を防止する必要がある。(Prior Art) In chemical synthesis reactions, it is common to use instruments made of glass, plastic, or metal and operate under reduced pressure. In such cases, foreign matter such as oxygen in the air, dirt, or grease used in the rubbing parts may be introduced into the reaction system from the rubbing parts of the joints attached to each device or the rubbing parts that connect each equipment. It's easy to get lost. When synthesizing compounds that require extremely high purity, such as raw materials for electronic materials, it is necessary to prevent foreign substances from entering the reaction system.

A communication hole 3 for passing fluid through is formed in the center of the pot 1. There is no particular restriction on the diameter of the flow hole 3, but it is usually 1 to 5 mm. Grooves 4 and 5 are provided on the outer peripheral surface of the pot 1 on both sides of the communication hole 3 over the entire circumference. Groove 4
There is no particular restriction on the width and depth of 5 and 5, but the width is usually 0.5 to 5 mm and the depth is 0.1 to 1 mm. Two or more grooves may be provided on each side of the communication hole 3. Each groove 4 and 5 is provided with at least one hole 6 and 7 communicating with the hollow part 8 . The diameter of holes 6 and 7 is the same as that of groove 4.
and 5 is preferably approximately equal to the width. A plurality of holes may be provided in the grooves 4 and 5.

止することができる。 An inert gas such as nitrogen gas or argon gas is introduced through one opening of the pot 1 under a slight pressure, for example under a pressure of 2 kg/cm 2 or less, and is discharged through the other opening. The introduced inert gas is sent to the grooves 4 and 5 from the holes 7 and 8 via the hollow part 8. Therefore, foreign matter such as air that enters from the rubbing portion of the pot 1 and the female mold 9 cannot enter inside the grooves 4 and 5. Therefore,
It is possible to effectively prevent foreign matter from being mixed into the fluid flowing through the fluid passage 10 of the female mold 9 and the flow hole 3 of the pot 1.
