Destructive distillation - Wikipedia

Destructive distillation is a chemical process in which decomposition of unprocessed material is achieved by heating it to a high temperature; the term generally applies to processing of organic material in the absence of air or in the presence of limited amounts of oxygen or other reagents, catalysts, or solvents, such as steam or phenols.It is an application of pyrolysis.

8.9: Distillation - Chemistry LibreTexts

Feb 20, 2022 Distillation is a process whereby a mixture of liquids having different vapor pressures is separated into its components. At first one might think that this would be quite simple: if you have a solution consisting of liquid A that boils at 50 C and liquid B with a boiling point of 90 C, all that would be necessary would be to heat the mixture to some temperature between …

Jan 11, 2022 The molecules having higher affinity remain adsorbed for a longer time decreasing their speed of movement through the column. However, the molecules with lower affinity move with a faster movement, thus allowing the molecules to be separated in different fractions. The second type of paper chromatography is the paper partition chromatography.

The definition of an ideal gas is clearly inapplicable to liquids, whose volumes directly reflect the volumes of their component molecules. And of course, the very ability of the molecules to form a condensed phase is due to the attractive forces between the molecules.
