Hexanitratoammonium cerate

Ceric ammonium nitrate (hexanitratoammonium cerate, G. Frederick Smith Chemical Co.) was made up by weighing in 1.0N HNO3 and was standardized against Fe11. Solutions were generally 0.2-0.8N. 

Isothermal Calorimetry of Hexanitratoammonium Cerate Oxidation of Products from 1-Octene and 10-Undecenoic Acid. The heat developed in the oxidation of ethyl 10-ethoxydecanoate 10-hydroperoxide in ethanol is shown in Figure 1. Samples of 10% solutions of peroxide in ethanol were used with 5-ml. aliquots of 0.1465N cerate in 25 ml. of ethanol. The intersection of the two lines shows a ratio of 1.04 moles of peroxide per equivalent of cerium and maximum heat evolution of 42 kcal. per equivalent of cerium. Similar plots were made for the reaction of the corresponding methoxyhydroperoxide in ethanol (1.10 equivalents, 47 kcal.) and in methanol (1.08 equivalents, 45 kcal.). 1-Ethoxyheptane-1-hydroperoxide was oxidized in acetone (0.98 equivalent, 36 kcal.), in...
