The Lydersen method[ 1] is a group contribution method for the estimation of critical properties temperature ( T c ), pressure ( P c) and volume (V c ). The Lydersen method is the prototype for and ancestor of many new models like Joback, [ 2] Klincewicz, [ 3] Ambrose, [ 4] Gani-Constantinou [ 5] and others. The Lydersen method is based in case ...
Acetone (2-propanone or dimethyl ketone) is an organic compound with the formula (CH 3) 2 CO. [22] It is the simplest and smallest ketone (>C=O).It is a colorless, highly volatile, and flammable liquid with a characteristic pungent odour, very reminiscent of the smell of pear drops.
This page contains tables of azeotrope data for various binary and ternary mixtures of solvents. The data include the composition of a mixture by weight (in binary azeotropes, when only one fraction is given, it is the fraction of the second component), the boiling point (b.p.) of a component, the boiling point of a mixture, and the specific gravity of the mixture.

Data obtained from Lange's Handbook of Chemistry, 10th ed. and CRC Handbook of Chemistry and Physics 44th ed. The annotation, d a °C/ b °C, indicates density of solution at temperature a divided by density of pure water at temperature b known as specific gravity. When temperature b is 4 °C, density of water is 0.999972 g/mL. % wt methanol.
