本文将ＳｎＣｌ_４与Ｄ００１离子交换树脂上的磺酸基团发生络合反应，形成Ｈ_０≤－１１．３５，且不会被阳离子交换而失活的新的酸中心，从而使Ｄ００１·Ｓｎ树脂的酸催化活性明显提高。以乙酸和正丁醇的液相酯化反应为模型，Ｄ００１·Ｓｎ催化剂能使该反应在试验条件下的表观活化能从１１１．０ｋＪ／ｍｏｌ降低到３９．０ｋＪ／ｍｏｌ。在连续分水的最佳反应条件下，乙酸丁酯５ｈ产率可达９８．７％，优于等当量Ｈ_２ＳＯ_４的催化活性，有良好的工业应用性能。
In this paper, SnCl_4 and D001 ion exchange resin sulfonic acid groups complexation reaction to form H_0≤-11.35, and will not be cation exchange inactivation of the new acid center, so D001 · Sn resin acid Catalytic activity was significantly improved. Taking the esterification of acetic acid and n-butanol as the model, D001 · Sn catalyst can reduce the apparent activation energy of the reaction from 111.0kJ / mol to 39.0kJ / mol under the experimental conditions. Under the optimal reaction conditions of continuous water division, the yield of butyl acetate 5h can reach 98.7%, which is better than the catalytic activity of equivalent H 2 SO 4 and has good industrial application performance.
