Embodiment 1

[0019] Embodiment 1: Take 10 grams of waste oil for removing impurities, add 1 g of maleic anhydride powder, under the protection of nitrogen, first heat the waste oil to 70-80 ° C, then add maleic anhydride, until the maleic anhydride dissolves completely, heat up to 195°C, stirred and reacted for 2 hours, then cooled to 150°C, added 8g of diethanolamine, heated to 165°C, stirred and reacted for 2 hours, after cooling, 17.5g of viscous liquid product was obtained, which was detected by Essentia LC-15C high performance liquid chromatography The product contains maleic acid diethanolamide, maleic linoleic acid diethanolamide, fatty acid diethanolamide, glycerol and unreacted diethanolamine. Sampling was prepared to prepare 0.5%, 1%, and 1.5% aqueous solutions respectively. Test the anti-rust performance; the anti-rust grades of the three solutions are 3, 2, and 1 respectively.

Embodiment 2

[0020] Example 2: Take 8 grams of waste oil for removal of impurities, add 1 g of maleic anhydride, heat and dissolve under nitrogen protection, the dissolution steps are the same as above, until the maleic anhydride is completely dissolved, heat up to 200 ° C, stir for 1.5 hours, cool to 150 ° C, Add 12g of diethanolamine, heat to 170°C, stir and react for 2 hours, and get 19.3g of viscous liquid product after cooling; take samples to prepare 0.5%, 1%, and 1.5% aqueous solutions respectively, and test the antirust performance; the antirust properties of the three solutions The grades are grade 1, grade 0 and grade 0 respectively.

Embodiment 3

[0021] Example 3: Take 90 grams of decontaminated waste oil, add 10 g of maleic anhydride, heat and dissolve under nitrogen protection, and dissolve the same steps as above. After the maleic anhydride is completely dissolved, heat up to 195 ° C, stir for 1 hour, cool to 150 ° C, add 104g of diethanolamine, heated to 165°C, stirred and reacted for 4 hours, after cooling, 194g of viscous liquid product was obtained, and samples were prepared to prepare 0.5%, 1%, and 1.5% aqueous solutions respectively to test the antirust performance; the antirust grades of the three solutions were respectively Level 2, Level 0, Level 0.

Abstract

The invention relates to the technical field of drainage oil utilization, and particularly discloses a method for producing an antirust agent by using drainage oil. The drainage oil firstly reacts with maleic anhydride to obtain maleate drainage oil and then reacts with alcohol amine to generate maleate drainage oil acid alcohol amide. The method has the advantages that the used raw material drainage oil is recovered oil in swillings, a new application field is created for application of the drainage oil, the adopted reaction conditions are mild, the technological operation is convenient, the production cost is low, and the obtained maleate drainage oil acid alcohol amide has excellent anti-rust property, can be applied to products of a cutting fluid, anti-rust water and the like as an anti-rust agent.

Description

technical field [0001] The invention relates to the technical field of waste oil utilization, and specifically discloses a method for producing an antirust agent by using waste oil. Background technique [0002] Waste oil is a general term for all kinds of low-quality oil in people's daily life. It can be divided into three categories: one is gutter oil in a narrow sense, that is, the greasy floating matter in the sewer or the oil that is simply processed and extracted from leftovers and leftovers (commonly known as swill) in hotels and hotels; The oil produced after the offal and pigskin processing and refining; the third is the oil used for frying food after it has been used more than a certain number of times, and then it is reused or re-used after adding some new oil to it. Waste oil comes from a wide range of sources. It is estimated that there are about 2-3 million tons of waste oil in my country every year. Because waste oil does not have a good application path, it...
