媒反応にて行なうのが有利である。In the case of reaction in a solvent, an isothiazolone compound such as DCI is dissolved in a commonly used solvent such as ether, methylene chloride, methanol, benzene, ethyl acetate, etc., and a host compound is added thereto for reaction. As a result, the clathrate compound is precipitated as a solid, which is separated by filtration by a conventional method to obtain the desired clathrate compound. Although the clathrate compound of the present invention can be easily obtained by such a reaction in a solvent, in the present invention, it is advantageous to conduct the reaction without a solvent.
即ち、溶媒中反応の場合には、 ■ 溶媒を選定する必要がある。That is, in the case of reaction in a solvent, ■ It is necessary to select a solvent.
■ 条件設定が比較的離しい。■ Condition settings are relatively far apart.
■ □固液分離後の反応濾液の処理が必要となる。■ □It is necessary to treat the reaction filtrate after solid-liquid separation.
■ 特に有機溶媒使用時には人体及び作業環境を保護す

ことができる。In the case of a solvent-free reaction, first, the isothiazolone compound as a guest compound is melted into a liquid. That is, an isothiazolone compound as a guest compound is heated to a temperature higher than its melting point to melt it. For example, DCI
has a melting point of 40℃, so heat it at 60±10℃ on a hot water bath.
Heat to a moderate temperature to melt. Next, the host compound powder is directly added to the guest compound melt and mixed and stirred. In this case, the reaction temperature may be any value within the range of not less than the temperature at which the guest compound is in a molten state and not more than 100°C, and the reaction time may be about 1 to 60 minutes, usually about 5 minutes is sufficient. After the reaction produces an clathrate and solidifies the reaction mixture, the temperature is returned to room temperature to complete the reaction. The formation of clathrate compounds can be confirmed by IR spectroscopy.

ができる。[Function] The clathrate compound of the present invention is usually solid, and since the melting point of the host compound is higher than the melting point of the guest compound, the melting point of the clathrate compound is also higher than the melting point of the guest compound. That is, the isothiazolone compound becomes a solid substance having a higher melting point than the isothiazolone compound by being made into an clathrate compound by a bisphenol compound or a host compound of deoxycholic acid. Therefore, the particles can be pulverized to a desired particle size without being melted by the heat generated during pulverization. The pulverized product thus obtained can be formulated into a formulation using a dispersant or the like as appropriate, and can also be used in an aqueous system as desired. Moreover, since the danger of disinfectants is reduced by inclusion, they can be handled safely.
