【Abstract】 This paper discussed the effects of treatment temperature,treatment time and HCl concentration on producing the microcrystalline cellulose by high temperature and pressure process.The results showed that from the microcrystalline cellulose obtained rate,the conditions in product microcrystalline cellulose by high temperature and pressure process were optimal as a collection which included HCl with 2.5% of concentration,180 min of treated time and 130℃ of hydrolytic temperature.However,in the comparison system of surface expansion volume,the collection by high temperature and pressure process was better,with HCl with 1.0% of concentration,120 min of treated time and 150℃ of hydrolytic temperature.更多还原
