两相催化1-十二烯氢甲酰化反应中混合胶束的作用研究

Studies on Effect of Mixed Micelles on 1-Dodecene Hydroformylation in Biphasic Catalytic System

研究了 Rh Cl(CO) (TPPTS) 2 催化 1-十二烯氢甲酰化反应中 ,十六烷基三甲基溴化铵 (CTAB)与十二烷基硫酸钠 (SDS)形成的混合胶束对反应的促进作用 .研究结果表明 ,随 SDS在混合表面活性剂溶液中比例的增大 ,1-十二烯生成醛的转化率先增大后又降低 。

The mixed micelles formed by CTAB and SDS have an obvious catalytic effect on 1\|dodecene hydroformylation in biphasic catalytic system which is more effective than the single micelle of CTAB when the concentration of SDS is low. It is proved that with the increase of the concentration of SDS in the mixed micelles , the conversion of 1\|dodecene hydfroformylation increases at the beginning, and then declines. The catalytic effect has a clear optimum point. These results were discussed.
