Abstract:

This paper deals with the relationships between the dissolution rates of pentaose and hexose and such parameters as temperature,time as well as the initial mass concentration of dilute acid during the dilute acid-aided prehydrolysis of Eulaliopsis binata.The results show that high temperature is helpful to the dissolution of carbohydrates,and that,at the same temperature,the dissolution rates of pentaose and hexose,which have functional relation with the prehydrolysis factor,both increase with the hydrolysis time and the initial mass concentration of dilute acid.Moreover,fitting results indicate that there also exist functional relationships between the dissolution rates and the initial mass concentration of dilute acid.Based on the experimental results,two empirical models respectively describing the dissolution laws of pentaose and hexose are established,with their correctness and effectiveness being verified at last.

Key words: Eulaliopsis binata, dilute acid-aided prehydrolysis, dissolution law, pentaose, hexose
