Hydrolysis rate
WebThe hydrolysis efficiency of cellulose increased from 40 to 62%, and from 9.6 to 40% after 9.1 days at 15 and 10 °C, respectively, when the pre-hydrolysis at 35 °C was applied. The hydrolysis efficiency of tributyrin at low temperatures with the pre-hydrolysis at 35 °C was similar to those without the pre-hydrolysis. Webprevent the hydrolysis of Na2S and the reaction system is alkaline. NMP will open the ring at high temperature, and finally will affect the quality of PPS. So it is important to study the hydrolysis of NMP in alkaline environment and high temperature. In this work the effects of temperature and alkali on the hydrolysis rate of NMP was studied,
