Abstract

В заявке описан способ селективного регулирования кристаллизации термодинамически стабильной формы 1 или кинетически стабильной полиморфной формы 2 мезотриона из водного раствора мезотриона, где указанный способ включает изменение рН раствора мезотриона до значения, при котором в конечном итоге образуют термодинамически стабильную форму 1 или кинетически стабильную форму 2 мезотриона. Также описан способ преобразования формы 2 мезотриона в форму 1 мезотриона. Кроме того, изобретение касается и применения регулирования рН до значения ≤ 2,5 для получения термодинамически стабильной формы 1 мезотриона.
