Products Description
Introduction and application of CAS：442912-79-0|MIL-53(Cr)
A simple method of synthesizing metal machine frame material MIL‑53 (Cr), a method of synthesizing metal machine frame material MIL‑53 (Cr).
To solve the problem, the existing MIL-53(Cr) can only be synthesized through hydrothermal method, which takes a long time and uses toxic fluorine elements. A large amount of solvents are used in the synthesis process, and the hydrothermal method to prepare MIL-53(Cr) The specific surface area is small, and a post-processing step of high-temperature calcination is required to purify the product.
1. Add chromium chloride hexahydrate into a polytetrafluoroethylene-lined stainless steel reactor and heat it, then add terephthalic acid and ultrasonic, crystallize to obtain a solid;
2. Use absolute ethanol and N,N-dimethylformamide to wash the solid respectively, and separate it by suction filtration to obtain the solid after one wash;
3. Repeat step 2 to wash the solid after washing once to obtain the washed solid;
4. Dry the washed solids.
