标题:Process for the preparation of beta-gamma unsaturated esters
发明人：BURKE PATRICK MICHAEL
权利人:DU PONT; DSM NV
摘要:A process for the carbonylation of allylic butenyl ether (e.g., methyl crotyl ether, 3-methoxybutene-1 and mixtures thereof) or mixture of butadiene and alcohol (e.g., methanol) and production of beta-gamma unsaturated carboxylic acid esters (e.g., methyl-3-pentenoate) utilizing a rhodium-containing catalyst (e.g., dicarbonylacetylacetonate rhodium(I) or the like) promoted with an iodide-containing compound (e.g., HI, AlI3, SnI4, TiI4, CrI3, and CoI2 or the like). Such a process is particularly useful in the production of difunctional monomers and intermediates in the synthesis of adipic acid. The representative reaction showing (a) butadiene in the presence of methanol under catalytic reaction conditions producing the 3-methoxybutene-1 intermediate (a positional isomer of methyl crotyl ether) which is then combined with carbon monoxide to produce methyl pentenoate is illustrative of the overall carbonylation.

标 题 :Synthesis of alcohols
发明人：IMAI TAMOTSU; HOMEIER EDWIN H
权利人:UOP INC
摘要:Alcohol may be synthesized by treating olefinic hydrocarbons with carbon monoxide and hydrogen in a hydroformylation zone utilizing a rhodium complex catalyst to effect the reaction. Following formation of the alcohol, the catalyst may be extracted from the alcohol by treatment with an aqueous ammonium hydroxide solution. Thereafter the aqueous ammonium hydroxide solution containing the catalyst is then stripped of ammonia by treatment with carbon monoxide or carbon monoxide containing gas. The aqueous ammonium hydroxide solution containing the rhodium complex catalyst is then stripped of a portion of water and the remaining solution is thereafter recycled to the hydroformylation zone.

标 题 :Synthesis of alcohols by hydroformylation with nitrile promoter
发明人：IMAI TAMOTSU
权利人:UOP INC
摘要:Alcohols may be synthesized by reacting an olefinic compound, carbon monoxide and hydrogen in the presence of a Group VIII organometallic complex catalyst at reaction conditions which include a temperature in the range of from about 50° to about 250° C. and a pressure in the range of from about 10 to about 300 atmospheres. In addition, the reaction is also effected in the presence of a promoter compound comprising a nitrile.

标题 :Preparation of alkylidene diesters
发明人：PAULIK FRANK E; SCHULTZ ROBERT G
权利人:MONSANTO CO
摘要:Alkylidene diesters such as ethylidene diacetate are produced by reacting an ether and/or an ester under substantially anhydrous conditions with carbon monoxide and hydrogen in contact with a catalyst system comprising a rhodium compound and a halogen component at a temperature in the range from 125° to 300° C. and at a carbon monoxide partial pressure in the range from about 1.0 to 1100 kg/cm 2 . When ethylidene diacetate is the product, it can then be decomposed to produce vinyl acetate and acetic acid by well-known techniques. Since one mole of acetic acid is also produced in the synthesis of the diacetate, the invention makes possible an overall process for the production of vinyl acetate which produces acetic acid rather than consumes it.

摘要:Alkylidene diesters such as ethylidene diacetate are selectively produced in high yields by reacting an ether and/or an ester under substantially anhydrous conditions with carbon monoxide and hydrogen in contact with a catalyst system comprising a rhodium compound, a halogen component, a palladium cocatalyst and a promoter component which is an agent for liberation of carboxylic acid anions. The process is carried out in the liquid phase in a solvent comprising a carboxylic acid at a temperature in the range of 150 DEG to 190 DEG C. and at a carbon monoxide partial pressure in the range from about 1.0 to 1100 kg/cm2 and a carbon monoxide/hydrogen mole ratio of 6:1 to 1:2 for the ester reaction and 10:1 to 1:2 for the ether reaction. When ethylidene diacetate is the product, it can then be decomposed to produce vinyl acetate and acetic acid by well-known techniques. Since one mole of acetic acid is also produced in the synthesis of the diacetate, the invention makes possible an overall process for the production of vinyl acetate which produces acetic acid rather than consumes it.
