Abstract

Abstract In recent years, research on the epoxidation of fatty acids has attracted a great deal of attention due to the increased need for eco-friendly epoxides generated from vegetable oils. The purpose of this research is to produce bio-lubricant from optimized epoxidized oleic acid by alcoholysis with methanol, tert-butyl alcohol, and ethanolamine. Epoxidation is carried out using in situ performic acid formation under a constant temperature of 60 °C where formic acid acts as an oxygen carrier and hydrogen peroxide acts as an oxygen donor. The determination of the optimum process parameters uses one factor at a time (OFAT) method and is based on the optimized process parameters until the maximum relative conversion to oxirane of 65% is achieved. The bio-lubricants are confirmed using the Fourier Transform Infrared (FTIR) analysis and the results show that the hydroxyl group is present at 3400 cm−1 of wavenumber. A kinetic modeling is performed using the MATLAB optimization tool. After 100 iterations, the reaction rate constant based on optimized epoxidized dated palm oil production were obtained as follows: k11 = 0.4251 mol⋅L−1⋅min−1, k12 = 11.345 mol⋅L−1⋅min−1, and k2 = 0.6761 mol⋅L−1⋅min−1.
基于环氧化油酸衍生的过时棕榈油原位过酸机理生产生物润滑油
摘要近年来,由于对从植物油中提取的环保型环氧化物的需求增加,脂肪酸的环氧化研究引起了人们的广泛关注。以优化后的环氧油酸为原料,与甲醇、叔丁醇和乙醇胺醇解制备生物润滑油。在60℃的恒温条件下,甲酸作为氧载体,过氧化氢作为氧供体,使用原位形成甲酸进行环氧化。最佳工艺参数的确定采用一次一因素法(OFAT),并以优化的工艺参数为基础,直到最大相对转化率达到65%。用傅里叶变换红外(FTIR)分析证实了生物润滑剂,结果表明羟基在3400 cm−1的波数处存在。利用MATLAB优化工具进行了动力学建模。经过100次迭代,得到优化后环氧化期棕榈油产量的反应速率常数为:k11 = 0.4251 mol·L−1⋅min−1,k12 = 11.345 mol·L−1⋅min−1,k2 = 0.6761 mol·L−1⋅min−1。
