Tetramethylammonium perchlorate is a perchlorate salt with a condensed formula [N(CH3)4]+ClO4−.
Preparation
Tetramethylammonium perchlorate can be produced by mixing cold, dilute perchloric acid with cold tetramethylammonium hydroxide, the reaction will lead to a white precipitation.{{cite journal |last1=Juknelevicius |first1=Dominykas |last2=Dufter |first2=Alicia |last3=Rusan |first3=Magdalena |last4=Klapötke |first4=Thomas M. |last5=Ramanavicius |first5=Arunas |title=Study of Pyrotechnic Blue Strobe Compositions Based on Ammonium Perchlorate and Tetramethylammonium Nitrate: Study of Pyrotechnic Blue Strobe Compositions Based on Ammonium Perchlorate and Tetramethylammonium Nitrate |journal=European Journal of Inorganic Chemistry |date=2017-02-17 |volume=2017 |issue=7 |pages=1113–1119 |doi=10.1002/ejic.201601486|doi-access=free }}
Uses
The perchlorate is used as an intermediate in organic synthesis, in chromatography and as a supporting electrolyte in electrochemistry.{{cite web | url=https://www.alfa.com/ru/catalog/030834 | title=2537-36-2 - Tetramethylammonium perchlorate - 30834 - Alfa Aesar }} Along with trimethylammonium perchlorate, it was investigated as a component in composite propellants during the Cold War, but without much success.
