To overcome the shortcomings of low acid loading and uneven distribution in the existing preparation methods of micron-sized silicon-based sulfonic solid acids, a method was proposed to prepare micron-sized silicon-based sulfonic solid acids using ultrasonic enhanced technology. The effect of different reaction parameters, such as time, power, and temperature of ultrasonication, sulfonation temperature and time, and sulfuric acid concentration, on acid loading in solid acid was investigated in this work. The results showed that a micron-sized mesoporUltrasonics sonochemistry106689https://www.ebi.ac.uk/biostudies/studies/S-EPMC10692911biostudies-literatureEffect and mechanism of ultrasound on acid loading in the preparation of silicon-based sulfonic solid acids.PMC10692911Hu JHuang WWang TLe TMiao WZhang LRavindra AVXv HfalseEffect and mechanism of ultrasound on acid loading in the preparation of silicon-based sulfonic solid acids.Silicon-based sulfonic solid acids have the advantages of high catalytic activity and selectivity, easy separation from products, low equipment corrosion, and environmental protection, and sulfuric acid loading is the key to their preparation.
