Abstract

By using in situ Raman spectroscopy for reaction monitoring, we compare ball milling (BM) and resonant acoustic mixing (RAM) in the preparation α,β-unsaturated ketones (chalcones). RAM achieves similar transformations to BM, though adjustments in reaction conditions may be necessary due to different mixing regimes.

比较有机机械合成中球磨和共振声混合的原位拉曼光谱
利用原位拉曼光谱技术对α,β-不饱和酮(查尔酮)的制备过程进行了对比,比较了球磨法(BM)和共振声混合法(RAM)制备α,β-不饱和酮(查尔酮)的效果。RAM实现了与BM类似的转化,尽管由于不同的混合制度,可能需要调整反应条件。
