Linear Alkyl Benzene

Linear Alkyl Benzene (C6H5CHR1R2) is a clear colourless liquid with characteristic odour. It is most widely used as the basic raw material for the manufacture of synthetic detergent. The linear alkyl Benzene produced from the C10 – C13 or C11 – C14 linear mono olefins are useful detergent Intermediate and can be readily sulphonated to yield linear alkyl benzene sulphonates. These compounds constitute the “active” ingredients of many house hold detergents. They are surface active compounds (surfactants) which are combined with various builders (often inorganic salts) to make up a detergent formula. Linear alkyl benzene (LAB) is the basic raw material for production of most widely used detergent. Linear alkyl benzene was introduced as substitute for non biodegradable branched alkyl benzene.

Uses :
Linear Alkylbenzene Sulphonic Acid is extensively applied anionic surfactant. It is raw material for detergent industry characterized by detergency, foam, moisture, and emulsion and dispersing. The material performs well in deep underwater environments.  One study suggested LAB as a suitable material to be employed in a Secret Neutrino Interactions Finder (SNIF), a type of antineutrino detector designed to detect the presence of nuclear reactors at distances of between 100 and 500 km.
