芳香酮曼尼希碱酸化缓蚀剂的合成及复配研究

摘要

37% Formaldehyde solution,acetophenone and diethylamine were chosed ultimately and these materials compounded a new type of mannich base hydrochloride acid inhibitor, and its complex research. The results showed that the best synthetic process conditions is diethylamine, formaldehyde, acetophenone molar ratio is:2:2:1 .reaction time is 8 h,reaction temperature is 80℃,,reaction system pH value is 4. Sodi-um tungstate and corrosion inhibitor have a positive synergies, potassium iodide negative synergistic effect.%以37％的甲醛溶液、苯乙酮和二乙胺为原料,合成一种新型曼尼希碱盐酸酸化缓蚀剂,并对其进行复配研究.结果表明,最佳合成条件为:二乙胺、37％甲醛溶液和苯乙酮的摩尔比为2:2:1,反应时间8h,反应温度80 ℃,pH值为4；钨酸钠和缓蚀剂有着很好的正协同效应,碘化钾与其有负协同效应.
