- 摘要:
- 以大豆油和甲醇为原料,KOH为催化剂,采用响应面法对大豆油甲酯合成工艺进行优化。在单因素试验的基础上,以反应物醇油摩尔比、催化剂用量、反应温度、反应时间为影响因素,大豆油甲酯的产率为响应值,进行响应面分析。结果表明大豆油甲酯的最佳合成条件为:醇油摩尔比为5.5∶1,催化剂用量为大豆油质量的1.08%,反应温度为61.6℃,反应时间为60 min。此条件下大豆油甲酯的产率为94.02%,与模型预测值基本一致。大豆油甲酯的一些性能接近矿物油,以其部分或全部取代矿物油制备环保型大豆油墨具有极大的潜力。
- Abstract:
- The systhesis of soybean oil methyl ester, from soybean oil and methanol with KOH as catalyst, was optimized by response surface methodology(RSM). Based on the single-factor testing results, methanol to oil molar ratio, catalyst amount, reaction temperature, reaction time were optimized by RSM using methyl ester yield as the response variable. The results indicated that the optimum condition that provided the highest yield were determined as follows: Methanol to oil molar 5.5∶1, catalyst amount 1.08%, reaction temperature 61.6℃, and reaction time 60 min. Under these conditions, the yield of methyl esters was 94.02%, consisted with the predicted value. Some of the properties of soybean oil methyl ester were close to mineral oil, which had great potential to produce environmentally and friendly soybean oil ink with some or all of the mineral oil.
