摘要：NOVELTY - A diesel low-temperature flow improver comprises (in weight parts) amide (1-5), polyethylene-vinyl acetate copolymer (1-5) and a surfactant (1-5), and an esterification and salinization product of edetic acid such as aminotriacetic acid and cannabidiolic acid. USE - Diesel low-temperature flow improver. ADVANTAGE - The improver can be directly compounded with polyethylene-vinyl acetate to form an excellent diesel pour point depressant. The improver can be prepared easily using a quick reaction while removing catalyst and recycling the catalyst and solvent so as to increase yield rate. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for a method for preparing a diesel low temperature flow improver, which involves carrying out amidation, esterification and salinization of edetic acid. Polyethylene-vinyl acetate and surfactant are added and a mixture is stirred. The mixture is heated at 100-120 degrees C, and stirred for 1-3 hours. The mixture is cooled and packaged.
