Title:
PRODUCTION METHOD OF HYDROGEN PEROXIDE
Document Type and Number:
Japanese Patent JP2017128460
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a production method of hydrogen peroxide capable of recovering a catalyst becoming un-utilizable by scattering of the catalyst caused by agitation, in a hydrogenation reaction step for hydrogen peroxide production using anthraquinone.SOLUTION: Concerning a production method of hydrogen peroxide, in a hydrogenation reaction step for hydrogen peroxide production using anthraquinone, a reactor having a mechanism capable of pouring a solution along an inner wall surface on a furthermore upper part than a reaction liquid surface is used, and while recovering a catalyst adhering onto the inner wall surface of the reactor and becoming un-utilizable to the rection, the reaction is progressed efficiently.SELECTED DRAWING: Figure 1
