Tetrabutylammonium hydrogen sulfate Usage And Synthesis

Chemical Properties

white powder

Uses

Displays antibacterial properties due to the presence of the quaternary amine and the counter ion.

Uses

A compound that displays antibacterial properties

Uses

Phase transfer catalyst Tetra-n-butylammonium hydrogen sulfate shows antibacterial properties due to the presence of the quaternary amine and the counter ion. It serves as a phase-transfer catalyst, surface-active agent, solvent, intermediate, active ingredient for conditioners, antistatic agent, detergent sanitizers, softener for textiles and paper products, emulsifying agents and pigment dispersers. It is used as an efficient catalyst in the N-alkylation reactions of benzanilides, cyclization of beta-amino acids to beta-lactams, conversion of nitriles to amides, dehydrohalogenation of aryl 2-haloethyl ethers to give vinyl ethers and in the oxidation of alcohols.

General Description

Tetrabutylammonium bisulfate, a quaternary ammonium salt, is a phase-transfer reagent.

Purification Methods

The sulfate crystallises from acetone. It has been used as a phase transfer catalyst.
