Preparation of pentose with high yield from bamboo sweeps catalyzed by maleic acid
The hydrolysis conditions of bamboo sweeps hemicelluloses catalyzed by maleic acid are optimized using single factors and orthogonal experiments.The results show that the liquid-solid ratio has the most significant effect on the hydrolysis process of bamboo sweeps hemicellulose.With the increase of maleic acid concentration,the pentose yield can be increased up to 99.88 ％.Under 0.3 mol/L of maleic acid concentration,the optimum hydrolysis conditions are as follows:140℃ of hydrolysis temperature,8 hours of the hydrolysis time and 50 of liquid-solid ratio.Under the optimal condition,the pentose yield is 98.15 ％ and weight lose rate is 22.17 ％.
