As the biodiesel production is increasing rapidly, the crude glycerol, which is principal by-product of biodiesel production, has also been generated in a large amount. Many research studies on value-added utilization of glycerol are under investigation. 1,3-Propandiol is a promising chemical which ...

바이오디젤 생산공정의 주요 부산물은? | 바이오디젤 생산공정에 있어 주요 부산물은 글리세린인데 원료가 되는 오일의 10%가 바이오디젤이 아닌 글리세린으로 전환된다[1]. 글리세린(1,2,3-propanetriol or glycerine)은 그 동안 합성 계면활성제의 개발에 따라 프로필렌이나 에피클로로하이드린(epichlorohydrin)으로부터 생산되어 왔다. | |
트리메틸렌 글라이콜이 최근 주목 받게 된 이유는? | 1,3-PDO는 트리메틸렌 글라이콜(trimethylene glycol) 혹은 1,3-디하이드록시프로판(1,3-dihydroxypropane) 등으로도 불리는 비교적 간단한 구조의 유기화학물질이며 UV-큐어링 코팅, 지방족 폴리에스터, 용제, 부동액을 비롯한 다양한 용도를 가진다. 1,3-PDO가 최근 주목 받게 된 것은 기존 화학합성에 의해 생산되던 PTT (Poly(trimethylene terephthalate))가 생물학적으로 생산된 1,3-PDO로부터 생산되었기 때문이다. 전 세계적으로 1,3-PDO에 대한 수요는 대략 20만톤으로 추정되고 있으나 향후 PTT의 수요 증가에 따라 시장 규모가 급격히 늘어날 것으로 전망하고 있다. | |
글리세린을 이용한 고부가가치 제품으로는 무엇이 있는가? | Fig. 1에서 보듯이 글리세린을 이용한 고부가가치 제품으로서는 1,3-프로판디올(1,3-propnaediol, 1,3-PDO), 1,2-프로판디올(1,2-propanediol), 디하이드록시아세톤(dihydroxyacetone), 수소, 폴리글리세롤(polyglycerol), 숙신산(succinic acid), 폴리에스터 등이 있지만[2,3], 본 총설에서는 클루드 글리세린의 유망한 활용 방안 중 하나로서 1,3-PDO의 생물학적 생산으로의 응용과 이에 따른 분리기술 현황과 전망을 다루고자 한다. |
