摘要
以苯甲酸、三乙烯四胺为原料合成了咪唑啉中间体,采用氯化苄对其改性来制备咪唑啉季铵盐缓蚀剂,实验得出最优合成条件是:n(苯甲酸)/n(三乙烯四胺)=2︰1.3;酰化温度为150～160℃;环化温度210～220℃,环化时间2 h。红外光谱图证明该实验成功地合成了咪唑啉季铵盐缓蚀剂。并通过失重法在2%HCl介质中研究了该缓蚀剂对碳钢的缓蚀性能,缓蚀率达到96.3%。
A kind of imidazoline quaternary-ammonium-salt was synthesized from benzoic acid, triethylenete tramine and benzyl chloride. The suitable conditions were obtained through tests： n （benzyl acid）/n （triethylenete tramine and benzyl chloride） was 2 ： 1.3, acylating temperature was 150~160 ℃, reaction temperature and reaction time of cycling was 210-220 ℃ and 2 h respectively. The IR spectrum chart proved that the imidazoline quaternary-ammonium-salt was synthesized successfully. The anti-corrosion performance of the compound on mild steel was investigated in 2% HC1 by the weight loss method.
