Applications

Aliquat 336 is used as a phase transfer catalyst in the catalytic oxidation of cyclohexene to 1,6-hexanedioic acid.^{[citation needed]} This reaction is more environmentally friendly. It is an example of green chemistry, compared with the traditional method of oxidizing cyclohexanol or cyclohexanone with nitric acid^{[citation needed]} or potassium permanganate^{[citation needed]}, which produce hazardous wastes.
