摘　　要：用马来酸酐、丙烯酸及次亚磷酸钠合成了一种磷基马来酸-丙烯酸共聚物缓蚀剂DZ-1,并采用正交试验方法研究了合成该缓蚀剂的最佳条件。红外光谱分析表明合成产物与实验设计的相符。合成缓蚀剂在缓速酸中有较好的缓蚀效果,添加0.5%KI及0.2%非离子表面活性剂的DZ-1在90℃下对缓速酸的缓蚀率可达到99.95%。maleiacid-acrylicopolymeinhibitoDZ-1 wasynthesized with maleianhydride, acryliacid and sodium phosphite phosphorus, and using the orthogonal experimenmethod to study the optimum condition fosynthesiof the corrosion inhibitor. Infrared spectrum analysishowthathe synthetiproduciin conformity with experimental design. Synthesiof corrosion inhibitohagood corrosion effectin the retarded acid, and when 0.5% KI and 0.2% of non-ionisurfactantare added in DZ-1, the corrosion rate can reach 99.95% in retarded acid unde90 ℃.
