The kinetics and mechanism of the formation of phthalate mono-esters and phthalate di-esters from phthalic anhydride and a variety of mono- and di-hydric alcohols are reported and discussed. The kinetic work is extended to a mechanistic study of the same reactions using titanium tetra-n-butoxide and tri-n-butyltin ethoxide as catalysts. The results support a mechanism involving alkoxy ligand exchange at the metal as a crucial step in the catalysis.
报告并讨论了邻苯二甲酸酐与多种一元和二元醇生成邻苯二甲酸单酯和邻苯二甲酸双酯的动力学和机制。动力学研究扩展到使用四正丁氧钛和三正丁基锡乙氧基作为催化剂的同类反应的机理研究。结果支持一种机制,即金属表面的烷氧基配体交换作为催化中的关键步骤。
