Abstract

The invention relates to the technical field of surfactants, particularly to a diesel oil micro-emulsification additive, which comprises the following raw materials by weight: 13-20 parts of sorbitanmono oleyl ester, 1-3 parts of alkylphenol polyoxyethylene ether, 8-12 parts of fatty alcohol polyoxyethylene ether, 6-10 parts of fatty acid ester, 1-5 parts of glyceryl monostearate, 12-16 parts oftetrahydrofuran, 20-25 parts of acetone, and 18-23 parts of methanol. According to the present invention, the flammable distillate naphthenic acid in the oil refining process is used as the main additive, such that the composite additive has good compatibility with diesel oil; and a small amount of the nonionic surfactant is supplemented to increase the activity of the additive, reduce the interfacial tension, and effectively improve the use efficiency of the emulsifier.

Description

technical field [0001] The invention relates to the technical field of surfactants, in particular to a diesel micro-emulsion additive. Background technique [0002] Emulsifier is a substance that can improve the surface tension between various constituent phases in an emulsion to form a uniform and stable dispersion system or emulsion. Emulsifier is a surface active substance with both hydrophilic and lipophilic molecules in the molecule The base, which accumulates at the oil / water interface, can reduce the interfacial tension and reduce the energy required to form the emulsion, thereby increasing the energy of the emulsion. [0003] The existing emulsifiers used for diesel formulations have poor surface activity and poor interfacial tension, which cannot meet the growing demand for use. SUMMARY OF THE INVENTION [0004] In order to overcome the above-mentioned deficiencies in the prior art, the present invention provides a diesel oil micro-emulsion additive. [0005] Th...
