Abstract: Exploitation and research of compositive product, i.e. Corrosion Inhibitor, was carried out by the mixing of the main component of corrosion inhibitor with surfactants, chelate, organic amine and liquid of prefabrication, then the optimal proportion was found out in order to build the best matching systems. The models among the anti-corrosive capacity of the inhibitor and operation conditions were established by polynary quadratic regression. The optimum operation conditions obtained by non-linear programming (NLP) are the following: the amount of the surfactants, chelate, organic amine and the liquid of prefabrication is 0.112 6, 0.010 2, 0.213 9 and 0.357 2 respectively. The verified experiment showed that the products under the optimum operation conditions had the better water-soluble capablity, slower corrosion rate and higher anti-corrosive capacity (up to over 99%).

摘要： 利用正交实验方法对复配缓蚀剂进行了开发与研究，以环烷酸和多乙烯多胺合成的缓蚀剂为主要成份，再与表面活性剂、螯合物、有机胺和自制液进行复配而得；采用多元二次回归方程式对合成产物腐蚀速率与操作[CM(49*2]因素的关系进行回归；用非线性规化确定出实验范围内腐蚀速率最小的适宜复配操作条件：表面活性剂用量为[CM)]0.112 6（与合成缓蚀剂的质量比，下同），螯合剂用量为0.010 2，有机胺用量为0.213 9，自制液用量为0.357 2。验证实验结果表明，在最适宜的实验配比下所得产品其水溶性好、腐蚀速率慢、缓蚀率高达99%以上。
