摘要:
This invention relates to a method for synthesizing 1 -amino piperidine (N- aminopiperidine) which selects a proper molar ratio of the starting materials, preferably a cumulative mole ratio of piperidine to the aqueous hydroxylamine-O-sulfonic of at least 2: 1, and closely regulates the reaction temperature and the method of product isolation to achieve a high product conversion.
