Description

Technical Field

[0001] The present application relates to the field of reactors, and in particular to a reactor that is easy to clean. Background Art

[0002] Currently, lithium silylamide polymers are organolithium compounds commonly used for the modification and functionalization of polymer materials, with broad application prospects in the field of materials science. Generally, the production of lithium silylamide polymers requires the use of a reactor.

[0003] A reactor is a device used for chemical reactions that provides a controlled reaction environment, including parameters such as temperature, pressure, and stirring speed. Within the reactor, raw materials can be heated, stirred, and reaction time controlled to ensure a smooth reaction. Furthermore, the reactor can be used to collect and separate products, facilitating subsequent purification and analysis.

[0004] Chinese utility model application number CN202322189554.8 discloses a reactor for facilitating sampling. The reactor comprises a base, the upper surface of which is fixedly connected to the lower surface of the reactor. A delivery pipe is fixedly connected to the lower end of the inner wall of the reactor, the delivery pipe having an on / off valve disposed therein. One end of the delivery pipe is fixedly connected to a sampling tank, the upper surface of which is fixedly connected to a bracket. This utility model solves the problem that most polyether polyol reactors, when in use, are inconvenient to immediately open the reactor for sampling and observation due to the excessively high internal temperature. Sampling and observation can only be carried out after the internal temperature has cooled, making the entire sampling process time-consuming and laborious.

[0005] During use, reactants are likely to remain on the inner wall of an existing reactor to form dirt, which in turn affects the thermal conductivity of the reactor and results in low thermal energy utilization efficiency. Utility Model Content
