METHOD OF PRODUCING ACETYLACETONATES OF PLATINUM GROUP METALS Russian patent published in 2013 - IPC C07F15/00 

FIELD: chemistry.

SUBSTANCE: invention relates to a method of producing acetylacetonates of platinum group metals. The method involves reacting a chloride of a corresponding metal with acetylacetonate, followed by neutralisation of the reaction mixture and separation of the end product. A calculated amount of metal chloride is placed into a container and 0.1 M HCl is added until obtaining a solution with concentration of 0.12-0.15 M by metal. The container with the metal chloride solution is placed into the reactor of a microwave apparatus and exposed to microwaves with power of 100-200 W in order to heat the solution for 15-30 minutes at temperature of 100-120°C. The activated solution is then mixed with acetylacetone in ratio of 1:(3-4) and the mixture is further exposed to microwaves for 5-15 minutes. The reaction mixture is then neutralised to pH 6-7, after which the mixture is further exposed to microwaves for 5-10 minutes and the end product is separated by filtering.

EFFECT: invention simplifies and cuts the duration of the method of producing acetylacetonates of platinum group metals.
