Hydroformylation of Lower Olefins and the Use of Oxo Synthesis Products Based on C4–C5 Aldehydes in the Production of Ester Lubricating Oils. Part 2. Rhodium Processes Developped in LLC «RN-RD Center»
摘要
R-Oxo hydroformylation processes on rhodium phosphite complexes developed at LLC «RN-RD CENTER» are described – selective production of n-butyral from propylene (R-Oxo I), production of a mixture of n-butyral and isobutyral in equal parts (R-Oxo II), selective production of n-pentanal from a mixture of linear butenes (R-Oxo III). A scheme for the hydroformylation of propylene with membrane separation of the catalyst from the heavy reaction products is described.The analysis of the direction of using C3–C5 oxosynthesis products as raw materials for the production of ester lubricants is carried out.
