Abstract

A novel green method for production of alkyls esters has been discussed in this paper. Liquid carbon dioxide (CO 2 ) can be used as reaction medium and having advantages of green solvent. Enzymatic esterification of castor oil has been carried at 1:3 stoichiometric amount of castor oil to alcohol in presence of immobilized lipase Lipozyme TL IM. The progress of the reaction has been monitored time to time and the maximum yield of 88.3% has been observed within 5 h for hexyl esters. In this process, liquid CO 2 has acted as solvent in the reaction system and has increased the mutual solubility between alcohol and castor oil. The produced hexyl esters have been evaluated for tribological properties

液态二氧化碳介质中酶法合成蓖麻油己基酯及其作为生物润滑剂的潜在应用

本文讨论了一种绿色生产烷基酯的新方法。液态二氧化碳(co2)可作为反应介质，具有绿色溶剂的优点。在固定化脂肪酶Lipozyme tlim的存在下，以化学计量量的蓖麻油与醇的比例为1:3，进行了蓖麻油的酶促酯化反应。对反应过程进行了监测，在5 h内己基酯的收率达到了88.3%。在此过程中，液态co2在反应体系中充当溶剂，提高了乙醇与蓖麻油的相互溶解度。已对所制备的己基酯进行了摩擦学性能评价
