ADOGEN(R) 464 Usage And Synthesis

Chemical Properties

amber viscous liquid at room temperature

Uses

Aliquat 336 is widely utilized as a phase transfer catalyst for the catalytic oxidation of cyclohexene to 1,6-hexanedioic acid. It is involved in the total synthesis of Manzamine A. It serves as an anti-static agent for textile fabrics and carpeting. It finds application in waste water treatment to control foaming. It has a major application as a metal extraction reagent for cadmium, zinc, iron and rare earth metals. It is used as an effective catalyst for the preparation of methylphenyl ether from sodium phenolate with for methyl bromide.

Uses

Quat suitable for nearly all PTC applications without aqueous work-up

Definition

ChEBI: Methyltrioctylammonium chloride is an organic chloride salt having methyltrioctylammonium as the cation. It has a role as a phase-transfer catalyst. It is a quaternary ammonium salt and an organic chloride salt. It contains a methyltrioctylammonium.

Flammability and Explosibility

Not classified

Purification Methods

A 30% (v/v) of Aliquat 336 solution in *benzene is washed twice with an equal volume of 1.5M HBr. [Petrow & Allen, Anal Chem 33 1303 1961.] It is purified by dissolving 50g in CHCl3 (100mL) and shaking with 20% NaOH solution (200mL) for 10minutes, and followed by 20% NaCl (200mL) for 10minutes. It is then washed with a small volume of H2O and filtered through a dry filter paper [Adam & Pribil Talanta 18 733 1971]. n-Alkylammonium chloride n=2,4,6. Recrystallise them from EtOH or an EtOH/Et2O mixture. [Hashimoto & Thomas J Am Chem Soc 107 4655 1985, Chu & Thomas J Am Chem Soc 108 6270 1986.] n-Alkyltrimethylammonium bromide n=10,12,16. Recrystallise them from an EtOH/Et2O mixture. [Hashimoto & Thomas J Am Chem Soc 107 4655 1985.]
