[0017] The synthetic method of polysulfone polyamine composite oil product antistatic agent of the present invention comprises the following steps:
[0018] (1) Add C12 olefins, xylene, and methyl acrylate into a pressure-resistant container according to the mass ratio of 1.0:0.7-0.9:0.2-0.3, continuously feed sulfur dioxide and react under ultraviolet light, relative to each mole of C12 olefins Add 0.05-0.07 mol of initiator azobisisobutyronitrile, and seal the reaction at 6-10°C for 18-20 hours. After the reaction is completed, directly import the reaction solution into the lye tank for SO2 removal operation to obtain the main component of polysulfone ;
[0019] (2) Mix xylene, epichlorohydrin and isopropanol solvent at a mass ratio of 1:0.4-0.6:0.1-0.2, and after heating to 55-65°C, add 0.8- 1.2mol of N-tallow-1,3-propylenediamine, kept at 60-65℃ for 4h, then added 0.8-1.2mol of N-tallow-1,3-propylenediamine, heated to 80- React at 85°C for 4 hours, then add 0.15-0.25mol ...
Embodiment 1
[0031] Synthesis of the main component of polysulfone: add 1 mol of C 12 olefin, 0.7 mol of xylene solvent, and 0.2 mol of methyl acrylate into a pressure-resistant flask, continuously pass sulfur dioxide into it, add 0.05 mol of initiator azobisisobutyronitrile, and Seal the reaction for 20 hours, open the bottle cap, release the unreacted sulfur dioxide, and the crude product is a yellowish viscous liquid.
[0032] Synthesis of the main component of polyamine: Add 0.4 mol of epichlorohydrin to a four-neck flask equipped with a reflux condenser, dropping funnel, and temperature control device, and use 1 mol of xylene and 0.1 mol of isopropanol as the reaction solvent. Heat the mixture to 60°C, add 0.8mol of N-tallow-1,3-propylenediamine, keep it at 60-65°C for 4h, then add 0.8mol of N-tallowyl-1,3-propylenediamine Amine, heat up to 80°C for 4 hours, then add 0.15mol of sodium hydroxide per mol of epichlorohydrin, heat up to 90-95°C for 3-4 hours, then add 0.15mol of sodium hy...

[0038] Synthesis of the main component of polysulfone: add 1 mol of C 12 olefin, 0.8 mol of xylene solvent, and 0.25 mol of methyl acrylate into a pressure-resistant flask, continuously pass sulfur dioxide into it, add 0.06 mol of initiator azobisisobutyronitrile, and Seal the reaction for 20 hours, open the bottle cap, release the unreacted sulfur dioxide, and the crude product is a yellowish viscous liquid.
[0039] Synthesis of the main component of polyamine: Add 0.5 mol of epichlorohydrin into a four-neck flask equipped with a reflux condenser, dropping funnel, and temperature control device, and use 1 mol of xylene and 0.15 mol of isopropanol as the reaction solvent. Heat the mixture to 60°C and add 1.0mol of N-tallow-1,3-propylenediamine, keep it at 60-65°C for 4h, then add 1.0mol of N-tallowyl-1,3-propylenediamine Amine, heat up to 80°C for 4 hours, then add 0.2mol of sodium hydroxide per mol of epichlorohydrin, heat up to 90-95°C for 3-4 hours, then add 0.2mol of sodi...
