摘  要:
研究了用改良硫酸法从油茶壳中提取糠醛的工艺。在单因素试验的基础上,运用Box-Behnken中心组合试验和响应面法考察了液料比、水解反应时间、水解反应温度3个因素对糠醛提取率的影响,并优化了提取工艺。结果表明,最佳工艺条件为:液料比5.96 mL/g;水解反应时间3.33 h;水解反应温度140℃。在此条件下,糠醛提取率的预测值为1.78%,验证试验值为1.93%,说明响应面法优化油茶壳中提取糠醛的工艺可行。

摘  要:
Furfural extracted from Camellia oleifera Abel nutshell using modified sulfuric acid as the catalyst was studied.Based on single factor tests of liquid-solid ratio,hydrolysis reaction time,reaction temperature and sulfuric acid mass fraction,the optimum extraction process was evaluated by Box-Behnken central composite experimental design and response surface methodology analysis.The results indicated that the optimum conditions were liquid-solid ratio of 5.96 mL/g,hydrolysis reaction time of 3.33 h and reaction temperature of 140℃.Under these optimized conditions,the experimental value of furfural extraction yield was 1.93%,in good agreement with the predictive value 1.78%.Therefore,the furfural extraction process from Camellia oleifera Abel nutshell optimized by response surface methodology is very reliable.
