Application of spectral graph theory on the enthalpy change of formation of acyclic saturated ketones [PDF]

Journal of the Serbian Chemical Society, 2018
The dependence of the enthalpy change of formation of saturated acyclic ketones on molecular structure (the number of carbon atoms, the position of the carbonyl group, and the branching of the molecules) was investigated.

The enthalpies of combustion and formation of thianthrene

Journal of Research of the National Bureau of Standards Section A: Physics and Chemistry, 1975
The enthalpy of combustion of thianthrene (diphenylene disulfide) has been determined in an oxygen-bomb calorimeter. The enthalpy of formation has been derived using data from the available literature. The results obtained are as follows: C 12 H 8 S 2 ( c ) + 17 O 2 ( g ) + 228 H 2 O ( liq ) = 12 CO 2 ( g ) + 2 [ H 2 SO 4 + 115 H 2 O ] ( liq ) Δ
