Novel sample container for solution calorimetry

Review of Scientific Instruments, 1979
A new design for calorimeter sample containers is described. The basic design is a hollow right cylinder with thin, glass membranes covering both ends. The membranes are intended to be broken out completely to release the sample contained within. The membranes are sealed to the container body with silicone rubber.

Solution Calorimetry Under Hydrothermal Conditions

Reviews in Mineralogy and Geochemistry, 2013
The first quantitative studies of the thermodynamics of hydrothermal solutions were made in 1903 by A.A. Noyes and W.D. Coolidge (1903), who used the change in conductance associated with ionization to measure the ionization constants of water and aqueous acids and bases up to about 300 °C at steam saturation.

Solution calorimetry of nitrosonium salts

Journal of the Chemical Society, Dalton Transactions, 1980
The standard enthalpies of formation of crystalline [NO][ClO4], [NO][HSO4], and [NO]2[S2O7] have been determined as 59.0, –680.3, and –1 041.0 kJ mol–1 respectively, based on enthalpies of reaction with aqueous base. The discrepancies between these and some previously published values are discussed in terms of the competing neutralisation and ...

Isoperibol Reaction-Solution Calorimetry

2008
The determination of enthalpies of reaction in solution, using isoperibol reaction-solution calorimetry, is often the easiest and most accurate method of determining enthalpies of formation of compounds that cannot be studied by combustion calorimetry.

Applications of Calorimetry to Nonelectrolyte Solutions

Journal of Chemical & Engineering Data, 1996
This paper describes the application of calorimetry to the measurement of the excess molar enthalpies for binary mixtures of nonelectrolytes. Batch, displacement, and flow calorimeters are described, using as examples the batch calorimeter of McGlashan;, the displacement calorimeters of Van Ness and of Marsh and Stokes, and the flow calorimeters of ...

An investigation of calibration methods for solution calorimetry

International Journal of Pharmaceutics, 2004
Solution calorimetry has been used in a number of varying applications within pharmaceutical research as a technique for the physical characterisation of pharmaceutical materials, such as quantifying small degrees of amorphous content, identifying polymorphs and investigating interactions between drugs and carbohydrates or proteins and carbohydrates.
