响应面优化法研究花椒籽油在近临界水中的水解

Optimization of hydrolysis of prickly ash seed oil in near critical water by response surface methodology

利用响应面法对花椒籽油在近临界水中水解的反应条件进行了优化。以水解转化率为考察指标,根据Box-Benhnken的中心组合试验设计原理对试验进行设计和结果分析。研究了温度、时间和水油体积比对反应的联合影响,得出最佳工艺条件为:反应温度241.1℃,反应时间4.94 h,水油体积比2.95∶1。在此条件下,花椒籽油水解转化率接近100%。

The hydrolysis of prickly ash seed oil in near critical water was studied . The conversion rate was used as an index, the combined effects of temperature, time and water - oil ratio were investigated and optimized using RSM. The optimum conditions were as follows： reaction temperature 241.1℃, reaction time 4, 94 h,water-oil ratio 2.95： 1. Under the conditions the conversion rate was close to 100%.
