What are the conditions for the decarboxylation reaction? How to control the temperature of heating?
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 wi...

Disadvantages and advantages of general heat transfer oil heating circulation system
The heat conduction oil heating circulation system adopts a fully closed loop structure to directly act on the heat energy to the heated medium. Its advantages are: (1) Due to the continuous renewal of the heat transfer surface, the heat loss is small; (2) The temperature field distribution state of the medium can be changed during operation; (3) Multiple units can be used in parallel. The closed circulation system has a wide range of applications, such as various boilers, industrial furnaces...

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...
