Latest Patents

Lizhu Chen holds a patent for a novel method of preparing 3,3′-diaminobenzidine. This method involves several critical steps, starting with the esterification reaction of 4,4′-biphenol and N,N-dimethylsulfamoyl chloride in a specified solvent at temperatures ranging from 40 to 70 degrees Celsius. The process results in a first intermediate, 4,4′-biphenyl bis(N,N-dimethylaminosulfonate), which then undergoes chlorination under acidic conditions to form a second intermediate. Through further ammonolysis reactions with a carefully chosen catalyst, the raw product is refined to yield a purified final product. This innovative approach not only improves the purity of the end result but also minimizes the pollution typically associated with such chemical processes.
