本文研究了两相催化体系中,在CTAB(C_(16)H_(33)NMe_3Br)存在下,水溶性铑-膦配合物RhCl(CO)(TPPTS)_2对1-己烯氢甲酰化反应的催化性能,详细考察了反应温度、压力、膦/铑比等对催化活性的影响。结果表明,在1.0MPa恒压下,反应温度100℃,膦/铑摩尔比为16,H_2:CO=1:1的条件下,1-己烯氢甲酰化的转化频率(TOF)可达到39.8min ̄(-1)。在此反应条件下,有机相和水相容易分离,铑-膦配合物流失到有机相中的量极小。
In this paper, we studied the hydroformylation of 1-hexene with water-soluble rhodium-phosphine complex (RhPc) (TPPTS) 2 in the presence of CTAB (C_ (16) H_ (33) NMe_3Br) The effects of reaction temperature, pressure, phosphine / rhodium ratio on the catalytic activity were investigated in detail. The results showed that the conversion frequency (TOF) of 1-hexene hydroformylation under the condition of constant pressure of 1.0MPa, reaction temperature of 100 ℃, molar ratio of phosphine to rhodium of 16 and H 2: CO = 1: 1 Reaching 39.8 min ~ (-1). Under this reaction conditions, the organic and aqueous phases are easily separated and the amount of rhodium-phosphine complex lost to the organic phase is extremely small.
