応物を加熱する。 During a normal reaction, the heat transfer liquid is not circulated and 3
The heating medium liquid is heated by heaters 41 and 42 to generate steam, and the heating medium vapor is sent to the heating jacket 2 to heat the reactant.

物）を冷却する。 If the temperature of the reactants rises too much during the reaction or if it is necessary to cool the reactants to keep the temperature of the reactants low after the reaction is complete, turn off the heaters 41 and 42 and The medium liquid is extracted by a pump 6 and cooled by a cooler 7, and the cooled heat medium liquid is showered from showering nozzles 81 and 82 into a heating jacket at the top of the reactor and flows down along the outer wall of the reactor. Cool the reactor (reactant).

よらなければならず、極めて冷却効率が悪かつ
た。 In a conventional reactor without a heat medium liquid circulation device, when cooling the reactants, the heaters 41 and 42 must be turned off and indirect heat transfer due to heat radiation from the outer wall of the jacket must be used, resulting in extremely poor cooling efficiency. .
これに対して、本考案の装置によれば、反応物

に冷却することが可能となる。 On the other hand, according to the device of the present invention, when the reactants are cooled, the cooled heat transfer liquid flows down along the outer wall of the reactor, so the reactor is directly cooled and the effective heat transfer area is reduced. This makes it possible to quickly cool down the reactants.
