以天然丝光沸石为催化剂的莰烯酯化法是合成樟脑生产中较理想的方法之一。本文利用气相色谱-质谱联用和毛细管气相色谱系统地研究了该新工艺中原料莰烯和酯化产物的各种杂质,并讨论了各种杂质的形成机理,以及反应条件对杂质含量的影响。
Carnitine esterification method using natural mordenite as catalyst is one of the ideal methods for synthesizing camphor. In this paper, gas chromatography-mass spectrometry (GC-MS) and capillary gas chromatography (GC-MS) were used to systematically study the various impurities of the acenaphthene and esterification products in the new process. The formation mechanism of various impurities and the influence of reaction conditions on the impurity content .
