Abstract
ive oxidation of anthracene. Methods\ The operating conditions which influence reaction rate were investigated. Results and Conclusion\ The result of experiments indicates that the yield of anthraquinone over 98% could be obtained through controlling H\-2SO\-4 concentration and temperature at 15% and 68℃ respectively for a stoichiometric amount of K\-2Cr\-2O\-7 reacted for 3 hours.
