Description


Linear alkylbenzene sulfonic acid is the largest-volume synthetic surfactant because of its relatively low cost, good performance, the fact that it can be dried to a stable powder and the biodegradable environmental friendliness as it has straight chain. LABSA is an anionic surfactants with molecules characterized by a hydrophobic and a hydrophilic group. It is complex mixtures of homologues of different alkyl chain lengths (C*0 to C*3 or C*4) and phenyl positional isomers of  2 to *-phenyl in proportions dictated by the starting materials and reaction conditions, each containing an aromatic ring sulfonated at the para position and attached to a linear alkyl chain at any position with the exception of terminal one (*-phenyl). The properties of LABSA differ in physical and chemical properties according to the alkyl chain length, resulting in formulations for various applications. The starting material LAB (linear alkylbenzene) is produced by the alkylation of benzene with n-paraffins in the presence of hydrogen fluoride (HF) or aluminium chloride (AlCl3) as a catalyst.  LABSA is produced by the sulfonation of LAB with oleum in batch reactors. Other sulfonation alternative reagents are sulfuric acid, diluted sulfur trioxide, chlorosulfonic acid and sulfamic acid on falling film reactors. LABSA are then neutralized to the desired salt (sodium, ammonium, calcium, potassium, and triethanolamine salts).
