The double-layer glass reactor was a type of equipment used in the fields of chemical engineering, pharmaceutics, and new material synthesis. It could be used for a variety of reactions, such as high-temperature reactions (up to 300 ° C), low-temperature reactions (down to-80 ° C), and vacuum reactions. The inner layer could be filled with a reaction medium for stirring reaction, and the inner layer could be filled with different cold and heat sources (such as freezing liquid, hot water, or hot oil) for circulating heating or cooling reaction. Under the set constant temperature conditions, in a closed glass reactor, the reaction can be carried out under normal pressure or negative pressure conditions according to the requirements, and the reaction solution can be used for recycling and retorting. In some combinations, one or more glass reaction kettles were connected in series to form a reaction device, which could realize the continuity of material reaction. It could also carry out vacuum stirring reaction, constant speed operation mixing reaction, liquid separation, purification and other operations.
