摘　　要：生物柴油是天然油脂与低级醇通过酯交换反应得到的环境友好的生物质能源。本文采用红外光谱法预测了生物柴油的主要成分为脂肪酸甲酯,采用分光光度法测定了生物柴油中残留的甘油和甲醇含量分别为0.002715 g·mL^(-1)、0.09856 g·mL^(-1),采用石油产品灰分测定法测定了灰分含量为0.0032%,用石油产品运动粘度测定法测定其运动粘度为3.65 m^2·s^(-1)。Biodiesel,prepared by tranesterification of natural oil with alcohols,is an environmental friendly source of biomass energy. The constituent analysis of fatty acid methylesters in biodiesel was studied using Infrared Spectroscopy. The content of glycerol and methanol in biodiesel were determined by spectrophotometric method. The content of glycerol and methanol in biodiesel were 0. 002715 g · mL^（-1）and 0. 09856 g · mL^（-1）respectively. The ash content of biodiesel was 0. 0032%. The kinematic viscosity of biodiesel was 3. 65 m^2·s^（-1）.
