摘　　要：实验以甲醛、环酮、丙酮、胺为原料,经曼尼希反应合成一种酸化缓蚀剂HSJ-3.讨论了单体配比、反应温度、反应时间、及pH值等对缓蚀剂的影响,最佳反应条件为:单体配比为2∶0.6∶1.4∶1,反应温度85 ℃,反应时间5 h,pH值为1.0～2.0.将缓蚀剂HSJ-3按标准SY/T 5405-1996在不同温度的盐酸溶液中进行评价,发现其缓蚀效果较好;在土酸中也具有较好的缓蚀效果,其效果均能达到石油天然气行业标准的要求.Because of the existence of acids,the pipelines and equipment tend to corrode.So,corrosion inhibitors are used to suppress the corrosion.In this work,formaldehyde,ketones,acetone and amine were used to synthesize an acid corrosion inhibitor HSJ-3 through the Mannich reaction.The optimum reaction conditions were found as follows:monomer ratio of formaldehyde,ketones,acetone and amine =2:0.6:1.4:1,reaction temperature 85℃,reaction time 5 h and pH 1.0 - 2.0.HSJ-3 inhibitor has a better inhibition effect in hydrochloric acid at 90℃,120℃and 150℃.It also has good corrosion inhibition effect in mud acid which meets the requirements of oil and gas industry standards.
