A reaction solvent is placed inside the 50L double-layer glass reactor for stirring reaction. The interlayer is mainly used to realize the circulation of cold and heat sources. The interlayer of the double-layer glass reactor can provide high-temperature environment reaction (the maximum working temperature data can reach 300℃): the double-layer glass reactor can also do low-temperature reaction (the low temperature change can reach -80℃): the double-layer glass reactor can be evacuated and do negative pressure reaction, and its unique design makes the experimental research safer and more convenient. When using the double-layer glass reactor, this situation is often encountered on the glass wall, which is mainly manifested in the following aspects:
When the pressure and temperature control are unstable or fluctuate too much, the condensation process of the resin is uneven, which is easy to cause adhesion. Therefore, during the production process, pressure and preheating should be slow. Usually, water vapor of about 0.15MPa is passed for 1 to 4 minutes, and then the pressure is gradually increased. The lifting speed is preferably 0.1~0.15Mpa per minute.
Due to the high sulfate content in urea, when urea is added in the later stage of the resin polycondensation reaction, it is equivalent to adding a curing agent to promote the rapid cross-linking of the resin into a network structure. If it is not handled in time, it will be made into resin. Therefore, standard industrial urea raw materials should be used in production to limit the sulfate content in urea to less than 0.0001.
The 50L double-layer glass reactor is a new type of glass reactor that has been improved on the basis of the single-layer multifunctional glass reactor for many years. It meets the requirements of convenient high and low temperature, rapid heating and cooling, and is a modern synthetic material for laboratories, chemistry, medicine, and heart materials.
The 50L double-layer glass reactor is widely used as a pressure vessel for petroleum, chemical industry, rubber, pesticides, dyes, medicine, sulfide food, nitration, hydrogenation, hydrocarbons, polymerization and condensation
