摘要
文中以实验室合成的Q[n](n=5～8)与一定浓度的硫酸作用,形成瓜环硫酸盐晶体。运用酸碱滴定法,对该产物的酸度进行测定,通过计算得出不同瓜环的缚酸比例,进而总结出瓜环缚酸的规律。另采用该瓜环硫酸盐催化环己醇合成环己烯,既减少硫酸用量,降低了实验操作的危险性和实验室污染,又增加了瓜环的应用范围。对催化剂用量、反应时间对产率的影响进行了研究,收到了较满意的效果。
This article synthesizes a series of Cucurbit[n]urils Sulphates with different cucurbit[n]urils and sulfuric acid in some certain concentration.Acid-base titration is used to measure the acidity of product,through calculations,the percentage of the sulfuric acid and cucurbit[n]urils in the product is gained,and the regular pattern about the interaction between cucurbit[n]urils and sulfuric acid can be obtained.Synthesis of cyclohexene was introduced.This reaction was catalyzed by cucurbit[n]urils sulfate,the danger of operation and environmental pollution were decreased and the application of cucurbit[n]urils was broadened.These factors like reaction time and the amount of catalyst were researched,and the satisfied results were obtained.
