An overview of some basic mathematical techniques for data correlation is to be found herein together with background on several types of physical property correlating techniques and a road map for the use of selected methods. Methods are presented for the correlation of observed experimental data to physical properties such as critical properties, normal boiling point, molar volume, vapor pressure, heats of vaporization and fusion, heat capacity, surface tension, viscosity, thermal conductivity, acentric factor, flammability limits, enthalpy of formation, Gibbs energy, entropy, activity coefficients, Henry s constant, octanol—water partition coefficients, diffusion coefficients, virial coefficients, chemical reactivity, and toxicological parameters. 

Many other properties have been found to show periodic variations and these can be displayed graphically or by circles of varying size on a periodic table, e.g. melting points of the elements, boiling points, heats of fusion, heats of vaporization, energies of atomization, etc. Similarly, the properties of simple binary...

This concept presumes that the calorific input of the fire may be partly absorbed by the endothermic changes of the mineral substances employed in the formulation of the mastic. Thus, for example, such latent heat as the heat of fusion, heat of vaporization, heat of sublimation, and heat of transition (the heat required to change a unit mass of a given substance from one crystalline structure to another) all can absorb considerable energy which would otherwise be used to raise the combustible substrate to an ignition point. The efficiency of these fire-resistant minerals can also be adjudged by their specific heat values.

The latent heat of fusion (heat absorbed) is 2-4 Cals., the latent heat of solution of the crystals from -0-2 to -0-17 Cals., and of the fused acid from + 2-2 to + 2-14 Cals, (per mol in each case).

Place 50 mg of powdered iron(II) sulfate (this is a large excess) in a 10 X 75 mm test tube, add 0.5 mL of the alkaline solution from the fusion, heat the mixture gently with shaking to the boiling point, and then—without cooling—acidify with dilute sulfuric acid (hydrochloric acid is unsatisfac-...
