Procedure
A solution of zinc chloride (26.65 g; 0.1956 mole) in water (26.65 g) was added rapidly to an agitated solution of potassium hexacyanocobaltate (13.00 g, 0.0391 mole) in water (263.35 g). The potassium hexacyanocobaltate solution was maintained at 40° C. during addition of the zinc chloride solution. A colorless precipate of zinc hexacyanocobaltate particles formed immediately upon addition. After stirring for 15 minutes at 40° C., dimethoxyethane (84.00 g; 0.9321 mole) was added to the aqueous catalyst slurry. The resulting mixture was stirred for an additional 30 minutes and the zinc hexacyanocobaltate zinc chloride dimethoxyethane water complex catalyst recovered by filtration using a horizontal basket centrifugal filter and a light weight nylon fabric filter medium. After washing with 300 mL dimethoxyethane and drying in air at ambient temperature and pressure, the filter cake obtained was quite soft and could be easily crushed to a fine powder.
