Utilizing sugar compounds as feedstock for conversion to HMF is sustainable and economically viable. A heterogeneous base catalyst, SBA-15-SO3H, has been created for fructose hydrolysis reactions, showing excellent catalytic performance. The catalyst allows for high fructose conversion rate and HMF yield under mild conditions, fast reaction rate, and simple operation.
Utilizing sugar compounds (such as fructose) as feedstock for conversion to HMF is very appealing, because it makes the production processes sustainable and improves the economic viability of platform molecules derived from biomass. Here, SBA-15 with sulfonic acid functionalization was created as a heterogeneous base catalyst for fructose hydrolysis reactions to create significant platform chemicals. A fructose conversion rate as high as 100%, along with a 78.7% yield of HMF, were obtained in DMSO at 130 degrees C after 1 h. The excellent catalytic performance of SBA-15-SO3H in fructose hydrolysis reactions was confirmed by the activation energy's low value (56.99 kJ/mol). The mild conditions, fast rate of reaction, and simple operation are worth mentioning for other catalysts. SBA-15-SO3H has the potential to promote fructose conversion at lower temperatures.
