Abstract

This article describes a purification method yielding high purity of MFB produced from DMT production process. Aldehyde functional group of MFB included in side-products were converted to acetal compound via reacting with methanol and further separated. Hydrolysis process of the acetal product was continued under acidic condition and highly pure MFB were obtained with 90% yield. The structure of MFB was analyzed by $^1H$ NMR and $^{13}C$ NMR spectroscopy. Also, the purity of MFB was estimated to be over 99% by GC analysis.

본 연구는 Dimethyl terephtalate (DMT) 제조 공정에서 발생하는 반응 부산물로부터 고순도의 Methyl 4-formylbenzoate (MFB)를 정제하는 방법에 관한 내용이다. 반응 부산물에 포함된 MFB의 알데하이드 작용기와 메탄올을 반응시켜 아세탈 화합물로 전환하여 분리하고, 연속적으로 산 촉매 하에 가수분해하여 90% 수율로 MFB를 얻을 수 있었다. 얻어진 MFB는 $^1H$ NMR 및 $^{13}C$ NMR로 구조를 확인하였으며 또한 GC 분석을 통해서 99% 이상의 순도를 확인하였다.
