A STUDY ON ISOMERIZATION OF VINYL NORBORNENE(Ⅱ) ──(Na_2O-Na)/(γ-Al_2O_3 )TYPE SUPERBASE CATALYST

介绍了用于乙烯基降冰片烯异构化的（Na2O－Na）／（γ－Al2O3）超强碱催化剂研究成果。该催化剂最高碱强度H_达到43以上。其碱强度高于35的碱的量达到5．5～6．0mmol／g催化剂,呈现出良好的乙烯基降冰片烯异构化活性。

In the article, a new Na2 O-Na/γ-Al2O3type superbase catalyst which is usable for isomerization of vinyl norbornene is reported. Highest base strength (H_ ) of the superbase catalyst reaches over 43, basicity of base which strength is higher than 35 is 5. 5 ~ 6. 0 mmol/g catalyst. The superbase catalyst exhibits excellent catalytic activity for isomerization of vinyl norbornene.
