Abstract
PURPOSE: To obtain clear, high-purity copper phthalocyanine in high yields, by mixing starting materials such as phthalic acid, urea and copper in an org. solvent, heating the mixture and repeating pressurizing and pressure release several times to completel the reaction.
CONSTITUTION: One mol of phthalic acid or its derivative such as phthalimide, 3W5mol of urea or its derivative such as biuret and 0.25W0.3mol of copper or its compd. such as copper chloride are mixed together in an org. solvent such as propylbenzene in an amount ranging 1.5W6 times by weight that of the starting materials. While the mixture is heated at 140W300°C, the mixture is kept under pressure for an appropriate period of time and then the pressure is released to allow the reaction to proceed. By repeating the pressurization and the pressure release several times, water formed by a dehydration reaction is removed and the reaction proceeds smoothly to produce the desired copper phthalocyanine in a short time.
