Analysis of 4-hydroxy-3-methoxybenzaldehyde pyrolyzates by Curie-point pyrolyzer-GC/MSD

유의경, 김옥찬

초록

바니린을 Curie-point pyrolyzer-GC/MSD 장치를 사용하여 920, 740, 500, 333℃에서 각각 열분해하고, 열분해 생성물을 분리 및 확인하였다. 확인된 성분중에서 920℃에서는 95개 성분, 740℃에서는 40개 성분, 500℃에서는 17개 성분, 333℃에서는 11개 성분을 확인할 수 있었으며 이 열분해 반응생성물 중 주요 생성물인 벤젠, 페놀, 2-히드록시 벤즈알데히드, 2-메톡시페놀, 4-메톡시벤즈알데히드, 벤즈알데히드, 메톡시벤젠, 1,3-시크로펜타디엔 등은 바니린의 작용기가 해리되었거나, 분해된 생성물로 생각되며, 1,3-benzodioxole-5-carbox-aldehyde, 메틸벤젠, 스틸렌, 메틸페놀 등은 500℃ 이하에서도 바니린의 메톡시 작용기가 해리되어 생성되는 것으로 생각된다.

This study was carried out to present a analysis of pyrolytic degradation of 4-hydroxy-3-methoxybenzal dehyde(vanillin) pyrolyzed at 330℃∼920℃ by Curie-point pyrolyzer connected with GC/MSD by on-line system. Identified by GC/MSD were 100 pyrolytic products of vanillin. The pyrolysis of the compound gave benzene, phenol, 1,3-cyclopentadiene, methyl benzene, benzaldehyde, benzofuran, and cresol as major products, which were produced by pyrolytic degradation and synthesis of vanillin radicals.
