Embodiment 1

[0041] Take 4 parts of diethyl phthalate, 1 part of n-butylamine, 9 parts of isooctyl alcohol, and 1 part of cyclohexanone by volume and add them to the raw material mixing tank. After stirring evenly, add dodecyl methacrylate 13 parts of base esters, 30 parts of mixed fatty acid glycerides and stir evenly, then add 2 parts of phenyl propargyl ether, 8 parts of dihexadecyldimethyl ammonium chloride, stir evenly, add 2 parts of ethyl formate, Stir 14 parts of isooctyl nitrate for 30-35 minutes; add 6 parts of polyoxyethylene cetylphenol ether to the above solution, heat to 45°C-50°C, stir at 80 atmospheres for 20-30 minutes, let stand After 24 hours, filter and remove the precipitate to obtain the methanol-diesel composite additive of the present invention.

Embodiment 2

[0043] Take 2 parts of diethyl phthalate, 5 parts of n-butylamine, 3 parts of isooctyl alcohol, and 4 parts of cyclohexanone by volume and add them to the raw material mixing tank. After stirring evenly, add dodecyl methacrylate 30 parts of base esters, 20 parts of mixed fatty acid glycerides and stir evenly, then add 2 parts of phenyl propargyl ether, 4 parts of dihexadecyldimethyl ammonium chloride, stir evenly, add 8 parts of ethyl formate, Stir 10 parts of isooctyl nitrate for 30-35 minutes; add 4 parts of polyoxyethylene cetylphenol ether to the above solution, heat to 45°C-50°C, stir at 100 atmospheres for 20-30 minutes, let stand After 24 hours, filter and remove the precipitate to obtain the methanol-diesel composite additive of the present invention.

Abstract

The invention discloses a methanol diesel fuel complex additive and a preparation method thereof. The complex additive is prepared from the following raw materials in parts by volume: 1-4 parts of diethyl phthalate, 1-8 parts of n-butylamine, 1-9 parts of isooctanol, 1-6 parts of cyclohexanone, 13-42 parts of lauryl methacrylate, 7-30 parts of mixed fatty glyceride, 1-5 parts of phenyl propargyl ether, 1-8 parts of dihexadecyl dimethyl ammonium chloride, 2-12 parts of ethyl formate, 2-14 parts of isooctyl nitrate and 1-6 parts of polyoxyethylene hexadeeylalkyl ether selies. The methanol diesel fuel complex additive can enable methanol diesel fuel to be evenly mixed and to be stably stored for more than 6 months, which effectively improves the fire behaviour of the methanol diesel fuel and inhibits the volatilization when the methanol content is higher; moreover, the production process is simple and the use is convenient, thereby being beneficial to the popularization and application of the methanol diesel fuel.

Description

technical field [0001] The invention relates to a diesel oil additive, in particular to a methanol-diesel composite additive, and also relates to a preparation method of the methanol-diesel composite additive. Background technique [0002] Currently, clean alternative fuels for internal combustion engines are alcohol fuels. Alcohol fuels mainly refer to methanol and ethanol, which are easy to use, store and transport. As an alternative fuel for diesel engines, alcohol fuel has great advantages, especially for the improvement of the environment. The use of alcohol fuel in diesel engines can reduce the emission of conventional pollutants (CO, HC, NOx, PM), especially particulate matter amount, reduce smoke and carcinogenicity. The source of methanol is very rich, it can be produced from solid raw material coal, liquid raw material naphtha and residual oil, gas raw material natural gas, oil field gas and coal bed methane. my country is a country rich in coal, short of oil an...
