Tetramethylammonium perchlorateTetramethylammonium perchlorate is a perchlorate salt with a condensed formula +ClO4−.PreparationTetramethylammonium perchlorate can be produced by mixing cold, dilute perchloric acid with cold tetramethylammonium hydroxide, the reaction will lead to a white precipitation.UsesThe perchlorate is used as an intermediate in organic synthesis, in chromatography and as a supporting electrolyte in electrochemistry. Along with trimethylammonium perchlorate, it was investigated as a component in composite propellants during the Cold War, but without much success.
