PARACHOR Meaning and
Definition
-
Parachor is a term from physical chemistry that refers to a dimensionless quantity used to describe the spreading behavior of a surfactant or surface-active substance on a solid or liquid surface. It is defined as the ratio of the spreading coefficient to the surface tension.
The spreading coefficient represents the difference in interfacial tensions between two immiscible substances, such as a liquid and a solid. It indicates whether a surfactant or liquid will spread or contract on a surface. A positive spreading coefficient suggests spreading, while a negative coefficient signifies contraction or droplet formation.
Surface tension, on the other hand, is a physical property of a liquid that results from the cohesive forces between its molecules. It represents the energy required to increase the surface area of the liquid.
Parachor takes into account both the cohesive forces within the surfactant liquid and the adhesive forces between the liquid and the surface on which it is spread. This dimensionless quantity is used to compare the spreading behaviors of different surfactants or liquids on various surfaces under the same conditions.
Understanding the parachor value of a surfactant is crucial in many industrial applications, such as coating technologies, detergency, and chemical processes, where the ability of a substance to spread evenly and adhere to a surface is important.
