기존에 금속 촉매를 이용한 화학반응은 수율이나 반응조건등 여러 단점들이 많이 있습니다.
이를 대체하기 위한 효소반응에 관련된 연구가 많이 진행되고 있습니다.
기존 화학공정의 단점과 효소반응의 장점에 대해서 기술했습니다.
Enzymes for catalytic polymerization
Direct Synthesis of Polymers
The use of enzymes or whole cells as catalysts in specialty chemical synthesis during the last ten years has become a useful technique.
New trends in polymer synthesis are derived from researches involving in vitro specialty chemical synthesis using biocatalyst.
can be prepared through an exchange reaction between ester and hydroxyl groups, usually called alcoholysis.
proceeds very slowly in the absence of catalysts, even at high temperatures. Of the many catalysts, the most effective are acetates of Pb(II), Pb(IV), Zn, Mg, Ca, Co, and Cd, oxides such as Sb2O3 and GeO2.
