摘要

研究了异构十四醇聚氧乙烯醚磷酸酯的合成工艺,并探讨产品在防锈涂料中的应用。具体研究内容及结果如下:1.以正庚醇为原料,通过格尔伯特方法,反应合成异构十四醇。探讨最佳工艺条件并测定其羟值242. 13。2.以异构十四醇和环氧乙烷为原料,在碱性条件下反应生成异构十四醇聚氧乙烯醚[C_(14)H_(29)O(CH_2CH_2O)_7H]。3.以异构十四醇醚和五氧化二磷为原料,研究异构十四醇醚磷酸酯最佳反应条件,测得其表面张力26. 87 mN/m,CMC 0. 25 g/L,HLB值10. 86,产品与液体石蜡混合后下层分出10 mL水平均所需时间540 s,与异构十三醇醚磷酸酯相比,表面性能更优。4.最适宜用作乳液聚合的是碳数14、乙氧基数7的乳化剂。并将其应用于防锈乳液漆制备,测试表明其耐水性、耐盐水性、耐冲击性等均优,达到了预计效果,有望代替进口异构十三醇醚磷酸酯的使用。
        The synthesis process of isomeric tetradecanol polyoxyethylene ether phosphate is explored,and the application of the product in antirust coating is discussed. The specific research items and results are as follows: 1. The n-heptanol is used as raw material to synthesize the isomeric tetradecanol by the Guerbet method. The optimum process is investigated and the hydroxyl value is determined to be 242. 13. 2. The isomeric tetradecanol and ethylene oxide are used as raw materials to react under alkaline conditions to form the isopropanol polyoxyethylene ether(C_(14)H_(29)O(CH_2CH_2O)_7H). 3. The isomeric tetradecyl ether and phosphorus pentoxide are used as raw materials to explore the optimal reaction conditions of the isomeric tetradecanol ether phosphate. The surface tension is 26. 87 mN/m,CMC is 0. 25 g/L and HLB value is10. 86. The product is mixed with liquid paraffin and the time for separation of the lower layer with 10 mL of water is 540 s. Compared with the isomeric tridecyl ether phosphate,the surface performance is better. 4. The most suitable emulsifier for emulsion polymerization has a carbon number of 14 and an ethoxy number of 7. It is applied in the preparation of antirust emulsion paint. The test result shows that the water resistance,salt water resistance and impact resistance of the cured film are excellent. It is expected to replace the imported isomeric tridecyl ether phosphate.
