| 摘 要： | 以过氧化氢为氧化剂，首次尝试将夹心型杂多化合物Q12WZn3（H2O）2（ZnW9O34）2]作为催化剂应用于模型柴油的氧化脱硫．研究发现，季铵盐阳离子对夹心型杂多化合物催化剂氧化脱硫的催化活性有重要的影响；氧硫物质的量之比（O／S）和温度对反应速率有强烈的影响；二苯并噻吩上的取代基具有位阻效应，分子越大，位阻效应越大，反应活性越低．

| Abstract: | The sandwich-type heteropoly compounds Q12 is used as a catalyst for oxidative desulfurization of diesel models for the first time.The oxidation of sulfur-containing compounds in diesel is conducted using hydrogen peroxide as oxidant.It is found that the catalytic activities of the amphiphilic sandwich-type catalysts depend on the quaternary ammonium cations.The O/S ratio and reaction temperature play a vital role in the oxidative reaction.The substituent groups of dibenzothiophene show steric effect on oxidative desulfurization reaction.The reaction rate decreases with the increasing of the size of sulfur-containing compounds. |
