研究了麦草在甲酸-乙酸-水复合有机酸( FAWOA)体系中于常压反应条件下，反应温度和时间对麦草各组分溶出规律的影响。结果表明：麦草在与复合有机酸反应过程中，脱木质素历程可以分为3个阶段：大量脱木质素阶段，补充脱木质素阶段和残余脱木质素阶段，各阶段木质素溶出分别为37.1%、27.2%和2.50%；戊聚糖的反应历程也分为3个阶段：戊聚糖大量反应阶段、补充反应阶段和少量反应阶段，各阶段戊聚糖溶出分别为50.0%、24.9%和3.20%；综纤维素、苯-乙醇抽出物和灰分的溶出呈现与脱木质素、戊聚糖溶出相似的趋势；黑液中有机物含量的增加趋势与木质素和戊聚糖溶出趋势相似，而无机物含量变化很小，基本维持在2.0 g/L左右。

Biorefinery process by organic acids is a potential way to utilize wheat straw effectively. The influences of reaction temperature and time on the dissolutions of the wheat straw chemical components in formic acid-acetic acid-water organic acids ( FAWOA) at atmospheric pressure were investigated in present study. The results indicated that the delignification process can be divided into three phases, namely a bulk phase, a complementary one and a residual one, with lignin removal by 37. 1%, 27.2% and 2. 50% respectively. The dissolution of pentosan also demonstrated as three stages, i. e. , a bulk one, a complementary one and a residual one, with the dissolution ratios of 50. 0%, 24. 9% and 3. 20% respectively. The removal of holocellulose, benzene-ethanol and ash can be divided into similar three phases as the removal of lignin and pentosan. The increasing trend of organic matter content in black liquor was similar to that of lignin and pentosan. However, only a slight variation of inorganic matter content was observed and represented a constant level at 2. 0 g/L in the biorefinery process.
