| titleOfInvention | Preparation of polyoxyalkylenepolyamine having secondary amino group on its molecular terminal |
| abstract | PURPOSE: To attempt to ease the manufacturing condition of a polyoxyalkylenepolyamine having sec. amino groups on its molecular terminals by reacting a polyoxyalkylenepolyamine having γ-aminopropyl ether groups, which are prim. amino groups, on its molecular terminals with a specified halogen compd. in the presence of a base. n CONSTITUTION: A polyoxyalkylenepolyamine having γ-aminopropyl ether groups, which ar prim. amino groups, on its molecular terminals and an average MW of 400 or larger, such as polyoxypropylenepolyamine is reacted with a halogen compd. of formula RX (wherein R is a 1-20C satd. hydrocarbon group, a 3-20C unsatd. hydrocarbon group, a 6-20C arom, hydrocarbon group or a 7-20C aralkyl; X is F, C1, Br or I), such as isopropyl halide (about 5-200 equivalent % based on the amino groups), in the presence of a base such as an alkali metal hydroxide, a tert. amine 1-10 times by equivalent as much as the halogen compd.). n COPYRIGHT: (C)1990,JPO&Japio |
