Title:
WORKING SOLUTION FOR PRODUCING HYDROGEN PEROXIDE BY MEANS OF ANTHRAQUINONE METHOD AND SOLVENT SYSTEM THEREOF
Document Type and Number:
WIPO Patent Application WO/2023/056957
Kind Code:
A1
Abstract:
A solvent system of a working solution for producing hydrogen peroxide by means of an anthraquinone method. The solvent system comprises the following components or are composed of the following components in parts by volume: A) 2-60 parts of an imide derivative as shown in formula (I); B) 40-98 parts of aromatic hydrocarbon, preferably C9-10 arene; C) 0-20 parts of trioctyl phosphate; and D) 0-20 parts of diisobutylcarbinol. The solvent system has a good solubility to anthraquinone and oxanthranol, a low mutual solubility with water and stable physicochemical properties, meets the use requirements of an anthraquinone process, can significantly improve the production efficiency of a process for producing hydrogen peroxide by means of the anthraquinone method, and has good industrial application prospects.
