Embodiment 1

[0026] Put 1,000 kg of fatty acid, 500 kg of urea, and 1,000 kg of ethanol into a urea-coated kettle, stir and heat to 80-85°C and leave it for 1.5 hours, put it into a crystallization box to crystallize; cool with cold water, and the temperature of the material drops to 20-22°C For 24 hours, the crystallized material was subjected to vacuum filtration; the liquid phase was poured into the mixed liquid storage tank, and the mixed liquid was evaporated in a long tube. The evaporation temperature of the long tube was 105°C. Purified fatty acid; the solid phase is urea package to recover saturated fatty acid; the purified fatty acid (acid type antiwear agent crude product) after washing is vacuum dehydrated and filtered to become the finished acid type diesel antiwear agent.

[0027] The main fatty acid composition of gained product is as follows:

[0028] Raw fatty acid composition: C 16 : 0-3.2%; C 18 : 0-0.9%; C 18 : 1-34.8%; C 18 : 2-56.2%; C 18 : 3-4.4%.

Abstract

The invention discloses a diesel oil anti-wear agent. The diesel oil anti-wear agent is prepared from fatty acid, urea and ethanol in a mass ratio of 10: (4.8-5): 10 through purification of the fatty acid. The saturated fatty acid content of the diesel oil anti-wear agent disclosed by the invention is less than 2%, the yield of a product is more than 80%, the condensation point of the product is less than -12 DEG C, the cloud point of the product is less than -8 DEG C, the acid value of the product is 190, and the diesel oil anti-wear agent has good low-temperature stability, greatly improves the lubricity of diesel oil, reduces the wear degree of an oil injection pump, prolongs the service life of an engine, does not corrode metal and has good compatibility with diesel oil.

Description

technical field [0001] The invention belongs to the field of lubricating materials, and relates to a diesel antiwear agent and a preparation method thereof. Background technique [0002] With the widespread use of diesel engines, the consumption of diesel is increasing year by year. However, a large amount of diesel consumption will inevitably lead to further aggravation of harmful emissions from vehicles. Due to the serious impact of emissions on the ecological environment, human health and economic development, governments of various countries have successively formulated strict emission regulations to limit the harmful emissions of diesel vehicles. With the implementation of National IV and National V standards for diesel, the sulfur content of diesel will drop below 10PPM. Desulfurized diesel has been implemented in domestic refineries. At present, domestic sulfur reduction technologies such as hydrotreating and hydrocracking are adopted to make fuel oil contain sulfur ...
