通过酯交换实验制备了以新疆产的文冠果种仁油和棉籽油为原料的两种生物柴油。采用气相色谱方法对其脂肪酸甲酯组分进行了分析；考察了两种生物柴油的部分理化性质，并与0号柴油和国外生物柴油的标准进行对比。重点分析了生物柴油中脂肪酸甲酯组分分布对其理化性能的影响。实验结果表明，文冠果种仁油无需进行脱酸预处理，而各项理化指标均达到要求，更适合制备生物柴油。
牡丹籽油超临界二氧化碳萃取工艺（Supercritical Carbon Dioxide Extraction of Paeonia suffruticosa Andr. Seed Oil）
牡丹籽油 超临界二氧化碳萃取 中心复合设计
2009/12/28
以牡丹籽为原料，利用超临界CO2萃取提取牡丹籽油。采用单因素试验对影响牡丹籽油得率的5个影响因素（筛分粒度、CO2流量、压力、温度和时间）进行考察。以油得率为响应目标，对3个主要影响因素（筛分粒度、压力和温度）运用中心复合设计法，并经响应面法优化分析得到二次多项式回归方程预测模型，确定了超临界CO2萃取牡丹籽油的最佳条件为：筛分粒度60目，CO2流量20L/h，压力35MPa，温度45℃，时间12...
