Adding inhibitors into raw materials is an important method of inhibiting coke formation. Phosphorus ester-drewamine salt is an important coke inhibitor. In this study, phosphate was synthesized with phosphoric acid and iso-octanol, catalyzed by activated aluminum oxide, activated sodium sulfate and tungsten phosphoric acid. It is shown that tungsten phosphoric acid as catalyst gives the best results because of its high catalytic performance. The reaction conditions were shown to have a great effect on the yield of target product. The experiment results indicate that the optimum conditions are as follows: tungsten phosphate content of 5.0%, tungsten phosphoric acid as the catalyst, catalyst dosage of 2.0%, iso-octanol and acid molar ratio of 2.3, and the reaction time of 4 hours. The yield of phosphate was found to be 72.8% under the above conditions. IR spectra analysis shows that the product is indeed the target product phosphate., authors=null, authorsList=null, authorCompany=null, correspAuthors=null, authorNote=null, correspAuthorsNote=null,

articleAbstract=乙烯裂解生产过程中存在的一个突出问题是结焦，在裂解原料中添加抑制剂是抑制结焦的一种重要方法，磷酸二异辛酯的吗啉盐是一种新型的结焦抑制剂。本实验以磷酸和异辛醇为原料，分别以活性氧化铝、活性硫酸钠、钨磷酸为催化剂，合成磷酸二异辛酯。通过改变催化剂的种类，选择催化性能良好的杂多酸钨磷酸为催化剂。实验结果表明，反应条件对目标产物收率有很大影响，钨磷酸含量为5%，催化剂用量为原料质量的2.0%，异辛醇与磷酸的物质的量之比为2.3，反应时间为4h时，磷酸二异辛酯收率最高，达72.8%。IR谱图分析结果表明产物为目标产物磷酸二异辛酯。,
