Involatile

In the context of chemistry and related fields, 'involatile' describes a substance or compound that does not readily vaporize or change from a solid or liquid state into a gaseous state under normal conditions of temperature and pressure. This lack of volatility is often due to strong intermolecular forces between the molecules, such as ionic bonds or strong hydrogen bonds, which require a significant amount of energy to overcome. involatile substances have high boiling points and low vapor pressures. This characteristic impacts their use in a variety of applications, from creating stable solutions to serving as non-reactive components in chemical reactions.

Involatile meaning with examples

• Salt (sodium chloride) is an involatile compound. When heated, it does not readily evaporate like water; instead, it remains a solid at high temperatures, making it suitable for applications requiring a stable, non-vaporizing ingredient in chemical reactions. Its involatility contributes to its use in preserving food as well.
• Glycerin, used in many cosmetic products, is an involatile substance. Due to its high boiling point, it remains a liquid and doesn't evaporate easily, making it effective as a humectant, attracting moisture from the air to keep skin hydrated, and contributing to product stability.
• During the distillation of a mixture, involatile components, like sand or larger organic molecules, are left behind. This is because they lack the ability to vaporize at the boiling point of other components, allowing for their separation from the more volatile substances.
• Many high-boiling-point oils and fats are considered involatile. This property is utilized when cooking at high temperatures; the oils do not produce excessive fumes or vapors. This ensures the food is cooked without the presence of volatile byproduct, such as acrolein.
• In the manufacture of certain paints, involatile pigments are chosen for their stability and longevity. The pigment particles remain solid over the product's life, ensuring color retention and preventing the paint from fading or changing consistency due to evaporation.
