Selection of ultra-low temperature chiller supporting the glass reactor
In order to achieve an economical ultra-low temperature environment for glass reactors, many customers will not choose multi-stage compressor refrigeration equipment with more than two stages, but use liquid nitrogen. The cost of liquid nitrogen is low, and this refrigeration method is welcomed by some users, both in experiments and in production. However, due to the low boiling point of liquid nitrogen (minus 195.8°C), the latent heat is small and it is easy to evaporate. There are also bi...

Effect of Temperature on Reactions of Chemical Organic Synthesis
Organic synthesis is a common chemical phenomenon in chemistry. Temperature has an important influence on it during the whole synthesis process. As the temperature rises, the heat-absorbing reaction will speed up, resulting in a significant change in the equilibrium constant; once the temperature decreases, The exothermic reaction will be accelerated. Endothermic and exothermic, as the main characteristics of organic synthesis reactions, need to be paid enough attention to by researchers in t...

Points for attention in the selection of industrial heating and cooling machines
In food factories, pharmaceutical factories, biology, new material processing, and chemical plants, the raw materials in the reactor need to be cooled rapidly during the industrial production process involved in the reactor. In order to achieve the purpose of rapid cooling, it is necessary to directly cool down the reactor, so as to achieve the purpose of indirectly reducing the temperature of the material in the reactor. At present, there are about three temperature control schemes for tempe...
