7-Methylanthracene - Reference Information
| EPA chemical substance information | information provided by: ofmpeb.epa.gov (external link) |
| Use | with 2-methyl anthracene and anthracene, dimethyl anthracene as raw materials, Copolymerization of synthetic resin, can be used as coatings, plastic, but also can be used as fluorescent agents and reagents. |
| production method | with anthracene oil as raw material, cut off the fraction at 352-365 ℃ by rectification, add the fraction into industrial ethanol, after being dissolved by heating, the mixture was left to cool to 50 ° C., and impurities were filtered off. The filtrate was continued to cool to room temperature and filtered. The filter cake was filtered by adding 10% sulfuric acid to Ph 2-3, and then the filter cake was filtered by adding 10% sodium hydroxide solution to pH 7-8. The crystals obtained are recrystallized from pyridine, or continue to recrystallize from ethanol, or continue to recrystallize from ethanol, 2-methylanthracene having a melting point of 200.5-203 °c. |
