A method is described for the preparation of nickel 2‑ethylhexanoate, which is a precursor of a nanoscale catalyst for the cracking of straight‑run fuel oil, vacuum gas oil, heavy oils, and heavy oil residues. The first step of this method involves the reaction of an aliphatic carboxylic acid with ammonium hydroxide taken in equivalent ratio in water at 20‑65°C for 20‑60 min to give an aqueous solution of the ammonium salt of this carboxylic acid. In the second step, an aqueous solution of a metal chloride is added to the solution of the ammonium salt and the resultant metal salt of the aliphatic carboxylic acid is extracted with an organic solvent. The yield of nickel 2‑ethylhexanoate ranged from 89 to 98% depending on the reaction conditions.
