Description

technical field [0001] The invention belongs to the technical field related to material synthesis equipment, and more specifically relates to a multifunctional synthesis equipment suitable for metal organic framework materials. Background technique [0002] Metal-organic frameworks (referred to as "MOFs") are a type of organic-inorganic hybrid materials, which are formed by self-assembly of organic ligands and metal salts. There are many types of metal-organic frameworks, and their diverse structures and excellent porous properties make Metal-organic frameworks are widely used in gas adsorption and separation, catalysis, energy storage and other fields. [0003] At present, there are many methods for synthesizing metal organic framework materials, such as ultrasonic method, solvothermal method, stirring method, microwave heating method, etc. Among them, solvothermal method is the most conventional synthesis method, and solvothermal method requires the use of ultrasonic machi...

Problems solved by technology

In addition, after the metal organic framework material is synthesized, impurities in the metal organic framework material need to be removed. This process is called the activation (or purification) of the metal organic framework material. The specific implementation method of the activation process is to use deionized water, organic Solvents (ethanol, acetone, etc.) ultrasonically clean the solid product several times, separate the solid product, and finally dry and separate the solid product. Among them, the process of separating the solid product is relatively difficult. Centrifugation is usually used in the laboratory, but this method takes a long time. , many losses, low yield, not suitable for industrial production; another method is to remove soluble impurities and solvents by filtration, but the filtration speed is extremely slow under normal pressure
