标题:一种β-巯基羧酸化合物的制备方法
摘要:本发明提供了一种β‑巯基羧酸化合物的制备方法,所采用的固体碱催化剂具有合适的碱强度,既可保证硫化氢被活化,促进反应的进行,又可抑制原料或产品中的羧基与活性位的结合,避免活性位慢慢失活.同时,固体碱催化剂选择多羟基化合物作载体,载体表面的大量羟基可促进硫化氢在反应体系中的溶解及在催化剂表面的吸附,进而迁移至活性位周围被活化,保证在较低压力中,反应仍可达到高转化率和高选择性,并且,催化稳定性较优.另外,本发明的反应条件温和,在低温低压下进行气液相反应,易于工业化应用.实验表明,本发明得到的β‑巯基羧酸化合物的反应转化率均不低于98%,选择性不低于88%.经1000H连续评价,催化稳定性较优.
