Abstract

Fatty amides have been successfully synthesized from palm olein and urea by a one-step lipase catalyzed reaction. The use of immobilized lipase as the catalyst for the preparation reaction provides an easy isolation of the enzyme from the products and other components in the reaction mixture. The fatty amides were characterized using Fourier transform infrared (FTIR) spectroscopy, proton nuclear magnetic resonance ((1)H NMR) technique and elemental analysis. The highest conversion percentage (96%) was obtained when the process was carried out for 36 hours using urea to palm oil ratio of 5.2: 1.0 at 40 degrees C. The method employed offers several advantages such as renewable and abundant of the raw material, simple reaction procedure, environmentally friendly process and high yield of the product.

摘要

通过一步脂肪酶催化反应，已成功从棕榈油精和尿素合成了脂肪酰胺。使用固定化脂肪酶作为制备反应的催化剂，便于从反应混合物中的产物和其他成分中分离出酶。使用傅里叶变换红外光谱（FTIR）、质子核磁共振（¹H NMR）技术和元素分析对脂肪酰胺进行了表征。当在40℃下使用尿素与棕榈油的比例为5.2:1.0进行该过程36小时时，获得了最高转化率（96%）。所采用的方法具有几个优点，如原料可再生且丰富、反应程序简单、环境友好且产物收率高。
