摘要:Disclosed in the present invention is a method for an acoustic resonance enhanced chemical reaction, comprising: step 1, adding reaction material components into a reactor, the reactor being fixed on an acoustic resonance reaction platform; step 2, by means of the phase difference, adjusting the acceleration G of the acoustic resonance reaction platform, and performing frequency sweep in the low frequency range to determine that the frequency corresponding to peak value acceleration G is the resonance frequency; step 3, reacting the reaction material components under the conditions of the resonance frequency and a set acceleration G1, and sequentially filtering, and drying, and heat drying the suspension obtained from the reaction, so as to obtain a reaction product; wherein the acceleration G and the acceleration G1 are all fixed values, the value range is 1g ≤ G ≤ 90g, 1g ≤ G1 ≤ 90g, G is the gravity acceleration, and the value is 9.8 m/s 2 . The method in the present invention is suitable for various reaction systems including gas-liquid, liquid-liquid, solid-liquid and heat-release systems, has mild reaction conditions, and is particularly suitable for the synthesis of dangerous chemicals with high sensitivity to mechanical stimulation.
