摘　　要：文章研究了用硫酸催化合成α-甲基丙烯酸十六酯的合成工艺条件及应用情况。α-甲基丙烯酸与十六醇的摩尔比为1.3∶1,对苯二酚0.4%,浓硫酸0.56%,偶氮二异丁腈用量是酯的4.6%;恒温70～80℃,聚合8h。使用1g/L的α-甲基丙烯酸十六酯可使河南濮阳0#柴油冷滤点降低6℃,凝点降低7℃;南阳0#柴油冷滤点降低5℃,凝点降低8℃;濮阳-10#柴油冷滤点降低5℃,凝点降低6℃。In the paper, using sulfuric acid catalyzed synthesis of 16 α-methyl acrylic acid ester synthesis conditions and application, α-methyl acrylic acid and 16 alcohol molar ratio of 1.3 ： 1, Hydroquinone 0.4 %, concentrated sulfuric acid 0.56 %. The amount of azobisisobutyronitrile used was 4.6 % of the amount of ester; temperature at 70- 80 ℃, and aggregation 8h. The use of 1 g/L of α-methyl acrylic acid ester 16 can reduce the cold filter plugging point of Henan Puyang 0# diesel oil by 6 ℃, reduce the pour point by 7 ℃, reduce the cold filter plugging point of Nanyang 0# diesel oil by 5 ℃, reduce the pour point by 8 ℃, Puyang -10 # diesel oil to reduce the cold filter plugging point 5 ℃. Freezing point lowering 6 ℃.
