本発明における塩酸クロルプレナリンの晶析造粒法を例
を挙げてさらに詳しく説明すると次の如くである。The crystallization and granulation method of chlorprenaline hydrochloride according to the present invention will be explained in more detail using an example as follows.

d/g、80℃の水の場合には1d/Hの濃度にするこ
とができる。First, chlorprenaline hydrochloride is dissolved in water or ethanol, which is a good solvent. At this time, heating may be performed to increase the solubility of chlorprenaline hydrochloride. The concentration of chlorprenaline hydrochloride in a good solvent depends on the type of good solvent and the temperature.
d/g, and in the case of water at 80° C., the concentration can be 1 d/H.

形造粒物を得ることができる。Next, the above chlorprenaline hydrochloride solution is added to isopropyl acetate, which is a non-solvent, and when the system is stirred, white spherical granules are precipitated. This precipitate is separated by a commonly used method and the solvent is dried to obtain spherical granules of chlorprenaline hydrochloride.

は溶媒非混和系である。Conventional crystallization granulation has been carried out in an immiscible system in which the non-solvent and the good solvent do not mix with each other. One of the remarkable features of the present invention is that spherical granules of chlorprenaline hydrochloride can be obtained even in a system where a non-solvent and a good solvent are mixed with each other. For example, in the present invention, water-cyclohexane and methanol-cyclohexane are solvent-immiscible systems, and ethanol-water-cyclohexane and water-isopropyl acetate systems can be both miscible and immiscible systems. In the case of a water-isopropyl acetate system, if the amount of water is 2.7 d or more per 200 m of isopropyl acetate, it is a solvent-miscible system, and if it is 2.7 d or more, it is a solvent-immiscible system.

るいはテフロンコーティングした容器を用いればよい。The above operations can be carried out using commonly used equipment, ie, equipment made of glass or metal. However, when water, ethanol, or a mixed solvent of water and ethanol is used as a good solvent and cyclohexane is used as a non-solvent, the crystals to be crystallized may adhere to the glass surface and the recovery rate may decrease. In order to avoid the above phenomenon, a Teflon container or a Teflon-coated container may be used.

に分散剤を添加すればよい。Furthermore, when water is used as a good solvent and cyclohexane is used as a non-solvent, the particle size of the crystallized granules may become large. To reduce the particle size, a dispersant may be added to cyclohexane.
この場合の分散剤の種類および量は特に限定されないが
