Effect of Particle Size of DABCO- and DBU- Intercalatedα-Zirconium Phosphate as Latent Thermal Catalysts inthe Reaction of Glycidyl Phenyl Ether（GPE） andHexahydro-4-Methylphthalic Anhydride（MHHPA）

Abstract

In the presence of DABCO- and DBU- intercalated with various size of α-zirconium phosphate（ ZrP）,the reaction of glycidyl phenyl ether（ GPE） and hexahydro-4-methylphthalic anhydride（ MHHPA） wascarried out. As the results, these intercalates displayed catalytic activities under thermal conditions and theintercalation compound with smaller ZrP（ 0.73 μm） was more active than bigger ZrP（ 1.92 μm）. The thermalstabilities of GPE - MHHPA with those catalysts at 40 ℃ for 13 days were confirmed: the conversions of GPEwith ZrP·DBU were less than 10 ％ up to 2 days. The reaction with ZrP·DABCO, the conversions of GPE wereless than 10 ％ up to 4 days. These intercalates showed thermal latency in the reaction of GPE - MHHPA.
