Abstract
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 confirmed by elemental analysis, IR spectroscopy, X-ray photoelectron spectroscopy, and optical absorption spectroscopy. Vanadyl phthalocyaninate can be efficiently 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.
期刊介绍：
Russian Journal of Applied Chemistry (Zhurnal prikladnoi khimii) was founded in 1928. It covers all application problems of modern chemistry, including the structure of inorganic and organic compounds, kinetics and mechanisms of chemical reactions, problems of chemical processes and apparatus, borderline problems of chemistry, and applied research.
