| 摘 要： | 2,2,6,6-四甲基-4-哌啶醇有时久置易变色,本文通过GC-MS联用技术分析了变色问题产生的根本原因,是由于未完全还原的哌啶酮氧化所致,并以硼氢化钠为还原剂,通过二次还原的方法处理变色哌啶醇,效果较好。

| Abstract: | It has been known that discoloration occasionally occurs to long-placed 2,2,6,6-tetramethyl-4-hydroxypiperdine;In this paper,GC-MS chromatograms were adopted to analyze the root causes of discoloration which is due to the oxidation of incomplete reduced triacetoneamine.Discolored products were treated by second reduction using as reductive agent and brings better effects. |

| Keywords: | 2 2 6 6-tetramethyl-4-hydroxypiperdine triacetoneamine second reduction discoloration |
