Sistema di controllo della temperatura di prova dell'antigelo per autoveicoli
When it comes to car antifreeze, we all know that its main function is to prevent the coolant from freezing and cracking the radiator and freezing the engine cylinder block or cover when we stop in the cold winter. Make the cooling system in the best working condition and ensure the normal working temperature of the engine. The freezing point of water is 0°C, and ordinary antifreeze can reach -40°C, while high-quality antifreeze should be able to reach about -60°C, and the antifreeze has a h...

Informazioni sulle dimensioni e sull'altezza di installazione delle apparecchiature del sistema di controllo della temperatura di riscaldamento a refrigerazione
Whether it is biopharmaceutical, traditional Chinese medicine or chemical pharmacy, pharmaceutical companies are all related to chemistry, because the extraction and synthesis of pharmaceutical ingredients are all in the form of chemical products. Therefore, as long as there are many links in the process, there are explosive substances such as acetone, alcohol, etc. There are also raw materials in the warehouse, dust in the workshop, and pressure in the reactor. Temperature control equipment...

Scelta del refrigeratore a bassissima temperatura per il reattore in vetro
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...

Effetto della temperatura sulle reazioni della sintesi chimica organica
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...

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...

Quali sono le condizioni della reazione di decarbossilazione e il controllo della temperatura di processo?
The decarboxylation of aromatic acids is easier than that of fatty acids. For example, benzoic acid can be decarboxylated by adding a little copper powder as a catalyst in quinoline solution and heating. When a strong electron-withdrawing group is attached to the α-C of the carboxylic acid, heating can make it decarboxylate more smoothly. For example: when the ortho-diaromatic organic acid is heated, it is easy to remove a carboxyl group, but when the temperature is low, an acid anhydride w...
