2-Methylanthracene → Anthracene

Participants

Reaction Steps

A vessel was charged with 4.81 grams of 2-methylanthracene which is 96.7% pure, 50 milliliters of distilled tetrachloroethylene, and 173 grams of a sodium hypochlorite aqueous solution containing 8.04 grams of sodium hypochlorite, providing for a mole ratio of sodium hypochlorite to anthracene of 4.34:1. 4.5 Milliliters of concentrated hydrochloric acid were added to the stirred mixture to adjust the pH to about 7. During the resulting reaction about 12 milliliters of 3 N sodium hydroxide was added to maintain the pH at about 7. Reaction temperature was about 30° C. After about three hours the aqueous layer was removed and the organic layer was found to contain 95% of 2-methylanthraquinone.
