Embodiment 1

[0030] (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 1. 50ml of toluene is heated up to 60°C to completely dissolve myristyl alcohol in toluene, then quickly add 0.254g of catalyst p-toluenesulfonic acid into the three-necked flask, and heat up to 110-120°C for 5 hours. When the amount of water in the water separator is equivalent to the theoretical value, the system is in a light yellow transparent liquid state, and the reaction is 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 washed with a 5% NaOH solution to remove p-toluenesulfonic acid and unreacted methyl alcohol. Acrylic acid generally needs to be washed 3-4 times u...

Embodiment 2

[0034]The difference from Example 1 is that the 21.44g tetradecyl alcohol (0.1mol), the 0.254g catalyst p-toluenesulfonic acid added in the step (1) are replaced by adding 24.24g cetyl alcohol, 0.277g catalyst p-toluenesulfonic acid, The 14.13g (0.05mol) tetradecyl methacrylate, 0.18g benzoyl peroxide added in the step (2) were replaced by adding 15.53g (0.05mol) hexadecyl methacrylate, 0.184g benzoyl peroxide .

Embodiment 3

[0036] The difference from Example 1 is that the 21.44g tetradecyl alcohol (0.1mol), 0.254g catalyst p-toluenesulfonic acid added in the step (1) are replaced by adding 27.05g octadecyl alcohol, 0.299g catalyst p-toluenesulfonic acid, The 14.13g (0.05mol) tetradecyl methacrylate, 0.18g benzoyl peroxide added in the step (2) were replaced by adding 16.9g (0.05mol) octadecyl methacrylate, 0.198g benzoyl peroxide .

Abstract

The invention relates to a nitrogen-containing ternary polymer biodiesel pour point depressant, a preparation method and application thereof. The preparation method comprises the following steps of: 1) respectively preparing methacrylic acid high-carbon ester and N-hexadecyl methacrylamide; and 2) adding methacrylic acid high-carbon ester, N-hexadecyl methacrylamide and vinyl acetate into a solvent, then adding an initiator, and carrying out polymerization reaction to obtain a methacrylic acid high-carbon ester-N-hexadecyl methacrylamide-vinyl acetate ternary polymer, i.e., the nitrogen-containing ternary polymer biodiesel pour point depressant. Compared with the prior art, the nitrogen-containing ternary polymer biodiesel pour point depressant solves the problem of poor broad spectrum ofa single methacrylic acid pour point depressant, the N-hexadecyl methacrylamide and the vinyl acetate are introduced to expand the composition of the pour point depressant, the pour point depression effect is improved, and the pour point depressant is simple in preparation process and convenient in experimental operation.

Description

technical field [0001] The invention belongs to the technical field of biodiesel pour point depressants, and relates to a nitrogen-containing ternary polymer biodiesel pour point depressant and its preparation method and application, which are used to improve the low-temperature flow performance of biodiesel. Background technique [0002] Biodiesel is currently recognized at home and abroad as one of the most competitive green and renewable substitutes for petrochemical diesel. Especially for my country, the development of biodiesel industry can effectively promote China's rural and economic and social development, and has very important strategic significance for the adjustment of my country's agricultural structure, energy security and comprehensive management of the ecological environment. At present, there have been many reports abroad about the development prospects of biodiesel, optimization of preparation methods, combustion emissions, safety and non-toxicity, environ...
