Method and device for adjustment of the temperature chemical reactions.

The temperature adjustment device includes a thermally insulated reactor, a dosing device introducing the materials participating in the reaction, a cooling system and sensor means of the reaction temperature as well as an adjustment unit. member for feeding the coolant medium in the cooling system is a liquefied gas evaporation means consisting of a coil 35 or a cooler 40 or a dispersing element 41, 42. Application to direct setting a reaction temperature by vaporizing liquefied gas.
