Temperature-resistant diesel oil emulsifying additive

Abstract

The invention relates to the technical field of surfactants, particularly to a temperature-resistant diesel oil emulsifying additive, which comprises the following raw materials by weight: 15-23 partsof sorbitan mono oleyl ester, 6-12 parts of polyoxyethylene sorbitan monooleate, 3-6 parts of alkylphenol polyoxyethylene ether, 8-12 parts of nonylphenol polyoxyethylene ether, 10-20 parts of fattyalcohol polyoxyethylene ether, 5-10 parts of fatty acid ester, 2-5 parts of glyceryl monostearate, 8-13 parts of dioxane, 8-10 parts of tetrahydrofuran, 10-15 parts of acetone, and 13-18 parts of methanol. According to the present invention, the emulsifier prepared based on the formula has good stability, can restore a good emulsified state by slightly stirring even if long-term placement, and canbe added with a certain corrosion inhibitor according to different water qualities of each place so as to 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 temperature-resistant diesel emulsifying additive. Background technique

[0002] Emulsifier is a substance that can improve the surface tension between the various constituent phases in the emulsion to form a uniform and stable dispersion system or emulsion. Emulsifier is a surface active substance with both hydrophilic and lipophilic groups in the molecule. The base, which gathers on 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 in diesel preparations have poor surface activity and poor interfacial tension, which cannot meet the growing demand for use. Contents of the invention

[0004] In order to overcome the existing above-mentioned shortcomings, the present invention provides a temperature-resistant diesel emulsifyi...
