Embodiment 1

[0012] Take 50 parts by weight of ricinoleic acid, 20 parts of diglycerin, 10 parts of sulfuric acid, 5 parts of magnesium stearate and 1 part of calcium sulfonate, pour them into the reaction kettle, and heat the reaction kettle to 70~80°C with a water bath , continue to stir for 2-6 hours, then lower to room temperature, then heat the reactor to 80°C by heating with a water bath again, and keep stirring for 12-24 hours.

Embodiment 2

[0014] Take 80 parts by weight of ricinoleic acid, 40 parts of diglycerin, 20 parts of sulfuric acid, 10 parts of magnesium stearate and 5 parts of calcium sulfonate, pour them into the reaction kettle, and heat the reaction kettle to 70~80°C with a water bath , continue to stir for 2-6 hours, then lower to room temperature, then heat the reactor to 80°C by heating with a water bath again, and keep stirring for 12-24 hours.

Embodiment 3

[0016] Take 60 parts by weight of ricinoleic acid, 30 parts of diglycerin, 15 parts of sulfuric acid, 8 parts of magnesium stearate and 3 parts of calcium sulfonate, pour them into the reaction kettle, and heat the reaction kettle to 70~80°C with a water bath , continue to stir for 2-6 hours, then lower to room temperature, then heat the reactor to 80°C by heating with a water bath again, and keep stirring for 12-24 hours.

Abstract

The invention discloses a diesel oil lubricity improver. The diesel oil lubricity improver is characterized by containing the following ingredients in parts by weight: 50-80 parts of ricinoleic acid, 20-40 parts of diglycerol, 10-20 parts of sulfuric acid, 5-10 parts of magnesium stearate and 1-5 parts of calcium sulfonate. Compared with the traditional technologies, the diesel oil lubricity improver has the advantages that the problem that a filter screen is blocked up due to too high acid value due to the fact that plant oleic acid is used singly in the past is solved, meanwhile, the emission of harmful substances is reduced, the environment is protected, and the lubricating property of the improver is improved greatly.

Description

technical field [0001] The invention belongs to the field of chemical industry, and in particular relates to a diesel lubricity improver and a preparation method thereof. Background technique [0002] Due to the generally used harsh hydrogenation process in the production of clean diesel oil, the content of polar compounds in clean diesel oil is reduced, and the content of polycyclic and bicyclic aromatic hydrocarbons is correspondingly reduced, thus reducing the natural lubricating performance of diesel oil and causing fuel injection pump failure. Wear occurs, reducing its service life. [0003] At present, my country's diesel is mainly composed of straight-run diesel, full-fraction hydrogenated diesel, diesel hydrogenated diesel, and a small amount of medium-pressure hydrogenated diesel. Diesel oil retains some polar lubricating components, but its sulfur content is about 0.2%, which cannot meet the requirements of social sustainable circular economy development. Conten...
