Procedure

About 0.237 grams (2.15 millimoles) pyrocatechol and 0.288 grams (2.35 millimoles) methylhydroquinone are dissolved in 56 milliliters of distilled water in a 500 ml Erlenmeyer flask. Subsequent additions of 66 ml hydrazine hydrate (64% N2H4 by weight) and of 2.62 ml of an aqueous solution containing 20% CoCl2 · 6H2O (corresponding to 2.2× 10-3 g atom of Co++ion) give a clear, orange-red solution containing approximately 35% hydrazine and 0.6% of catalyst by weight (molar ratio pyrocatechol/cobalt of approximately 1.0).
