This work selected and characterized compositions and properties of three types of fatty acid⁃based and three types of fatty acid ester⁃based antiwear agents. Using hydrogenated diesel oil from Hebei Zhongjie Petrochemical Group Co.Ltd as testing model, the lubrication property and anti⁃emulsification capability of six types of antiwear agents were investigated. The results indicate that lubrication property gradually increases with the increasing content of antiwear agent. Monoglyceride antiwear agent shows the best lubrication property. The attrite speckle diameter of model diesel oil reduces from 734 μm to 345 μm, when the volume of Ester⁃type antiwear agent E is 200 mg/kg. Ester⁃type antiwear agent G has lower film formation capability and lubricating property because of lacking -OH polar group. Acid⁃type antiwear agent exhibits better anti⁃emulsification capability than ester⁃type agent with -OH hydrophilic group. Meanwhile, its anti⁃emulsification capability would get worse when HLB value goes up. Mixing the two materials of acid⁃type and ester⁃type antiwear agents can improve anti⁃emulsification capability of diesel oil, but has less impact on its lubricating property whether the agents are mixed or not.

Microchemical technology is a front technology of multi⁃disciplines in chemical engineering fields. The technology core is microscale transfer and chemical reaction in microchannel reactor. The application of microchemical technology can improve resource⁃utilization efficiency for energy saving and consumption reduction, enhance security, intensification and miniaturization of the chemical process, by decreasing dispersion scale, strengthening mixing and transfer, raising control and efficiency. The technology principle, characteristics, advantage and industrial application of microchemical technology were introduced, with the aim of deepening people's understanding of the microchemical technology, and then promoting the development and application of microchemical technology.
