标 题:Preparation of 1,4-diols by hydrolysis-hydrogenation of 2-alkoxytetrahydrofurans
发明人：SMITH WILLIAM EDWARD
权利人:GEN ELECTRIC
摘要:2-ALKOXYTETRAHYDROFURANS ARE CONVERTED TO 1,4-DIOLS UNDER HYDROLYSIS-HYDROGENATION CONDITIONS. The method may be coupled with the synthesis of 2-alkoxytetrahydrofurans to provide a highly efficient, two-step conversion of allylic alcohols to butanediols.

标题 :Preparation of enamines from conjugated dienes
发明人：LIN JIANG-JEN
权利人:TEXACO INC
摘要:A method for the preparation of enamines wherein a conjugated diene is reacted with a secondary amine, carbon monoxide and hydrogen (synthesis gas) in solvent solution in the presence of a rhodium catalyst. In accordance with the preferred embodiment, butadiene is reacted with a dialkylamine and synthesis gas in an organic solvent in the presence of a rhodium catalyst to provide the corresponding 1,3-pentadienyl dialkylamine in good yield and with good selectivity. This may be illustrated, for example, by the following equation: H3CCHCHCHCHNR2 + H2O

标 题:Process for preparing acetaldehyde from methanol and synthesis gas using a novel catalyst composition
发明人：LIN JIANG-JEN; KNIFTON JOHN F
权利人:TEXACO INC
摘要:Acetaldehyde is prepared in good yield from methanol and synthesis gas under mild reaction conditions by contacting a mixture of methanol, carbon monoxide and hydrogen with an iodide or iodine free catalyst composition comprising (1) ruthenium powder, (2) a cobalt-containing compound (3) a rhodium-containing compound, and (4) an onium salt or base, and heating the resulting mixture under mild temperature and pressure for sufficient time to produce the desired acetaldehyde, and then recovering the same from the reaction mixture.

标 题 :Process for formation of dialkylaminomethylated internal olefin polymers
发明人：MCENTIRE EDWARD E; KNIFTON JOHN F
权利人:TEXACO INC
摘要:An aminomethylation reaction is disclosed wherein polymeric polyamines are produced. Polymeric polyolefins such as polybutadiene, secondary amines, and synthesis gas are reacted in the presence of a catalyst system comprising a ruthenium-containing compound, a rhodium-containing compound, a sterically hindered phosphine and a solvent. Preferred polybutadiene feedstocks are those with a predominance of internal rather than pendant vinylic olefin groups and particularly those polymers containing both the 1,2-polybutadiene and 1,4-polybutadiene units.

标题:Process for the selective hydroformylation of terminal olefin groups and its use in the preparation of 1,4-butanedial monoacetal
发明人：ICHIKAWA SHUJI; FUJITA AKIKO; SUMITANI NAOKO; OHGOMORI YUJI
权利人:MITSUBISHI CHEM CORP
摘要:A process for producing 1,4-butanedial monoacetal by reacting acrolein acetal with a synthesis gas containing carbon monoxide and hydrogen, in the presence of a rhodium catalyst and an accelerator of formula (I) ##STR1## wherein R 1 and R 2 each, independently, denote a hydrogen atom, a C 1 -C 20 alkyl group or a C 6 -C 20 aryl group, or R 1 and R 2 together form a --(CH 2 ) n -- group, n is an integer of from 2 to 7, R 3 and R 4 each, independently, denote halogen or a trifluoromethyl group, and p and q are each, independently, an integer of from 0 to 3, which process can also be extended to the hydroformylation of other compounds which contain an olefin group in a terminal position.

标题:Catalytic process for the preparation of tetrahydropyran by homologation of tetrahydrofuran
发明人：BEAVERS WILLIAM A
权利人:EASTMAN KODAK CO; EASTMAN KODAK CO
摘要:The present invention relates to a catalytic process for the preparation of tetrahydropyran by the homologation of tetrahydrofuran. The process comprises reacting tetrahydrofuran with synthesis gas in the presence of a catalyst system comprising ruthenium, rhodium, and, preferably, a halide promoter.
