用生物柴油来制备环氧生物柴油,然后在D001树脂的催化作用下,环氧生物柴油和异辛醇进行异构醚化开环反应,合成的改性生物柴油即为润滑油基础油。通过红外光谱对原料和产物的结构进行表征,并对合成的润滑油基础油的性能与环氧生物柴油和150SN矿物润滑油进行了比较。结果表明,所合成的润滑油基础油热稳定性好、黏温性能好、黏度指数大、氧化稳定性良好、承载能力和抗磨性能较好。同时考察了D001树脂重复使用性,发现重复使用5次后仍具有较高催化活性。
The epoxidized biodiesel(EBD) was prepared with biodiesel(BD) as raw material,w hich was then subjected an etherification ring opening reaction with 2-ethyl hexanol over the D001 resin catalyst; the resultant product can be used as the lubricant base stock. The products and material used were characterized by FT-IR and TG; the properties of as synthesized lubricant base stock were compared with those of EBD and the lubricant from 150 SN mineral oil. The results showed that the as-synthesized lubricant base stock is excellent in terms of thermal stability,viscosity-temperature behavior,viscosity index,oxidation stability,and wear resistance and loading capacity. Moreover,D001 resin as a catalyst exhibits good reusability; it remains high active after being used for five times.
