General description

Ammonium lauryl sulfate is an anionic surfactant consisting of a nonpolar hydrocarbon chain and a polar sulfate end group. It is used as a foaming agent, and as a detergent in many industrial applications.

Application

Ammonium lauryl sulfate can be used as:      
  • A catalyst in the synthesis of 1H-benzo[d]imidazole, quinoxaline, and 2,3-dihydro-1H-benzo[b][1,4]diazepine derivatives by reacting with benzene-1,2 diamine and aromatic aldehydes/1,2-diketones/ketones respectively.     
  • A corrosion inhibitor for carbon steel and copper in acidic solution.   
  • A surfactant in the fabrication of porous ceramics by gel casting.
