| Abstract: | D-Glucono delta-lactone was produced from D-Gluconic acid using molecular sieve MCM-41 as catalyst.Effects of various factors on D-Glucono delta-lactone yield,including reaction temperature,reaction time,catalyst dosage and recycling index of molecular sieve MCM-41,were discussed.Experimental results showed that molecular sieve MCM-41 was a better catalyst for preparation of D-Glucono delta-lactone.The optimum reaction condition was obtained as follow:catalyst dosage 30%,reaction temperature 80℃,and reaction time 2 h,under which D-Glucono delta-lactone yield was as high as 90.39%. |
