| Abstract: | Using Pd-Bx/C as catalyst,potassium gluconate was prepared through the catalytic oxidation of glucose.The influencing factors on the conversion of glucose,such as catalyst,mass fraction of glucose,input rate of O2,speed of stir,were investigated.The optimal conditions were obtained,which were as follows:the mass fraction of glucose was 35%,the input rate of O2 was 80 L/h,and the mass ratio of Pd-Bx/C to glucose was 2%.The experiments were carried out under the above optimal conditions,the average yield of potassium gluconate was 97.87%,and the conversion of gluconate was 98%~99%. |
