标 题:Process for synthesis of glutamic acid from acrylate, amide and synthesis gas
发明人：LIN JIANG-JEN
权利人:TEXACO INC
摘要:A process for the synthesis of glutamic acid intermediate from an acrylate, amide and syngas by reacting them in the presence of a catalyst comprising a cobalt-containing compound, a bis-phosphine ligand and a solvent at a pressure of at least 500 psi and a temperature of at least 50° C. and thereafter extracting the glutamic acid.

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 :Synthesis of substituted dioxolanes by direct oxidation of olefins over molybdenum 8-hydroxyquinoline

摘要:The synthesis of substituted dioxolanes by direct oxidation of olefins over a molybdenum 8-hydroxyquinoline catalyst in the presence of water is described. An organic solvent such as chlorobenzene may also be employed. Water is essential to the reaction to make the dioxolanes, otherwise olefin oxides are produced. Hence, 4-methyl-1,3-dioxolane and 2,4-dimethyl-1,3-dioxolane were prepared from propylene oxidation, and three isomers of 2,4,5-trimethyl-1,3-dioxolane were prepared from 2-butene oxidation.

标题:Process for synthesis of a novel amino acid from styrene, acetamide and syngas
发明人：LIN JIANG-JEN
权利人:TEXACO INC
摘要:A phenyl substituted amino acid derivative is synthesized by reacting styrene, acetamide and synthesis gas with a bimetallic catalyst comprising a rhodium-containing compound and a cobalt-containing compound, optionally in the presence of a solvent at a pressure of at least 500 psi and a temperature of at least 50° C. The novel amino acid contains a carboxylic acid group, an acetamido group at the alpha-position and a phenyl group at the beta-position.

标题:Process for synthesis of amidoacids using a cobalt catalyst and a bidental phosphine ligand
发明人：LIN JIANG-JEN
权利人:TEXACO INC
摘要:A process is disclosed for producing N-acetyl-aminoacid which comprises reacting a feedstock from the group consisting of simple olefins, acetamide and synthesis gas with a catalyst comprising a cobalt-containing compound promoted by a bidental-phosphine ligand in a solvent at a pressure of 500 psi or greater and a temperature of 50 DEG C. or greater. The presence of the ligand increases both reaction rate and cobalt catalyst stability.

标 题 :Process for synthesis of β-phenylalanine
发明人：LIN JIANG-JEN; KNIFTON JOHN F
权利人:TEXACO INC
摘要:N-acetyl-β-phenylalanine is synthesized by reacting phenylacetaldehyde, acetamide and synthesis gas with a catalyst comprising a cobalt-containing compound in conjunction with a cocatalyst that may be either a Group VB or VIB containing ligand, or a rhodium compound optionally bonded to one or more Group VB or VIB donor ligands, at a temperature of at least 50° C. and a pressure of at least 500 psi.
