固体超强碱Na-NaOH/γ-Al_2O_3碱性测定方法的研究

Study of base measurement of solid superbase Na-NaOH/γ-Al_2O_3

合成了一种新型固体超强碱催化剂Na-NaOH/-γA l2O3,对其碱强度、碱量进行分析。结果表明,该固体超强碱催化剂碱强度高达H-≥43,总碱量(H-≥35)达到5.3 mmol/g,在乙烯基降冰片烯(VNB)异构化为乙叉基降冰片烯(ENB)的反应中,转化率和选择性均接近100%,呈现极高的催化活性。

A new solid superbase catalyst, Na-NaOH/γ-Al2O3 Was synthesized, and analyse base strength and content of the product. The result showed that,the base strength of the product is H - ≥43 ,the all content of the product which base strength is （H - ≥35） 5.3 mmol/g,VNB can be converted into ENB by using this catalyst ,the transformation rate and selectivity are about 100% ,take on very higher catalytic activity.
