三间磺酸钠三苯基膦乙酰丙酮羰基铑的合成及其催化性能研究
Synthesis of Rh(acac)(CO)(TPPTS) and study of its catalytic performance
采用乙酰丙酮二羰基铑作为金属前体、三间磺酸钠三苯基膦为配体合成了三间磺酸钠三苯基膦乙酰丙酮羰基铑。通过优化反应溶剂以及重结晶用溶剂,单批次合成产物148.70 g,收率93%。利用FT-IR、NMR和元素分析等表征手段对产物进行表征,表明产品纯度符合要求。优化的合成方法在提升产物收率及纯度的同时减少了溶剂的使用量,适用于大规模合成生产。经催化丙烯氢甲酰化测试表明,所合成的产品与常用工业催化剂三(三间磺酸钠三苯基膦)羰基氢化铑活性近似,适合作为催化剂应用于氢甲酰化第四代催化工艺。
Rh(acac)(CO)(TPPTS) is synthesized via using (acetylacetonato)dicarbonylrhodium as the metal precursor and sodium 3,3',3″-phosphanetriyltribenzenesulfonate (TPPTS) as the ligand.Through optimizing the solvents for reaction and recrystallization,148.70 g of product is prepared in one batch,with a yield of 93%.The prepared product is characterized by means of FT-IR,NMR and elemental analysis,showing that the purity of the product meets the requirement.The synthesis method optimized in this study improves the yield and purity of the product while reduces the usage of solvent,which is suitable for large-scale production.The prepared Rh(acac)(CO)(TPPTS) is served for propylene hydroformylation,exhibiting a comparable catalytic activity to that of HRh(CO)(TPPTS)3,a commonly used industrial catalyst,suggesting Rh(acac)(CO)(TPPTS) a suitable catalyst for two-phase hydroformylation.
