80 °C

In a reactor 0.10 mol hydroquinone (11.0 g.) and 0.10 mol (16.7 g.) N-cyclohexyl-2-pyrrolidone are stirred together at room temperature. An intimate mixture is formed and a 6° C. rise in temperature occurs. The resulting slurry is heated to 80° C whereupon a clear liquid is formed. On cooling in an ice bath, the solution slowly crystallizes to form a magma of the complex compound. The crystals melt at 52°-57° C. This complex is particularly useful as an antioxidant preferably employed in a concentration between about 0.1% and about 5% by weight when employed in a system such as a silverplating bath. This complex is also contemplated for use as an anti-rancidity agent for use with fats and can be suitably incorporated in soaps.
