Solubility properties of anthraquinones?
Thread Content
“The anthraquinone process is the main method for producing hydrogen peroxide. The alkylanthraquinone currently in use is mainly 2-ethylanthraquinone (EAQ), and the solvent is usually a mixture of polar and non-polar solvents; the non-polar solvents are typically heavy aromatics (aromatics with C_9~C_11 structures), while the polar solvent is mainly trioctyl phosphate (TOP). ” I would like to ask the following questions: 1. Is EAQ a powder? What is the typical particle size of solid particles? 2. What is the solubility of anthraquinone (EAQ) in this mixed solvent? The specific solubility values? 3. During the process, is EAQ prone to suspension or to settling at the bottom?
1,2-Ethylanthraquinone is pale yellow or bright yellow, appearing as powder or flaky crystals. 2. I also want to know the answer. 3. It tends to settle at the bottom, but when anthraquinone is added to the working solution, the mixing tank remains in constant motion; with a temperature maintained above 50 degrees, it dissolves completely quite quickly.
