E
权利人:DU PONT
摘要:An improved process for the synthesis of zerovalent nickel catalyst useful for the hydrocyanation of olefins, wherein catalyst formation is improved by applying sonication during formation of catalyst. The sonication may be applied to the catalyst reactant mixture containing elemental nickel and a ligand; or alternatively, the sonication may be applied to the elemental nickel prior to the addition of ligand to the reaction mixture.
