| Abstract: | The synthesis and using conditions of esterified copolymer of maleic anhydride and vinyl acetate (ESMVA) as pour-point depressant for diesel fuels were investigated. ESMVA was produced by using Maleic a hydride, vinyl acetate and 1-tetradecyl alcohol as raw materials, benzene and toluene as solvents, azobisisobutyronitrile (AIBN) as initiator, p-toluene sulfuric-acid as catalyst, at 138°C, for 6h. It was used in 10 diesel samples. PP(Pour-Point) of 0# diesel from Jinzhou Refinery was lowered by 14～23°Cand CFPP(Cold Filter Plugging Point) 2～4°C, PP of 0# diesel from Yanshan Refinery 16～30°C and CFPP 2°C. Depression mechanism of ESMVA was discussed. |
