摘要:通过浸渍和高温氢还原制备了pd基双金属催化剂.采用 Xrd,Tem,Hr-Tem 和 Xps 对新制备的催化剂进行了表征,并在烯烃瓦克氧化反应体系中进行了评价.在新型催化剂存在下,在叔丁基过氧化氢(tbhp)和空气的协同氧化作用下,一系列烯烃被氧化为相应的酮.还通过催化剂回收和热过滤测试研究了催化剂的稳定性和反应体系的非均质性.催化剂的性能与pd和cu之间以及金属和载体之间的相互作用相关. Tbhp和空气的协同效应在反应中得到证实.在所开发的体系中实现了烯烃(包括芳基烯烃和环烯烃)的瓦克型氧化.低碳烯烃和环烷烃的收率有待提高.

标 题:Process for the preparation of alpha-oximinoalkyl ketones
发明人：DORLARS ALFONS
权利人:BAYER AG
摘要:Alpha -Oximino ketones, for example, oximinodipropyl ketone, are prepared by reacting a ketone in an inert organic solvent immiscible with water in the presence of a hydrogen halide with an amount of alkyl nitrite that is insufficient for complete nitrosation followed by extracting the ketone formed with an aqueous alkali solution, removing the alkaline extract formed and isolating the Alpha -oximino ketone. The ketones formed are useful as intermediates in the synthesis of pharmaceutical compounds, dyes, analytical reagents, plant protection agents, and optical brighteners.

摘要:An industrial preparation of aldehydes and/or alcohols from olefins of more than 3 carbon atoms by a catalytic hydroformylation of the olefin reactant at a pressure of from 50 to 1000 bar and a temperature of from 50 to 180° C. in the presence of an uncomplexed rhodium catalyst homogeneously dissolved in the reaction medium. The catalytic activity of the rhodium is maintained, first by extracting it from the initially discharged reaction mixture by means of an aqueous solution of a nitrogen-containing complexing agent such as sulfonated or carboxylated pyridines, quinolines or the like. In a recycle of the complexed rhodium to be reused in the hydroformylation reaction, the aqueous rhodium-containing extract is fed to a precarbonylation stage where it subjected to a required precarbonylation in the presence of an essentially water-insoluble organic liquid and in the presence of carbon monoxide, synthesis gas or another gas mixture containing carbon monoxide at from 50 to 1000 bar and from 50 to 180° C. The mixture discharged from this precarbonylation stage is then separated into an organic phase containing the main part of the rhodium and an aqueous phase containing the complexing agent. The resulting rhodium-containing organic phase with the regenerated catalyst is then fed into the hydroformylation stage to complete its recycle.
