At present, the domestic research on the theoretical aspects of ultrasound is still relatively weak, and the specific mechanism of interaction between cavitation and matter is not comprehensive enough; the targeting of ultrasound equipment needs to be further strengthened; the cavitation and thermal effects of ultrasound are promoted At the same time, the reaction also produces a series of abnormal side reactions. How to reduce the occurrence of side reactions is one of the difficulties in research; although ultrasound has achieved important results in the field of petrochemicals, the realization of industrial production still lacks a certain theoretical basis and amplified experimental research Therefore, in-depth study of the operation process of ultrasonic experiments, optimization of experimental parameters, and development of scale-up experiments are currently difficult problems to be solved and one of the focuses of future research.
