Enthalpies of combustion and formation of 1,4-dihydro-1,4-epoxynaphthalene. Havel, James J.; Montgomery, Robert L.; Lau, Ching-Ching; Grissom, Martin (Dep. Chem., Rice Univ., Houston, Tex., USA). J. Chem. Eng. Data, 23(2), 132-3 (English) 1978. CODEN: JCEAAX. ISSN: 0021-9568. DOCUMENT TYPE: Journal CA Section: 69 (Thermodynamics, Thermochemistry, and Thermal Properties) Measurement was made of the enthalpy of combustion of 1,4-dihydroxy-1,4-epoxynaphthalene C10H8O (crystal) [573-57-9]. The std. enthalpies of combustion and formation were calcd. for 298.15 K: DHc° = -5140.5 ± 5.7 kJ mol-1, DHf° = 62.1 ± 5.8 kJ mol-1. The enthalpy of decompn. at 298.15 K of this solid compd. into solid naphthalene and gaseous mol. oxygen was calcd. to be DH° = 3.82 ± 1.41 kcal mol-1, and, into solid naphthalene and gaseous at. oxygen, DH° = 63.4 ± 1.4 kcal mol-1.
