Abstract

The invention relates to an internal-heating high-pressure reaction kettle. The internal-heating high-pressure reaction kettle comprises a reaction tank composed of a reaction tank body and a sealing cover; a single head heating pipe is arranged on the reaction tank body, and is extended into the reaction tank so as to form temperature gradient zones distributed from the center to the periphery in the reaction tank; separating plates are arranged among the temperature gradient zones; quartz rods are arranged on the sealing cover, and are extended downward into the temperature gradient zones; the ends of the quartz rods outside the sealing cover are provided with optical terminals used for observation; reaction change of the temperature gradient zones in the internal-heating high-pressure reaction kettle can be observed via the optical terminals, and recording is carried out based on reaction kettle reaction time; and the reaction tank body and the sealing cover are connected via flanges. Information of a same reaction under different temperatures can be obtained by using the internal-heating high-pressure reaction kettle without increasing equipment.

Description

technical field [0001] The invention relates to a reactor, in particular to an internally heated high-pressure reactor. Background technique [0002] Reactors are widely used in petroleum, chemical, rubber, pesticides, dyes, medicines, food, pressure vessels used to complete vulcanization, hydrogenation, alkylation, polymerization, condensation and other processes, such as reactors, reaction kettles, decomposition pots, polymerization kettle etc. The heating methods of the reactor include electric heating, hot water heating, heat transfer oil circulation heating, external (inner) coil heating, etc., and the cooling methods are jacket cooling and internal coil cooling. [0003] Regardless of the heating method used in the reactor, the chemical reaction process in the reactor is completed at a controlled temperature. Generally, the chemical reaction process is different at different temperatures, and in some cases the difference is quite large. of. [0004] Obtaining reacti...
