Methyl trioctyl ammonium chloride

Chemical properties

viscous colourless to pale orange liquid

The Uses of Methyl trioctyl ammonium chloride

Methyltrioctylammonium chloride can be used:

• As a catalyst in the synthesis of acridine dione derivatives from aromatic aldehyde, dimedone and amines under ultrasonic irradiations.
• As a catalyst in the synthesis of extended π-systems using aromatic aldehydes and methyldiazines.
• As a component of a catalytic system used in the Suzuki-Miyaura cross-coupling reaction of a variety of aryl and heteroaryl chlorides in H₂O.

The Uses of Methyl trioctyl ammonium chloride

Mixture of C₈ and C₁₀ chains with C₈ predominating. Used as a metal extraction reagent and a phase-transfer catalyst.

Definition

ChEBI: An organic chloride salt having methyltrioctylammonium as the cation.

Flammability and Explosibility

Not classified

Safety Profile

Poison by ingestion and intraperitoneal routes. When heated to decomposition it emits very toxic fumes of NOx, NH3, and Cl-.

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.]
