Cupric Nitrate Trihydrate

Dissolve 15-0 g. of A.R. barium nitrate and 130 g. of A.R. cupric nitrate trihydrate in 450 ml. of water at 80°. Prepare a solution of sodium chromate by dissolving 89 g. of recrystallised sodium dichromate dihydrate in 200 ml. of water and adding 112 5 ml. of cone, ammonia solution (sp. gr. 0-90). Add the warm solution (80°) of nitrates in a thin stream, with stirring, to the sodium chromate solution (at 25°). Collect the orange precipitate by suction Bltration, wash it with two 50 ml. portions of 5fiter, drain well, and dry at 75-80° for 12 hours powder finely.

Copper chromite (Lazier catalyst). Supplier Harshaw (CU-0202P 556-002). For preparation of the catalysC an aqueous solution of barium nitrate and cupric nitrate trihydrate is stirred during addition of a solution of ammonium chromate, prepared from ammonium dichromate and aqueous ammonia. The reddish brown precipitate of copper barium ammonium chromate is washed and dried and decomposed by heating in a muffle furnace at 350-450 . The ignition residue is pulverized, washed with 10% acetic acid, dried, and ground to a fine black powder. 

A MIXTURE of 26 g. (o.i mole) of c.p. barium nitrate and 800 cc. of distilled water is warmed to 70°. After solution is complete 218 g. (0.9 mole) of CJ. cupric nitrate trihydrate is added and the mixture stirred at 70° until a clear solution results... 

CUPRIC NITRATE TRIHYDRATE (3251-23-8) A strong oxidizer. Violent reaction with reducing agents, combustible materials, acetic anhydride, ethers, potassium ferrocyanide, finely divided tin. The aqueous solution is a medium-strong acid. Incompatible with bases, acetylene, ammonia, aliphatic amines, alkanolamines, amides, alkylene oxides, cyanides, epichlorohydrin, esters, isocyanates, organic anhydrides, vinyl acetate. Attacks metals in the presence of moisture. 

In basic methodology reminiscent of the formation of anisaldehyde from 4-methoxytoluene and also an aspect of phenol oxidation (Chap. 5), 2-cresoi in methanol containing sodium hydroxide and a catalytic quantity of tetrakis(2,4-dimethoxyphenyl)porphyrinatoiron(lll) chloride and cupric nitrate trihydrate afforded a 78% yield of salicylaldehyde after oxygenation with oxygen... 

In a 1-L pear-shaped evaporating flask, were added 26 g cupric nitrate trihydrate and 400 mL acetone, and the mixture was vigorously stirred for 5 min. KIO clay (30 g) was then added, and stirring was continued for another 5 min. Then acetone was removed by rotary evaporation on a water bath at 50°C. After a dry solid crust adhered to the walls of the flask was flaked off with a spatula, and the rotary drying under vacuum was resumed for 30 min at the same temperature. This yielded the clay-supported cupric nitrate as a blue free-flowing powder.

The anhydrous salt can be prepared by dissolving copper metal in a 1 1 mixture of liquid NO2 and ethyl acetate and purified by sublimation [Evans et al. J Chem Soc, Faraday Trans 1 75 1023 7979]. The hexahydrate dehydrates to the trihydrate at 26°, and the anhydrous salt sublimes between 150 and 225°, but melts at 255-256° and is deliquescent.
