Novel reaction kettle

The utility model discloses a novel reaction kettle. The reaction kettle comprises a stirrer, a heat-conduction oil inlet pipeline system and a heat-conduction oil outlet pipeline system, wherein the heat-conduction oil inlet pipeline system and the heat-conduction oil outlet pipeline system are connected with the stirrer through pipelines respectively, a steam coil and steel channels are arranged on the stirrer, and the steam coil is fixed on the steel channels through clamps. According to the reaction kettle, the problem of excessively long reaction time caused by the low heating rate of heat-conduction oil is solved, and steam assists in heating in the initial phase of heating, so that the heating rate is increased greatly, the reaction time is shortened, and the production efficiency is improved.
