Аннотация:The possibility of improving the procedure for preparing vanadyl phthalocyaninate in a mixture of normal aliphatic hydrocarbons by replacing phthalic anhydride in the starting reactants by phthalimide was evaluated. In the system with phthalimide, the vanadyl phthalocyaninate yield was thus increased by 21% and the synthesis time was decreased by a factor of 3. The formation of vanadyl phthalocyaninate was confi rmed by elemental analysis, IR spectroscopy, X-ray photoelectron spectroscopy, and optical absorption spectroscopy. Vanadyl phthalocyaninate can be effi ciently separated after the synthesis from other system components by dissolution of the product in concentrated H2SO4, followed by precipitation of the metal complex on dilution of the sulfuric acid solution with water.
