摘要
以脱氢枞胺为原料,采用直接缩合法合成了5种脱氢枞胺水杨醛类Sch iff碱,用IR、1H NMR确证其结构,并用静态失重法研究了它们在酸性介质中对铜的缓蚀性能。结果表明:它们对铜的缓蚀率随着Sch iff碱处理浓度的增大、成膜时间的延长、腐蚀时间的缩短而增大。脱氢枞胺(5,6二-羟基)水杨醛Sch iff碱对铜的缓蚀性能最强。
Five kinds of dehydroabietylamine salicylidene Schiff bases were synthesized by direct condensation reactions, and their structures were identified by IR and ^1H NMR. Their corrosion inhibition activity for copper was studied by static state weight loss method. The result indicated that the inhibition rate of Schiff base for copper increased with the increment of the Schiff base concentration, increment of the time of self-assemble film and decrease of corrosion time. Dehydroabietylamine 5,6-dihydroxy- salicylidene showed the best inhibition activity among these Schiff bases.
