研究了生物柴油与0~#柴油以不同比例混合后的铜片腐蚀情况,分析了生物柴油的腐蚀原因.结果表明:不同原料制备的生物柴油与不同比例的混合柴油,铜片腐蚀情况略有不同,当以地沟油为原料制备的生物柴油掺入比例超过50%时,其铜片腐蚀不合格;以其它油脂为原料制备的生物柴油以任何比例掺入0~#柴油中,其铜片腐蚀均能满足要求.生物柴油的腐蚀主要是低级脂肪酸腐蚀.

Researches are carried out on the copper stain test of the mixture with different proportion of bio-diesel and 0~# diesel, and the corrosion causes are analyzed. The results show that the corrosion situation of copper is slight different using biodiesel prepared by different raw material and mixed with different proportion of diesel. The corrosion of copper is unqualified using biodiesel prepared by the material of waste oil, whose mixed ratio is more than 50%.The corrosion of copper is qualified using the 0~# diesel mixed with biodiesel prepared by the raw material of other fat. The corrosion of biodiesel is mainly due to lower fatty acid.
