Oxidation of a mixture of glucose and arabinose over 1% Au deposited on alumina was investigated in a semi-batch reactor varying pH, temperature and partial pressure of oxygen. Elevation of the latter enhancing the rate induced also losses in selectivity to aldonic acids. A kinetic model representing the catalytic oxidation reactions of arabinose and glucose along with respective isomerization to fructose and ribulose was developed. Calculations based on the model were able to describe experimental data in a reliable way.

葡萄糖和阿拉伯糖混合物在Au / Al 2 O 3上的氧化

在改变pH，氧气温度和氧气分压的半间歇式反应器中研究了葡萄糖和阿拉伯糖混合物在1％以上沉积在氧化铝上的氧化。后者的升高提高了速率，也引起了对醛糖酸选择性的损失。建立了代表阿拉伯糖和葡萄糖催化氧化反应以及分别异构化为果糖和核糖的动力学模型。基于模型的计算能够可靠地描述实验数据。
