The Jacketed glass reactor is designed with double-layer glass. The inner layer can be filled with reaction solvent for stirring reaction, and the inter-layer can be connected to different cold and heat sources for high-temperature or low-temperature reaction, and the high and low temperature integrated machine can also be selected as the temperature control system of the double-layer glass reactor. The double-layer glass reactor is an ideal pilot and production equipment for modern fine chemicals, bio-pharmaceuticals and new material synthesis, and its unique design makes the test more stable and convenient.
Selection of temperature control medium for double-layer glass reactor:
According to the required reaction temperature, temperature control media of different properties are selected as the heat transmission medium of the reaction. For low temperature, choose ice-ethanol bath, for normal temperature, choose water bath, and for high temperature, choose oil bath.
When using low temperature or high temperature, pay attention to choosing the right medium, and the key is viscosity. If the medium is too viscous, the circulating pump may not be able to move, and the medium circulation effect is not good, so the required temperature control effect cannot be achieved. If the high-power circulating pump is replaced rashly, the pressure of the pressing medium is too high, which may cause the damage to the inner lining the rupture of the double-layer glass reactor. Usually the manufacturer will also match the corresponding heating medium for selection according to the glass reactor.
Insulation medium of double-layer glass reactor:
Because the thickness of the inter-layer in the middle of the double-layer glass reactor is small, it has poor thermal insulation performance. In the process of using high temperature and low temperature, it is necessary to use insulation materials to keep the kettle body warm.
The kettle body of the reactor and the pipes for conducting liquids need to be wrapped with insulation materials, and attention should be paid to the thickness of the insulation layer to ensure a better insulation effect.
The working principle of the double-layer glass reactor is to inject high or low temperature circulating liquid through its inter-layer to control the temperature of the experimental materials in the inner layer of the reactor, and has the function of stirring, which can make the reaction of the materials more rapid and uniform.
