Abstract

This study was conducted to investigate the pyrolysis products of ι-menthol by Curie-Point pyrolysis. The pyrolysis of ι-menthol was performed at 16$0^{\circ}C$, 42$0^{\circ}C$, $650^{\circ}C$, and 92$0^{\circ}C$ by Curie-Point Pyrolyzer and their pyrolysis products were analyzed by GC/MSD. In addition, tobacco leaves added ι-menthol were pyrolyzed at the same condition in case of ι-menthol. The beginning temperature for pyrolysis formation was in the vicinity of 42$0^{\circ}C$ and the major components of the pyrolysis products identified were iso-menthol, 2-menthene, menthomenthene, and menthone. The amount of these components was increased by increasing temperature and the hydrocarbons such as hexadecene and pentadecene formed by ring cleavage were generated at 92$0^{\circ}C$. The yield of ι-menthol in pyrolysis of tobacco leaves was decreased as the temperature of pyrolysis was raised and the pyrolysis products of ι-menthol weren't identified in the pyrolysis of tobacco leaves. Also, to analyze the weight decrease, ι-menthol was analysed by thermal analyzer(TA), and then the weight decrease of ι-menthol was occurred in the vicinity of 18$0^{\circ}C$.
