Abstract

The invention relates to a lubricity additive of low-sulfur diesel oil and a preparation method thereof, the invention is characterized in that the addictive is unsaturated fatty acid glyceride, wherein the unsaturated fatty acid glyceride is a mixture of monoglyceride, diglycerideoleic and triglyceride of oleic acid or linoleic acid. the method comprises the following steps: taking plant oil as a raw material, preparing fatty acid ester by using plant oil and alcohol under the condition of base catalysis, performing the processes of vacuum rectification and urea adduction fractionation to fatty acid ester, acquiring nonsaturated fatty acid ester and etherifying nonsaturated the fatty acid ester and glycerin under the base-catalyzed condition to obtain the product. The invention provides a novel production process of monoglyceride, diglycerideoleic and triglyceride of unsaturated fatty acid. The process takes plant oil (especially non-edible plant oil) as the raw material, no harmful substance is discharged in the process of production, so that the method has the advantages of easy raw material acquisition and no pollution. The product can be taken as a lubricity additive of low-sulfur diesel oil, the lubrication performance and physical properties is equal or better than that of a foreign same kind product.

Description

technical field [0001] The invention belongs to the field of organic synthesis, and in particular relates to a lubricity additive for low-sulfur diesel oil and a preparation method thereof. Background technique [0002] With the development of the economy, energy consumption is increasing. Environmental pollution caused by harmful gas emissions from energy consumption is also becoming more and more serious. Therefore, various countries in the world have enacted strict regulations to limit harmful gas emissions. As one of the most important engine fuels, diesel oil has strict restrictions on the content of harmful substances in order to reduce the harmful gas components after combustion. Among them, in order to reduce the emission of sulfide gas, in the 1980s, Western countries began to produce low-sulfur diesel, thereby strictly restricting the use of high-sulfur diesel. It is generally required that the sulfur content be lower than 500ug / g (500ppm). Some countries and r...
