Recrystallization temperature and influencing factors?2023/01/12Recrystallization is the process of recrystallizing crystals from a solution or melt after they are dissolved in a solvent or melted. Recrystallization can purify impure substances or separate mixed s...
How to choose the chiller for cooling the mixing tank?2023/01/11Mixing tanks are used in coatings, medicine, building materials, chemicals, pigments, resins, food, scientific research and other industries to stir, mix, blend, and homogenize materials.
What are the system components of various distillation devices?2023/01/091. A complete set of short-path distillation equipment: including short-path evaporator, heating system, feeding system, cooling system, vacuum system, material collection unit, etc.;2. A complete set...
What is the temperature control method of the reactor?2023/01/06The reaction kettle used for temperature control has a large capacity and a thick wall, so it is a controlled object with a large heat capacity and a long pure lag time. As the reaction progresses, th...
Workflow and Equipment Composition of Oil Refining and Dewaxing2023/01/05The oil dewaxing process is based on the melting point difference between the wax and the oil and the solubility of the wax in the oil becomes smaller as the temperature decreases, and the crystalline...
How to control the temperature of solvent recovery by distillation?2023/01/041. If the product quality is not affected by the presence of air at a higher temperature, it can be recovered at normal pressure first, and when the temperature exceeds the normal pressure boiling poi...
Selection of ultra-low temperature chiller supporting the glass reactor2023/02/08In 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 u...
What are the conditions for the decarboxylation reaction? How to control the temperature of heating?2023/01/13The 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 heati...
