A method for manufacturing ultrafine particles of hardly water-soluble or water-insoluble organic compounds is disclosed herein, and the method comprises heating and evaporating the organic compound in a vacuum vessel in which an inert gas is introduced in a desired pressure, then condensing and depositing the vaporized organic compound on a recovering means cooled, the resulting ultrafine particles exhibiting a high negative zeta potential sufficient to form a stable water dispersion thereof.
本文公开了一种制造难溶于水或不溶于水的有机化合物超细颗粒的方法,该方法包括在真空容器中加热和蒸发有机化合物,在真空容器中以所需的压力引入惰性气体,然后冷凝并将蒸发的有机化合物沉积在冷却的回收装置上,所得到的超细颗粒显示出高负Zeta电位,足以形成稳定的水分散体。
