一般描述

Tetramethylammonium chloride (TMAC) is structurally similar to alkyltrimethylammonium salts. Oxidation of TMAC yields formaldehyde and trimethlamine. It is considered as poor phase-transfer catalyst for most reactions as it is insoluble in organic media. However, it is highly suitable as phase-transfer catalyst for fluorination of chlorobenzaldehydes along with alkali metal fluorides which yield 1,2,2,2-tetrafluoroethyldifluoromethyl ether.

应用

TMAC may be used in ion-exchange procedures to show the increase of pH in understanding the chemical behaviour of catalyst [CTA]Si-MCM-41 using Knoevenagel condensation model.
