以文冠果种仁为原料,研究了文冠果种仁油的提取和生物柴油的合成一步完成的工艺。采用正交试验设计,考察了提取反应温度、石油醚液料比(mL/g)、甲醇用量(mL/g)和NaOH用量(g/g)对生物柴油得率的影响,并通过红外光谱对合成产物进行了分析。结果表明:文冠果种仁一步法合成的产物为多种脂肪酸甲酯的混合物;其最佳工艺为提取反应温度为80℃,石油醚液料比为5︰1,甲醇用量12%,NaOH用量为0.4%。在该条件下生物柴油平均得率为64.65%。 In this paper, we studied the extraction of seed kernel oil and the one-step process of the biodiesel synthesis from the seed of the seedling of Wen-huang. The effects of extraction temperature, ratio of liquid to solid (mL / g), methanol (mL / g) and NaOH (g / g) on ​​the yield of biodiesel were investigated by orthogonal experimental design. The synthetic products were analyzed. The results showed that the product of one-step synthesis of seed of X. sorghum seeds was a mixture of various fatty acid methyl esters. The optimum extraction conditions were as follows: the reaction temperature was 80 ℃, the ratio of petroleum ether to liquid was 5︰1, the amount of methanol was 12%, NaOH The amount of 0.4%. The average yield of biodiesel under this condition was 64.65%.
