摘要

我们表明，低频可听到的声音能够驱动结晶的不同固体形式的有机化合物在溶液结晶。使用自制的仪器，进行悬浮或机械耦合结晶。ROY在乙醇、异丙醇和水中的氨基苯甲酸中结晶，凝固出单一的多晶型、伴随形式和根据频率（Hz）和振幅（dB）的声音参数优选的取向，证明了声音控制结晶。意想不到的结果包括ROY Y型的纤维状形态，这是由于明显的（010）偏好取向，以及从不太可能的水溶液中获得的邻氨基苯甲酸形式I。

Controlling crystallisation with audible low frequency sound

We show that low-frequency audible sound is able to drive the crystallisation of distinct solid forms of organic compounds in solution crystallisation. Using a home-made apparatus, suspended or mechanically coupled crystallisations were performed. Crystallisations with the compounds, ROY in ethanol and isopropanol and anthranilic acid in water, solidified out single polymorphs, concomitant forms, and preferred orientation depending on the sound parameters of frequency (Hz) and amplitude (dB), evidencing a sound controlled- crystallisation. Unexpected outcomes include the fiber-like morphology of the ROY Y form due to pronounced (010) preferred orientation, and the anthranilic acid form I obtained from unlikely aqueous solvent.
