| titleOfInvention | Lubricating oil pour point depressant copolymerized by soybean oil and acrylic ester and preparation method thereof |
| abstract | A lubricating oil pour point depressant copolymerized with soybean oil and acrylates, the chemical formula of the obtained polymer is shown as formula (I) or formula (II): firstly, putting soybean oil, acrylic ester, a Salen-Cu-salicylaldehyde catalyst and refined toluene which is subjected to reflux drying and reduced pressure distillation by using sodium metal into a polymerization reaction tube, vacuumizing and filling nitrogen on a Schlenk device, and stirring to obtain a uniformly mixed solution; step two, connecting the solution obtained in the step one to a Schlenk device, vacuumizing and filling nitrogen, and injecting a toluene solution of AIBN or BPO during the last nitrogen filling to obtain a uniform solution; step three, placing the solution obtained in the step two in a constant-temperature oil bath pan, pouring the solution into cold methanol after the reaction is finished, and precipitating; filtering the filtrate, and drying the obtained filter residue in vacuum to obtain a polymer which can be used as a pour point depressant for the lubricating oil; has the characteristics of excellent performance and simple and feasible method. |
