In organic chemistry, hydroformylation, also known as oxo synthesis or oxo process, is an industrial process for the production of aldehydes (R−CH=O) from alkenes (R2C=CR2). This chemical reaction entails the net addition of a formyl group (−CHO) and a hydrogen atom to a carbon-carbon double bond. This process has undergone continuous growth since its invention: production cap… Web14 apr. 2024 · 1 上海化工研究院有限公司吴泾分公司 上海 200241 Wujing Branch of Shanghai Research Institute of Chemical Industry Co., Ltd., Shanghai 200241, China 2 上海煤基多联产工程技术研究中心 上海 200241 Shanghai Coal-Based Polygeneration Engineering Technology Research Center, Shanghai 200241, China 3 华东理工大学 上 … Web25 nov. 2024 · It describes the main catalyst synthesis methods, provides data on hydroformylation of unsaturated compounds (including asymmetric hydroformylation), and shows how those compounds can be used.
