METHOD OF PRODUCING BASIC NICKEL (II)-LEAD (II) PHTHALATE Russian patent published in 2012 - IPC C07F15/04 C07F7/24 

FIELD: chemistry.

SUBSTANCE: method involves heating, while stirring continuously in a reaction medium, a mixture of ultrafine nickel hydroxide and phthalic anhydride or phthalic acid, taken in molar ratio 3:1, at temperature 85±5°C for 1 hour. Further, a stoichiometric amount of lead oxide and a catalytic amount of an acetate-containing reactant are then added at temperature 97±2°C. The mixture is heated for 8 hours. The obtained reaction product is separated from the mother solution, washed with water heated to 80°C and then filtered.

EFFECT: method ensures environmental safety of the process, enables to obtain a product having the required catalytic efficiency, increases efficiency of the apparatus by replacing the basic nickel carbonate reactant with nickel hydroxide.
