Embodiment 1
[0037] A PMA-based diesel pour point depressant containing 3-benzoyl ethyl acrylate is formed by polymerization of tetradecyl methacrylate and 3-benzoyl ethyl acrylate, and its preparation method is as follows:
[0038] (1) 21.44g and 10.33g of tetradecanol and methacrylic acid were weighed respectively according to the molar ratio of tetradecanol and methacrylic acid 1:1.2, and were added to a dry and clean three-necked flask, and 45mL of toluene was added as a solvent at the same time. The three-necked flask with the reactants was moved to an oil bath and heated and stirred to fully dissolve, and then the polymerization inhibitor hydroquinone and catalyst p-toluenesulfonic acid were added to the three-necked flask and fully dissolved, wherein hydroquinone and p-toluenesulfonic acid were fully dissolved. Toluenesulfonic acid was 0.6% and 1.2% of the total mass of the reactants, respectively. The temperature was raised to 80°C for 2h of pre-reaction. After the pre-reaction, the...
Embodiment 2
[0044] The difference between the preparation process of this example and Example 1 is that in step (2), 4.24 g of tetradecyl methacrylate, 1.02 g of ethyl 3-benzoyl acrylate (tetradecyl methacrylate and 3-benzyl methacrylate) were added. The molar ratio of acyl ethyl acrylate was 3:1), and the mass of the initiator benzoyl peroxide dissolved in 10 mL of toluene was 0.0526 g.
Embodiment 3
[0046] The difference between the preparation process of this example and Example 1 is that in step (2), 5.65g of tetradecyl methacrylate, 0.68g of ethyl 3-benzoyl acrylate (tetradecyl methacrylate and 3-benzyl methacrylate) were added. The molar ratio of acyl ethyl acrylate was 6:1), and the mass of the initiator benzoyl peroxide dissolved in 10 mL of toluene was 0.0633 g.
