Description

technical field [0001] The invention relates to the field of chemical synthesis equipment, in particular to a constant temperature control device of a microwave synthesizer. Background technique [0002] Now microwave technology has been used in all aspects of life, such as household microwave ovens, microwave reaction equipment is also widely used in scientific research laboratories. The microwave equipment currently used for scientific research is a traditional standing wave single-mode system, which is characterized by single-channel, one-way, high-density coupling, but the diameter of the single-mode energy interface is small, and the volume of the cavity is limited, and only 10-15ml can be placed in it. Another disadvantage of the container is that the single-mode power is limited by the cavity. Due to the high density and small body, it is easy to produce instantaneous leakage and excessive thermal coupling to damage the reactants, resulting in research failure. Chemi...

The microwave equipment currently used for scientific research is a traditional standing wave single-mode system, which is characterized by single-channel, one-way, high-density coupling, but the diameter of the single-mode energy interface is small, and the volume of the cavity is limited, and only 10-15ml can be placed in it. Another disadvantage is that the single-mode power is limited by the cavity. Due to the high density and small body, it is easy to produce instantaneous leakage and excessive thermal coupling to damage the reactants, resulting in research failure.

The chemical synthesis reaction is sensitive to the temperature requirements, and the temperature control requirements are very high. The rapid temperature rise in a short period of time will cause various side reactions in the reaction in the reactor body. The traditional microwave equipment has low control precision, resulting in impure reaction substances.

The microwave reactor in the traditional microwave equipment is put into the microwave in the static state, and the reaction is carried out in the static state, the reaction speed is slow, and the synthesis efficiency is low.
