Study on High Effectively Supported-type Solid Acid Catalysts
摘要/Abstract
通过浸渍法和回流吸附等方法制备了多种负载型固体酸催化剂TZ1,FMSB,FMSA,FMCA,FMCB,AMCB,AMPB,FMPB,APMB和FPMB.通过乙酸酯系列酯化反应检测了催化剂的稳定性、催化活性和选择性等性能指标.实验结果表明这些固体酸催化剂对于低级脂肪酸的酯化反应具有较高的酸催化活性、选择性和稳定性.催化剂APMB重复使用10次后,其催化活性几乎不变,仍保持在95%以上,同时,对其进行了放大实验.
T hough impregnation and reflux absorption,a series of supported-typed solid acid cata-lysts were prepared,such as T Z-1,FMSB,FMSA,FMCA,FMCB, AMCB,AMPB,FMPB,APMB and FPMB.T he stability,selectivity and catalytic activation of catalysts were investigated though esterifi-cation.The results have shown that the series of catalysts have higher acid catalytic activation,stabili-ty and selectivity to lower fatty ester.After used 10 times repeatedly,the catalytic activation of APMB hardly decreases.Meanwhile,magnification-test has been finished.
