Abstract:The production of xylose via hydrolysis of straw in a mixture of formic acid and hydrochloric acid was investigated. Results showed that the yield of straw xylose reached 23.62% with saturated formic acid containing 10% HCl, reaction time of 0.5 h and temperature of 65 ℃. The hydrolysate was purified with D311 and activated carbon for decoloration and then crystallized, giving the pure xylose with the yield of 15.87%. Results indicated that this technology was available.
