Description

    The present invention relates to an organic synthesizer that synthesizes a reagent contained in a reaction vessel by stirring, heating, and adjusting pressure in the reaction vessel.

    Conventionally, an organic synthesizer has been used to synthesize many kinds of reagents at the same time or under different conditions at once, and to test the synthesized reagents all at once. As this organic synthesizer, in addition to an atmospheric pressure type organic synthesizer that synthesizes a reagent contained in the reaction vessel by stirring and heating the reagent in the reaction vessel at normal pressure (see Patent Document 1), There is a pressure adjustment type organic synthesizer capable of adjusting the pressure in a reaction vessel such as pressurization and decompression in addition to stirring and heating of a reagent.

  However, in an organic synthesizer, when a pressure-controlled reaction and a general reaction at normal pressure are performed at the same time, even if not all of the supportable reaction vessels are used, the pressure adjustment type and the normal pressure type It is necessary to prepare and use each organic synthesizer separately, but when using a pressure adjustment type and a normal pressure type separately as described above, it is more space-consuming than using only one of them. In addition, there may be an error in reaction conditions other than reaction pressure such as stirring conditions and heating conditions between the two.

  Further, in the above-described pressure adjustment type organic synthesizer, when the reaction vessel is removed from the organic synthesizer, as shown in FIGS.

    By performing the above operation with the second pressure adjusting unit 14B removed, the pressure can be adjusted only in the reaction vessel whose pressure is adjusted by the first pressure adjusting unit 14A. That is, as shown in FIGS. 5 and 6, the second pressure adjustment unit 14B is removed, and the reaction vessel in which the second pressure adjustment unit 14B is removed performs a normal pressure reaction, and the pressure is only applied by the first pressure adjustment unit 14A. Adjustments can be made. When the second pressure adjustment unit 14B is removed and a normal pressure reaction is performed, a normal pressure vessel 64 is used instead of the pressure resistant vessel 16. In this case, a reflux block 66 that is provided above the atmospheric pressure vessel 64 and below the top plate 22 and cools the vaporized material in the atmospheric pressure vessel 64 to return it to a liquid, and a reagent in the reaction vessel.

As shown in FIG. 1, the openings 60a to 60d are first openings 60a _{1 to} 60d ₁ extending in the vertical direction, and second openings 60a ₂ extending leftward from the upper ends of the first openings 60a _{1 to} 60d _1. to 60d _2, and inverted L-shape is formed by a third opening 60a ₃ to 60d ₃ slightly extending downward from the second left openings 60a ₂ to 60d _2. The third openings 60a _{3 to} 60d ₃ are formed at positions that do not overlap with the vertical direction of the pressure-resistant vessel 16 in which the reaction vessel is accommodated. The leading ends of the seventh and eighth pipes 40g, 40h, 40′g and 40′h extend beyond the first and second housings 30A and 30B from the openings 60a to 60d. The first and second casings 30A and 30B are connected to the first to fourth gas supply / discharge pipes 19a to 19d on the outside. That is, as shown in FIGS. 1 and 2, the seventh and eighth pipes 40g, 40h, 40′g and 40′h extend from below to above the openings 60a to 60d, respectively, and reach the highest position. from the highest position downwards to form a helical portion 62a to 62d, and reaches the position below the second opening 60a ₂ to 60d ₂ of the opening 60a to 60d, extending outwardly from the openings 60a to 60d, Further, it is bent vertically downward and connected to the first to fourth gas supply / discharge pipes 19a to 19d.

Since the positions of the lower ends of the third openings 60a _{3 to} 60d ₃ where the gas supply / discharge pipes 19a to 19d are allowed to stand still do not overlap with the vertical direction of the pressure resistant container 16 in which the reaction vessel is accommodated, The container 16 can be attached and detached. At this time, since the seventh and eighth pipes 40g, 40h, 40'g and 40'h form the spiral portions 62a to 62d, the first to fourth gas supply / discharge pipes 19a to 19d are connected to the pressure-resistant container. The stress which is distorted in the vertical and horizontal directions generated when being removed from the pipe 16 is absorbed by the spiral portions 62a to 62d of the seventh and eighth pipes 40g, 40h, 40'g and 40'h. Therefore, when the user attaches / detaches the reaction vessel to / from the organic synthesis apparatus, first, the user has the first to fourth gas supply / discharge pipes 19a to 19d and easily moves along the shapes of the openings 60a to 60d. It is possible. In addition, the movement does not impose a load on the first to fourth gas supply / discharge pipes 19a to 19d and the parts fixing them.
