用于获得支链醛的烯烃加氢醛化方法
摘要：
本发明技术涉及对烯丙醇加氢醛化制4‑羟基丁醛和2‑甲基‑3‑羟基丙醛的方法，该方法包括(i)将烯丙醇与CO和H2混合，形成原料混合物；以及(ii)使原料混合物在催化剂存在下，在能够形成包括4‑羟基丁醛和2‑甲基‑3‑羟基丙醛的产物混合物的条件下进行反应，其中催化剂是过渡金属络合物，其包括过渡金属离子和咬合角为约70°至约100°的二膦配体，并且其中产物混合物中的4‑羟基丁醛与2‑甲基‑3‑羟基丙醛的比率小于1.5:1。
摘要（英）：

The present technology relates to methods of hydroformylating allyl alcohol to 4-hydroxybutanal and 2-methyl-3-hydroxypropanal, comprising (i) admixing allyl alcohol with CO and H2 to form a starting material mixture, and (ii) reacting the starting material mixture in the presence of a catalyst under conditions capable of forming a product mixture comprising 4-hydroxybutanal and 2-methyl-3-hydroxypropanal, wherein the catalyst is a transition metal complex comprising a transition metal ion and a diphosphine ligand with a bite angle from about 70° to about 100°, and wherein the ratio of 4-hydroxybutanal to 2-methyl-3-hydroxypropanal in the product mixture is less than 1.5:1.
