실험 절차

47.3 Grams of cyclohexylamine is mixed with 50 g of dimethyl 2,2'-azobis (2-methylpropionate) and 20 g of 28% sodium methoxide solution in methanol is dropwise added thereto under stirring, following by conducting a reaction at room temperature with stirring for 6 hours and keeping standing overnight. 100 Milliliter of water is added to the reaction solution and cooled to 10° C. to precipitate crystals. The crystals are recovered by filtration and dried to give 59.4 g (yield 81 %) of 2,2'-azobis (N-cyclohexyl-2-methylpropionamide) as yellow crystals. The solubility is shown in Table 1.
