以油茶籽油生产的副产物油茶籽壳为原料,用硫酸催化水解的方法,制备有机化工产品糠醛,研究了该制备工艺中硫酸溶液的浓度、用量以及催化反应温度3个单因素对糠醛产量的影响,在单因素试验的基础上,利用3因素3水平响应面分析法（RSM）建立二次回归模型,对3因素优化组合,找到最适生产糠醛的条件。同时,对回归模型中的各因素和因素间的交互作用进行方差分析,从而确定了油茶籽壳制备糠醛的最佳工艺为硫酸溶液浓度2 mol/L、用量230 m L、催化反应温度155℃。在最佳工艺条件下,对优化的试验结果验证显示糠醛的实际平均浓度为0.137 mol/L,与回归分析所得的理论值比较吻合。

Using the camellia seed shell to prepare furfural by means of sulfuric acid catalyzed hydrolysis reaction. And having studied the influence of the three single factors including the sulfuric acid solution concentration, the sulfuric acid solution dosage and the catalytic reaction temperature on the yield of furfural, on the basis of single factor experiments, the quadratic regression model was established by 4-variable, 3-level RSM. Then the combination of the three factors was optimized so as to find the optimum conditions, at the same time, A...
