Procedure

20 g of the low crystalline titanyl phthalocyanine methanol is gradually added after 300 g of chlorobenzene and 30 g of 10% hydrogen peroxide solution is added in the reactor container with divided chambers, followed by mechanically stirring and then refrigerated remaining at −10° C. in one chamber. Next, the solution is successively stirred for 6 hrs and filtered for washing by chlorobenzene and water once respectively. Finally, the titanyl phthalocyanine product is dried at 70° C. under vacuum overnight to obtain 18.5 g of refined titanyl phthalocyanine.
