A type B crystal of 2,3,6,7,10,11-hexahydroxytriphenylene monohydrate was synthesized according to the process described in Synthesis, 477, 1994 and JP-A-8-119894. Namely, 1,2-dimethoxybenzene (31.78 g, 0.23 moles) and anhydrous ferric chloride (120 g, 0.74 moles) were dissolved in 70% sulfuric acid, and the solution was reacted at 25° C. for 24 hours with stirring. After completion of the reaction, the solution was poured into ice water (500 g), and the precipitated crystal was collected by filtration. After the resultant crystal was washed with water (1 L), and then dried to give pale purple colored 2,3,6,7,10,11-hexamethoxytriphenylene (28.2 g, theoretical yield from 1,2-dimethoxybenzene: 90.1%) (the method of Synthesis, 477, 1994).
