标题:Process for the preparation of imidazolidine-2, 4-diones
发明人：BELLER MATTHIAS; ECKERT MARKUS; MORADI WAHED
权利人:DEGUSSA
摘要:A process for the preparation of compounds of the general formula (I)by reacting an aldehyde compound of the general formula (II)with a urea compound of the general formula (III)in the presence of carbon monoxide and a catalytically active metal compound. Compounds of the general formula (I) are important intermediates for the synthesis of alpha-amino acids.

标题:Manufacture of ethylene from synthesis gas (D#75,673-C1)
发明人：KNIFTON JOHN F
权利人:TEXACO INC
摘要:This invention concerns a two-step process for the preparation of ethylene from mixture of carbon monoxide and hydrogen (commonly known as synthesis gas) by reaction of said carbon monoxide/hydrogen mixtures with a carboxylic acid in the presence of one or more ruthenium catalyst complexes to form an ethyl ester of said carboxylic acid coreactant, followed by pyrolysis of said ethyl ester intermediate to ethylene.

标题:Alcohols prepared from olefins and synthesis gas
发明人：KNIFTON JOHN F
权利人:TEXACO INC
摘要:This invention concerns a process of preparing predominantly linear alcohols which comprises the steps of contacting a mixture of terminal and/or internal olefins and synthesis gas with a catalyst system comprising a ruthenium-containing compound coupled with one or more bidentate or multidentate, phosphine-containing promoters, dispersed in a low melting quaternary phosphonium salt, and heating said resultant reaction mixture under a pressure of 100 psi or greater at a temperature of at least 50 DEG C. for a sufficient time to produce said alcohols.

标题 :Process for preparing alcohols from olefins and synthesis gas
发明人：KNIFTON JOHN F; GRIGSBY JR ROBERT A
权利人:TEXACO INC
摘要:This invention concerns an improved process of preparing predominantly linear alcohols which comprises the steps of contacting a mixture of terminal and/or internal olefins and synthesis gas with a catalyst system comprising a ruthenium-containing compound in conjunction with one or more tertiary amine promoters, dispersed in a low melting quaternary phosphonium salt and heating said resultant reaction mixture under a pressure of 100 psi or greater at a temperature of at least 50 DEG C. for a sufficient time to produce said alcohols.
