Based on the microwave method with using sucroses as raw materials and concentrated hydrochloric acid as catalyst and acidifier,a product of levulinic acid and formic acid by-products are generated by the intermediate product 5 - hydroxymethyl-furfural and decarboxylation. The experimental results have shown under the condition that the concentration of hydrochloric acid being 4mol/L, the concentration of sucrose being 50g/L and 70% of the microwave power being used with a five-minute reaction time, the most maximum acid production can be reached at the rate of 52.4%. It is obviously improved compared with the rate 22.4% on the literature value.
呵呵,应该通顺了。。
