Problems solved by technology

[0004] The present invention aims at many problems existing in the diesel oil lubricity improver in the petrochemical industry, and provides an environment-friendly diesel lubricity improver, which can significantly improve the diesel lubricity after being added to diesel oil, which is mainly composed of alcohol compounds and fatty acids in the catalyst It is obtained by reaction under the catalysis of the improver. After using this improver, it can prevent excessive wear of precision parts of the engine, poor atomization of diesel oil, insufficient engine power and other problems caused by poor lubricity. It has anti-high pressure, anti-friction, and reduces the emission of harmful substances , energy saving and environmental protection can better improve the lubricity of diesel oil and increase the service life of the engine, etc.

Embodiment 1

[0021] Synthesis of fatty acid monoester and fatty acid diester mixture: Add 28.25g oleic acid, 18.6g ethylene glycol, 0.4g p-toluenesulfonic acid to start stirring in sequence in a reactor with a thermometer, condenser, and stirrer, and pass into Nitrogen, gradually increase the temperature to 120-150°C, and distill the water generated by the reaction at this temperature, react for 4-5 hours, stop the reaction if no water evaporates, cool to room temperature and let it stand until the product settles and separates , the obtained upper product is the target product, and the esterification rate of fatty acid is 97.3%.

Embodiment 2

[0023] The synthesis of fatty acid monoester and fatty acid diester mixture: add 28.25g oleic acid, 30.44g propylene glycol, 0.43g p-toluenesulfonic acid to start stirring successively in the reactor that has thermometer, condensing tube, stirrer, and pass into nitrogen, Gradually raise the temperature to 80-120°C, and distill the water generated by the reaction at this temperature, and react for 3-6 hours. If no water is evaporated, stop the reaction, cool to room temperature and stand still. After the product settles and separates, you can get The upper layer product is exactly target product, and the esterification rate of fatty acid is 98.2%.

Embodiment 3

[0025] Synthesis of fatty acid monoester and fatty acid diester mixture: add 28.04g linoleic acid, 27.03g butanediol, 0.46g p-toluenesulfonic acid successively in the reactor with thermometer, condenser, stirrer to start stirring, and pass Enter nitrogen, gradually raise the temperature to 140-150°C, and distill the water generated by the reaction at this temperature, and react for 4-5 hours. If no water evaporates, stop the reaction, cool to room temperature and let it stand until the product settles and separates. Finally, the upper product obtained is the target product, and the esterification rate of fatty acid is 96.9%.

Abstract

The invention relates to the technical field of chemical engineering, in particular to an environment-friendly diesel oil lubricity improving agent. After the diesel oil lubricity improving agent is added into diesel oil, lubricity of the diesel oil can be obviously improved. The diesel oil lubricity improving agent is obtained by alcohols and fatty acids under a catalytic reaction. After the diesel oil lubricity improving agent is used, the problems that poor lubricity leads to excessive abrasion of precision parts of an engine, poor atomization of the diesel oil, insufficiency of power of the engine, and the like can be solved. The diesel oil lubricity improving agent has the advantages of being resistant to high pressure and resistant to friction, reducing discharging hazardous substances, being energy-saving, environment-friendly, and capable of well improving lubricity of the diesel oil and prolonging the service life of the engine, and the like.

Description

technical field [0001] The invention relates to the technical field of chemical industry, and relates to an environment-friendly diesel lubricity improver which can significantly improve the lubricity of diesel after being added to diesel. Background technique [0002] With the development of the economy and the requirements of environmental protection, the application of diesel engines will be more and more. Now diesel engines are mainly used in trucks in developing countries, and diesel engines are also used in passenger cars in many developed countries. Therefore, the demand for diesel as an energy-saving fuel continues to increase, but the sulfur content in diesel is strictly controlled for environmental protection, but in the desulfurization process, the natural polar compounds with lubricating properties that originally existed in the oil It is also removed, which leads to a decrease in the lubricating performance of low-sulfur diesel oil, which leads to the gradual ex...
