• Esterification of free fatty acids (Biodiesel) using nano sulfated-titania as catalyst in solvent-free conditions

  日期：2013.3

  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.

  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。
