Abstract

The pyrolysis conditions for the thermal isomerization products of pinane were carried out by the furnace type pyrolyzer and the curie-point pyrolyzer equipped with gas chromatograph and mass spectrometer. It was confirmed that curie-point type is much better furnace type, and high yield (70%) of citronellene was obtained from pinane as the main isomerization product under the best conditions by curie-point type. The optimum conditions of pyrolysis are $590^{\circ}C$ for 4 sec. and the major products were indentified as citronellene, m-Menth-6-ene, m-Menth-1-ene and 1-Methyl-4-(1-methylethylidiene) cyclohexane.

피난의 열 이성화반응 생성물에 관한 연구를 위하여 열분해 조건을 가스크로마토그래피와 질량분석기에 장치된 전기로형 및 curie-point 열분해기를 이용하여 실험을 행하였다. 그 결과, 최적 조건하에서 전기로형보다는 curie-point 열분해기에 의해서 피난으로부터 주 이성화 생성물인 citronellen (70%)을 얻었다. 본 연구에서 열분해 최적 조건은 $590^{\circ}C$, 4 Sec이고, 확인된 열분해 주 생성물은 citronellene, m-Menth-6-ene, m-Menth-1-ene, 1-Methyl-4(1-methyl-ethylidene) cyclohexane이었다.
