摘要/Abstract

摘要： 采用C₉馏分与丙烯酰胺为原料合成的二元共聚物AM/C₉与有机胺反应制备出一种新型曼尼希（Mannich）碱，考察了反应时间、反应温度、溶液的pH以及二甲胺与甲醛的物质的量比对产品表观黏度的影响，并利用红外光谱对其结构进行表征，最后对产品的性能进行分析。结果表明，以丙烯酰胺和C₉馏分合成的二元共聚物制备曼尼希碱的最佳反应条件为反应时间4 h、反应温度70 ℃、pH=9、二甲胺与甲醛的物质的量比1.5；红外光谱表征结果表明产品已合成，合成的曼尼希碱与聚丙烯酰胺（HPAM）比较，具有更高的增黏、耐温和耐盐性能。

Abstract: A new type Mannich base was developed by the reaction of binary copolymer AM/C₉ synthesized from C₉ petroleum fractions with acrylamide as raw materials. The effects of reaction time, reaction temperature, pH of solution and ratio of aldehyde were studied. The apparent viscosity of Mannich was characterized by IR spectroscopy and its structure is characterized. Finally, the performance of the product is analyzed. The results show that the optimum reaction conditions were as follows: The reaction time is 4 h, the reaction temperature is 70 ℃, the pH is 9 and the ratio of dimethylamine to formaldehyde was 1.5. The result of infrared spectrum characterization shows that the product has been synthesized. Synthetic Mannich base has higher viscosity, temperature and salt tolerance compared with traditional HPAM.

Key words: Mannich reaction, Apparent viscosity, Temperature and salt resistant
