Production of Furfural from Rice Straw by Microbial Treatment(II)-Production of Furfural from Xylose by Acid Treatment-
본 연구는 미생물을 이용한 볏짚으로부터 Furfural 제조에 관한 제2단계 연구로서, 제1보（화학공학 Vol. 21, No. 5, Oct., 1983）의 연구결과로 얻어진 Xylose를 산처리하여 Furfural을 제조하는데 있어서의 제반조작 조건과 반응기구에 대하여 연구하였다.
Xylose로부터 Furfural로의 전환에 있어서 회분, 등온 반응조건에서 Furfural 수율은 초기 Xylose농도, 황산의 농도, 반응온도 및 반응시간의 함수임을 확인하였으며 초기 Xylose농도가 낮을 때 Root의 반응속도식과 잘 일치하였다.
본 실험에서 0.2 N 황산을 사용하여 초기 Xylose농도가 0.0067 gmol/L이고 반응온도가 200 ℃, 반응시간 10분일 때 최대 수율 72 %를 얻을 수 있었다.

This study is the second step on the production of furfural from rice straw by microbial treatment, based on the first research（HWAHAK KONGHAK, Vol. 21, No. 5, Oct., 1983）.
The reaction condition and mechanism of furfural production from xylose by acid treatment have been studied. The xylose was obtained from rice straw by the first step research. Furfural yield at batch-isothermal condition was a function of initial xylose concentration, sulfuric acid concentration, reaction temperature, and reaction time. And when the initial xylose concentration was low, the results were consistent with those of Root's reaction mechanism.
Maximum furfural yield was obtained under conditions of sulfuric acid concentration, 0.2 N, initial xylose concentration 0.0067 gmol/L, reaction temperature 200 ℃, and reaction time 10 minutes.
