蔗糖转化为山梨醇的研究
STUDY ON SUCROSE TURN INTO SORBITOL
【摘要】 将蔗糖分别置于酸和碱介质中对其水解及活化,便进行开环断链,然后在pH=7.5~8.5的NH3·H20—NH4Cl—Na2SO3体系中,在浓度为2mol/L、电解电位为—1.07V、电流密度为3A/dm2、温度为25℃条件下,电解成山梨醇,电流效率为95%以上。
【Abstract】 Sucrose is put into acid and alcali separately while it is hydrolyzed and activated, opening ring and opening link chain,and then in the system of NH3·H2O-NH4Cl-Na2SO3(pH = 7. 5-8. 5, concentration is 2mol/L, electrolytic voltage is -1. 07v, current density is 3A/dm2, temperature is 25℃ ), sucrose is electrolyzed into sorbitol,current efficiency is over 95%.
