Description

Acid slurry or alkyl benzene sulphonate, commonly known as Linear ALKYL Benzene Sulphonate (LABSA) is made by sulphonation of linear alkyl benzene with a suitable sulphonating agent.
Since it is miscible with water and has a low salt content, it is the most important raw material for producing anionic surfactants, it is extensively used in the manufacture of synthetic washing detergent powders, cakes and liquids, as well as soaps.
This major industrial surfactant is used in formulating various types of household and industrial detergents and also acts as an emulsifier in agricultural herbicides and pesticides.
Acid slurry is neutralized by slow addition of caustic soda solution, keeping the pH between 7 to 9.
