PROCESS FOR THE EXTRACTION OF HYDROGEN PEROXIDE FROM WORKING SOLUTIONS OF THE ALKYL ANTHRAQUINONE PROCESS

摘要

Hydrogen peroxide is extracted from the working solution of the alkyl anthraquinone process by solvents which are lighter than water and which produce the dispersed phase in the extraction step. The extraction is carried out in unfilled towers which at the bottom are fitted with known elements for dispersing organic liquids, e.g. perforated plates.
