根据国标GT/B 5096铜片腐蚀试验法测定生物柴油的腐蚀等级,并对主要腐蚀组分试验。测量生物柴油的硫含量和水溶性酸或碱,再结合酸值,分析造成腐蚀性主要原因。结果表明：生物柴油的硫含量、水溶性酸和酸值因素都会对金属腐蚀有影响,并且生物柴油中的低级脂肪酸是造成金属腐蚀的主要原因。

According to GT/B 5096,the corrosion graduate of biodiesel with the test method on Cu corrosion and the main corrosion components were determined.The reason of corrosion by testing the sulfur content and water soluble acid or alkali,plus the acid value were analyzed.It turned out that the sulfur content,water soluble acid and acid value influenced on mental corrosion,and short chain fatty acids in biodiesel was the main cause of mental corrosion.
