Problems solved by technology

[0003] In recent years, domestic oil refineries have begun to use hydrotreating to produce low-sulfur diesel oil to meet environmental protection requirements. The subsequent decrease in the lubricity of low-sulfur diesel oil has caused wear and damage to fuel pumps in diesel engines.

Embodiment 1

[0017] 1. Preparation of ricinoleic acid monoglyceride: add 50kg ricinoleic acid and 10kg glycerol to the reaction kettle, then add 3kg solvent oil, and add 1kg of concentrated sulfuric acid with a mass concentration of 98% as a catalyst, and remove water under reflux After 5-6 hours, after the esterification reaction, the resulting material is washed with water to remove the acidic catalyst, and finally the material is dehydrated by vacuum distillation to obtain ricinoleic acid monoglyceride.

[0018] 2. Compounding: first add 30kg ricinoleic acid into the reaction kettle, heat up to 100-110°C, keep for 1 hour to remove the water, then cool down to below 50°C, add 70kg ricinoleic acid monoglyceride, stir well and serve as diesel anti-wear agent.

Embodiment 2

[0020] 1. Preparation of ricinoleic acid monoglyceride: 50kg ricinoleic acid and 11kg glycerol are added to the reaction kettle, then 3.3kg solvent oil is added, and 0.9kg mass concentration of 98% concentrated sulfuric acid is added as a catalyst. Remove water for 5-6 hours, after the esterification reaction, wash the resulting material with water to remove the acidic catalyst, and finally distill under reduced pressure to dehydrate the material to obtain ricinoleic acid monoglyceride.

[0021] 2. Compounding: firstly add 30kg ricinoleic acid into the reaction kettle, raise the temperature to 100-110°C, keep for 1 hour to remove the water, then cool down to below 50°C, add 68kg ricinoleic acid monoglyceride, stir well and serve as diesel anti-wear agent.

Embodiment 3

[0023] 1. Preparation of ricinoleic acid monoglyceride: 52kg ricinoleic acid and 9.5kg glycerol are added to the reaction kettle, then 2.8kg solvent oil is added, and 1kg mass concentration is added as 98% concentrated sulfuric acid as a catalyst, under reflux state Remove water for 5-6 hours, after the esterification reaction, wash the resulting material with water to remove the acidic catalyst, and finally distill under reduced pressure to dehydrate the material to obtain ricinoleic acid monoglyceride.

[0024] 2. Compounding: First add 31kg ricinoleic acid into the reaction kettle, heat up to 100-110°C, keep for 1 hour to remove the water, then cool to below 50°C, add 72kg ricinoleic acid monoglyceride, stir well and serve as diesel anti-wear agent.

Abstract

The invention discloses a diesel anti-wear agent. The diesel anti-wear agent is prepared by taking ricinoleic acid, propanetriol and solvent oil as raw materials. A preparation method of the diesel anti-wear agent disclosed by the invention comprises the following steps: (1) preparing ricinoleic acid monoglyceride: firstly adding the ricinoleic acid and the propanetriol into a reaction kettle, further adding the solvent oil, adding a catalyst for performing esterification reaction, stirring, increasing the temperature to 160-180 DEG C, removing water for 5-6h under a reflux state, washing a generated material with the water for removing the acidic catalyst after the end of the esterification reaction, and finally performing decompression distillation to dehydrate the material so as to get the ricinoleic acid monoglyceride; and (2) compounding: firstly adding ricinoleic acid into the reaction kettle, increasing the temperature to 100-110 DEG C, keeping for 1h, removing the water, then cooling to below 50 DEG C, adding ricinoleic acid monoglyceride, and uniformly stirring to get the diesel anti-wear agent. The diesel anti-wear agent disclosed by the invention has the advantages of reducing the emission of harmful substances, protecting an environment and greatly improving the lubricating performance of diesel.

Description

technical field [0001] The invention relates to a fuel additive, in particular to a diesel antiwear agent. 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. Therefore, further reducing the fuel consumption and pollution of diesel vehicles is an urgent problem to be solved at present. Among the many solutions, the method of using diesel additives can achieve energy saving and clean emission by changing the physical properties of the fuel without changing the vehicle and engine structure or adding equipment. [0003] In recent ye...
