Embodiment 1

[0033] A preparation method of ternary polymer biodiesel pour point depressant, the specific steps are:

[0034] (1) Add 10.33g (0.12mol) of methacrylic acid, 21.44g of tetradecyl alcohol (0.1mol), and 0.192g of hydroquinone to a three-necked flask equipped with a condenser, a water separator, a thermometer, and a magnetic stirring device , 50ml of toluene, heat up to 60°C to completely dissolve methacrylic acid and myristyl alcohol in toluene, then quickly add 0.254g of catalyst p-toluenesulfonic acid into the three-necked flask, heat up to 110-120°C to react for 5 Hours, when observing that the amount of water in the water separator was equivalent to the theoretical value, the system was in the light yellow transparent liquid state, and the reaction was terminated. After the reaction was completed, the obtained reaction solution was distilled under reduced pressure, and then alkali washing and water washing were carried out after removing the solvent. The alkali washing was ...

Embodiment 2

[0037] Difference with Example 1 is that in step (1), add 21.44g tetradecyl alcohol (0.1mol), 0.254g catalyzer p-toluenesulfonic acid to change into adding 24.24g cetyl alcohol, 0.277g catalyzer p-toluenesulfonic acid, step ( 2) Add 14.13 g (0.05 mol) of tetradecyl methacrylate and 0.17 g of benzoyl peroxide into 15.53 g (0.05 mol) of hexadecyl methacrylate and 0.184 g of benzoyl peroxide. NMR characterization of the product cetyl methacrylate-benzyl methacrylate-N-vinylpyrrolidone terpolymer image 3 shown.

Embodiment 3

[0039]Difference with embodiment 1 is that in step (1), add 21.44g tetradecyl alcohol (0.1mol), 0.254g catalyzer p-toluenesulfonic acid to change into adding 27.05g octadecyl alcohol, 0.299g catalyzer p-toluenesulfonic acid, step ( 2) Add 14.13 g (0.05 mol) of tetradecyl methacrylate and 0.17 g of benzoyl peroxide into 16.9 g (0.05 mol) of octadecyl methacrylate and 0.198 g of benzoyl peroxide. NMR characterization of the product stearyl methacrylate-benzyl methacrylate-N-vinylpyrrolidone terpolymer Figure 4 shown.

Abstract

The present invention provides a kind of preparation method of ternary polymer biodiesel pour point depressant, it is characterized in that, comprising: high carbon methacrylate, benzyl methacrylate and N-vinylpyrrolidone are dissolved in solvent, in A polymerization reaction occurs under the action of an initiator to obtain a ternary polymer biodiesel pour point depressant. The raw material of the ternary polymer of the present invention is cheap and easy to obtain, the synthesis method is simple, not only has strong oil solubility, but also can effectively improve the low-temperature fluidity of biodiesel, and has a good effect in reducing the condensation point and the cold filter point, It provides new possibilities for the research and development of new biodiesel.

Description

technical field [0001] The invention relates to a ternary polymer biodiesel pour point depressant, its preparation and application, and belongs to the technical field of biodiesel pour point depressants. Background technique [0002] Biodiesel is a mixed long-chain fatty acid ester produced by transesterification of various animal and vegetable oils, cooking oils, etc., with low-carbon alcohols. As a substitute for diesel, biodiesel has similar properties to petrochemical diesel, can be used directly in diesel engines, does not need to modify the engine, and has the advantages of regeneration, cleanliness and safety. In recent years, more and more scientific research institutions and energy companies have invested in the research of biodiesel, and gradually realized large-scale production and application. It is easy to precipitate and crystallize under low temperature conditions, resulting in poor fluidity at low temperatures and clogging the engine, which hinders the promo...
