1,2-dihydroxy-3-methyl-anthracene-9,10-dione - Introduction

10-Dione (1, 10-dione) is an organic compound with the chemical formula C15H10O4. It is a yellow solid crystal that can be dissolved in ethanol and dichloromethane.

1, 10-dione has important applications in the dye industry. It can be used as a dye intermediate for the preparation of various pigments and dyes. Because of its special structure, it can absorb and scatter specific wavelengths of light, so it is widely used in dyes, pigments and inks.

The method of preparing 1, 10-dione is obtained by reacting anthraquinone with methanol. The specific steps are as follows: first, the Anthraquinone is reacted with excess methanol under alkaline conditions to generate the substrate anthraquinone-9, 10-dimethanol, and then dehydrated by acid catalysis to generate 1, phenanthrene, 10-dione.

Regarding safety information, 1, and 10-dione is a chemical substance, attention should be paid to taking appropriate safety measures. It may irritate the eyes, skin and respiratory system. Protective glasses, gloves and masks should be worn during use. It should also be stored in a dry, cool place, away from fire and oxidizing agents. For unintended contact or ingestion, seek medical help immediately and take the packaging or label to the hospital.
