Methyl trioctyl ammonium chloride CAS 5137-55-3, often referred to as Aliquat 336 or tricaprylylmethylammonium chloride, is a water-insoluble quaternary ammonium compound. It consists of a methyl group and three long octyl chains attached to a positively charged nitrogen atom, paired with a chloride anion. Its unique combination of a hydrophilic ionic center and large hydrophobic alkyl chains makes it a powerful phase-transfer catalyst and an efficient extraction agent in chemical and hydrometallurgical processes.
