Tetramethylammonium acetate Chemical Properties, Uses, Production
Chemical Properties
clear colorless to pale yellow solution
Uses
Tetramethylammonium acetate is used as an intermediate in organic synthesis, pharmaceuticals, agrochemicals and dyestuffs. Further, it is used to prepare (1R,4S)-4-hydroxycyclopent-2-en-1-essigsaeure-methylester by reacting with 1,3-dimethyl-imidazolidin-2-one. In addition to this, it serves as an emulsifier, catalyst, sterilizer, antistatic and antiseptic agent.

10581-12-1
General procedure for the synthesis of tetramethylammonium acetate from tetramethylammonium hydroxide and glacial acetic acid: 247 mg (4.11 mmol) of glacial acetic acid and 1.50 g (4.11 mmol) of tetramethylammonium hydroxide (25% wt. of methanol solution) were dissolved in 10 mL of methanol. The reaction mixture was stirred at 40°C for 4 hours. Upon completion of the reaction, the reaction solution was filtered and the solvent was subsequently removed using a rotary evaporator to give a viscous oil which gradually solidified. The residual trace solvent was removed under high vacuum to give a white solid product. The white solid was washed with ether and subsequently dried under vacuum to give 480 mg of white solid tetramethylammonium acetate in 87.6% yield.
