この発明は・、生理用品なとの吸臭剤に用いられる脱臭
剤を製造する方法に関する。DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application] This invention relates to a method for producing a deodorizing agent used in sanitary products and other deodorants.
このような脱臭剤としてはヤンガラ活性炭に代表される
活性炭かある。Activated carbon such as Yangara activated carbon is an example of such a deodorizing agent.

着剤として用いることも知られている（特開昭６０−１
３７８１．２号公報等参照）。It is also known that calcined montmorillonite mineral can be used as an adsorbent for deodorizing agents (Japanese Patent Laid-Open No. 60-1
(See Publication No. 3781.2, etc.).

られたものを脱臭剤とすることにより、上記課題を解決
するようにした。In this invention, the above-mentioned problem is solved by hydrating and swelling the montmorillonite mineral, then rapidly freezing it, and then freezing and vacuum-drying the resulting product as a deodorizing agent.
上述の製造方法によって得られた脱臭剤は塩基性臭気化
合物および酸性臭気化合物の両者に対して良好な吸着性
を発揮する。The deodorizing agent obtained by the above production method exhibits good adsorption properties for both basic and acidic odor compounds.
以下、この発明の詳細な説明する。The present invention will be described in detail below.
この発明で用いられるモンモリロナイト鉱物とは、化学
名水和珪酸マグネシウムて表わされる鉱物であって、イ
オン吸着性、著しい膨潤性を有する鉱物である。The montmorillonite mineral used in this invention is a mineral represented by the chemical name hydrated magnesium silicate, and is a mineral that has ion adsorption properties and remarkable swelling properties.
まず、このモンモリロナイト鉱物を水中に分散させて、
水和膨潤させる。水中での分散濃度は３〜５重量％程度
とされる。用水には、水道水などの上水が好ましい。具

とし、撹拌装置には剪断力が充分に加わる高剪断型のも
のが望ましい。温度は常温で十分である。First, this montmorillonite mineral is dispersed in water,
Hydrate and swell. The dispersion concentration in water is approximately 3 to 5% by weight. The water for use is preferably tap water or other tap water. Specifically, a tank equipped with a stirring device is filled with clean water,
While stirring the jt, a predetermined amount of powdered montmorillonite mineral is gradually added little by little and stirred thoroughly. If the montmorillonite mineral is immersed all at once, it is inconvenient that insoluble lumps will form. The stirring time is about 120 to 300 minutes, and the stirring device is preferably a high-shear type that can apply sufficient shear force. Room temperature is sufficient.
このような撹拌によりモンモリロナイト鉱物は均一に分
散するとともに水和膨潤して、均一すｉ＆状となる。By such stirring, the montmorillonite mineral is uniformly dispersed and swelled by hydration, so that it becomes uniformly shaped.

速凍結を行ってもよい。Next, this hydrated swollen product is quickly frozen. Rapid freezing is performed by directly or indirectly contacting the hydrated swollen product with a low-temperature medium.
It freezes in a short time of about 10 seconds, such as -60 to -50°C of an ethanol/dry ice mixture.
It is possible to use a cooling medium of about In other words, when an insulated container such as a Dua bottle is filled with ethanol and chunks of dry ice are poured into it, the temperature of the ethanol decreases, and eventually becomes a slightly viscous liquid, and the temperature increases as the dry ice is added. The temperature drops to about -50 to -60'C depending on the amount. When the hydrated swollen product is dropped into the ethanol/dry ice mixture in this state, the hydrated swollen product freezes instantaneously, floats up and collects on the ethanol liquid surface, and a frozen product is obtained. Of course, other cooling media can be used, such as liquid nitrogen. Alternatively, the hydrated swollen product may be sprayed in the form of a mist into a cryogenic gas such as cryogenic air or cryogenic nitrogen at a temperature of about -150 to -100°C to perform rapid freezing.
このようにして得ら、れた凍結物はＯ′Ｃ以下の雰囲気

□間の範囲で適宜選択される。The frozen product thus obtained is placed in a freeze-vacuum drying apparatus while maintaining the frozen state in an atmosphere below O'C, and is freeze-vacuum-dried. As the freeze-vacuum dryer, a well-known batch type or continuous type equipped with a drying chamber, cold wrap, vacuum evacuation device, etc. is used, and its operating conditions include a pressure of lx 10-' to lx 10-'. mm
1li7, the temperature is appropriately selected within the range of 1 to 24 hours.
このような凍結真空乾燥によって、凍結物中の水分が昇
華、除去され、乾燥した微細多孔質の粉末状物質が得ら
れ、このものが脱臭剤となる。By such freeze-vacuum drying, water in the frozen material is sublimated and removed, and a dried fine porous powder material is obtained, which becomes a deodorizing agent.
このようにして得られた脱臭剤は後述する実施例からも

を発揮する。The deodorizer thus obtained exhibits a high odor absorption rate for both acidic and basic odor compounds, as is clear from the Examples described below. Conventional deodorizers have the characteristic that those that absorb acidic odor compounds cannot absorb basic odor compounds, and conversely, those that absorb basic odor compounds do not absorb acidic odor compounds. The deodorizing agent obtained above specifically exhibits good odor absorbing properties against both acidic and basic odor compounds.
