摘　　要：Hydroformylation of 1-dodecene was studied in a biphasic systemusing water-soluble rhodium complex [RhCl(CO)(TPPTS)_2] as catalystin the presence of cetyl trimethyl ammonium bromide as surfactant toenhance the reaction rate. Efforts were devoted to improve theperformance of hydroformylation by exploring reactor configurationwhich enhanced the mixing, dispersion and interphase mass transfer.Experiments were carried out in a 0.5 L autoclave at the totalpressure of 1.1 Mpa and temperature from 363 K to 373 K.Hydroformylation of 1-dodecene was studied in a biphasic system using water-soluble rhodium complex [RhCl(CO)(TPPTS)2] as catalyst in the presence of cetyl trimethyl ammonium bromide as surfactant to enhance the reaction rate. Efforts were devoted to improve the performance of hydroformylation by exploring reactor the reaction configuration which enhanced the mixing, dispersion and interphase mass transfer. Experiments were carried out in a 0.5L autoclave at the total pressure of 1.1MPa and temperature from 363K to 373K. Several surface aeration configurations were tested, and higher hydroformylation rate with higher normal/branched aldehyde ratio produced were achieved. The experience suggest that improved reactor configuration by taking reaction engineering, measures is beneficial to better process economy in alkene hydroformylation.
