  摘要：

  简历 纳米硫酸盐钛被测试为自由脂肪酸酯化的催化剂，特别是硬脂酸（生物柴油）的甲醇和乙醇酯化。实验设计表明，反应温度、催化剂用量和溶剂对酯转化率有正向影响。这种纳米尺寸的硫酸盐钛是通过溶胶-凝胶水热法制备的。制备的硫酸盐钛在无溶剂条件下显示出高催化活性，能直接酯化脂肪酸以及各种醇和酚的苯甲酸。这种方法因其环境友好、易于操作、高产率、操作简便和绿色特性而具有重要价值。傅里叶变换红外光谱研究表明，催化剂可在不损失催化活性的情况下重复用于酰化反应。

  An investigation on Mucor miehei lipase-catalyzed transesterifications of 16 aromatic and heteroaromatic esters in organic solvents is described. The points studied were the activity and regioselectivity of the enzyme-catalyzed reaction of either one or two ester groups situated in different positions on several heterocyclic systems with an aliphatic alcohol. The reactions took place in moderate to good yields and, in some cases, regioselectively.

  Résumé Nano sulfated titania was tested as catalyst for esterification of free fatty acids, specially methanolic and ethanolic esterification of stearic acid (biodiesels). Factorial design evidenced a positive effect of reaction temperature, amount of catalyst, and solvents on ester conversion. This nano-sized sulfated titania has been prepared by a sol-gel hydrothermal process. This prepared sulfated titania showed high catalytic activity in direct esterification of fatty acids as well as benzoic acids with various alcohols and phenols under solvent-free conditions. This method is of great value because of its environmentally benign character, easy handling, high yields, convenient operation, and green. FT-IR studies are shown that the catalyst can be reused for acylation without loss of catalytic activity.
