Description

technical field [0001] The invention belongs to the technical field of hydrogen peroxide preparation, and in particular relates to a multifunctional microfluidic chip reaction device for preparing hydrogen peroxide. Background technique [0002] Hydrogen peroxide is a common name for hydrogen peroxide. Its appearance is a colorless transparent liquid. Its aqueous solution can be used for wound disinfection, environmental disinfection and food disinfection. As a common oxidant, the only product of hydrogen peroxide in the reaction process is water. It is recognized as a green and clean chemical product and has been widely used in chemical synthesis, papermaking, printing and dyeing industries. With the continuous development of economy and society, the demand for hydrogen peroxide is increasing both domestically and internationally. [0003] The anthraquinone method is usually used in the industry to prepare hydrogen peroxide, and the hydrogen peroxide produced by the anthra...
