AZACROWN COMPOUND BEARING HYDROXYLS AND ITS PREPARATION

摘要

NEW MATERIAL:An azacrown compound with hydroxyls of formula I (R1 is H, 1-28C hydrocarbon group, 2-28C hydroxyalkyl; R2O is 2-4C oxyalkylene; n is 1-4). EXAMPLE:9,13-Dihydroxy-1,4,7-trioxa-11-azacyclotetradecane. USE:It is used as an alkali metal capturing agent, metal ion separator, isotope separator, transition metal complex catalyst, and phase transfer catalyst. Further, it is possible to introduce long-chain groups and modify polymeric compounds by utilizing the reactivity of its functional groups and applicable to a variety of uses such as preparation of ion-transferring membranes. PREPARATION:The reaction of oligoalkylene glycol diglycidyl ether with ammonia, substituted amine of 1-28 carbon atoms and hydroxyalkylamine of 2- 28 carbon atoms is conducted in a solvent such as water or methanol to give the compound of formula I .
