Embodiment 1

[0027] Add 2 parts of dipropylene glycol methyl ether with a molecular weight of 500 and 2 parts of N,N-diethylethylamine into tetrahydrofuran, and slowly add 2 parts of acryloyl chloride dropwise under nitrogen protection at a temperature of 0°C; after 1 hour, the temperature Rise to room temperature and continue the reaction for 12h. After the reaction, the precipitate produced by the reaction was filtered off; the product in the filtrate was washed out with petroleum ether.

[0028] Then, 5 parts of the above-mentioned product and 5 parts of polyethyleneimine (molecular weight: 1800) were dissolved in methanol. After reacting for 20 hours, after stopping the reaction, the reaction product was first rotatably evaporated to remove part of the solvent, and the concentrated product was precipitated in petroleum ether, centrifuged and dried to obtain the solvent.

Embodiment 2

[0030] Add 5 parts of dipropylene glycol methyl ether with a molecular weight of 5000 and 5 parts of N,N-diethylethylamine into tetrahydrofuran, and slowly add 5 parts of acryloyl chloride dropwise under nitrogen protection at a temperature of 0°C; after 1 hour, the temperature Rise to room temperature and continue the reaction for 12h. After the reaction, the precipitate produced by the reaction was filtered off; the product in the filtrate was washed out with petroleum ether.

[0031] Then, 15 parts of the above-mentioned product and 20 parts of polyethyleneimine (molecular weight: 1800) were dissolved in methanol, and the reactants were subjected to freeze-thaw-freeze-thaw cycle treatment under airtight conditions, and stirred simultaneously at 40°C. After reacting for 20 hours, after stopping the reaction, the reaction product was first rotatably evaporated to remove part of the solvent, and the concentrated product was precipitated in petroleum ether, centrifuged and drie...

Embodiment 3

[0033] Add 3 parts of dipropylene glycol methyl ether and 3 parts of N,N-diethylethylamine to tetrahydrofuran, and slowly add 2 parts of acryloyl chloride dropwise under nitrogen protection at a temperature of 0°C; after 1 hour, raise the temperature to room temperature, Continue to react for 12h, after the reaction finishes, filter the precipitate produced by the reaction; wash out the product in the filtrate with sherwood oil;

[0034] Then, 8 parts of the above product and 10 parts of polyethyleneimine were dissolved in methanol, and the reactants were subjected to freeze-thaw-freeze-thaw cycles under airtight conditions, and then stirred at 42°C for 20 hours to stop the reaction. Finally, the reaction product was first rotatably evaporated to remove part of the solvent, and the concentrated product was precipitated in petroleum ether, centrifuged and dried to obtain the solvent;

Abstract

The invention discloses a preparing method of an auxiliary additive beneficial for oil transport. The method includes the steps of adding dipropylene glycol methyl ether and N,N-diethylethanamine to tetrahydrofuran, slowly dropwise adding acryloyl chloride, raising the temperature to the room temperature 1 hour later, continuing the reaction for 12 hours, filtering out precipitates generated in reaction after the reaction ends, washing out a product in filtrate through petroleum ether, dissolving 4-10 parts of the product and 5-20 parts of polyethylene imine in methyl alcohol for stirring reaction for 20 hours, conducting rotary evaporating on the reaction product after the reaction stops to remove part of the solvent, settling out the concentrated product from the petroleum ether, conducting centrifuging and drying to obtain a solvent, and adding the solvent and mica powder to deionized water to be ball-milled to prepare suspension, namely the auxiliary additive.

Description

technical field [0001] The application relates to the technical field of organic chemistry, in particular, to a method for preparing an auxiliary additive for oil transportation. Background technique [0002] According to statistics, at present, my country consumes about 22 million tons of oil every year, of which 15% and about 3.3 million tons become waste oil. At present, there are three main methods for the comprehensive utilization of waste oil in my country: one is to simply process and purify waste oil, and directly use it as low-grade industrial oleic acid, stearic acid, and industrial oil; the other is to use waste oil to prepare phosphorus-free laundry detergent. powder; the third is to produce biodiesel (fatty acid methyl ester) by alcoholysis of waste oil. [0003] Although waste oil has been comprehensively utilized, the transportation of waste oil is still a difficult problem. [0004] Waste oil will contain triglycerides, alkanes, alkenes, low-carbon fatty aci...
