We tried to synthesize the 2-methyl anthraquinone (2-MAQ) with reaction between phthalic anhydride and toluene instead of using 2-methyl phthalic anhydride and benzene. This process didn't generate significant of amount of 1-methyl anthraquinone (l-MAQ) as byproduct. The other advantage of this pathway is using less toxic toluene instead of benzene known as carcinogen. 2-MAQ synthesized this pathway was as effective as reagent grade from commercial available based on soda-anthraquinone(AQ) pulping results.
