E.g. chloroformFlammability 1: Must be pre-heated before ignition can occur. Flash point over 93 °C (200 °F). E.g. canola oilInstability 3: Capable of detonation or explosive decomposition but requires a strong initiating source, must be heated under confinement before initiation, reacts explosively with water, or will detonate if severely shocked. E.g. hydrogen peroxideSpecial hazard OX: Oxidizer. E.g. potassium perchlorate

Infobox references

Tetramethylammonium perchlorate is a perchlorate salt with a chemical formula [(CH3)4N]ClO4. It is a white crystalline powder. It is a quaternary ammonium salt. It consists of tetramethylammonium cations [(CH3)4N]+ and perchlorate anions ClO−4.

Preparation

Tetramethylammonium perchlorate can be produced by mixing cold tetramethylammonium hydroxide with cold, dilute perchloric acid, the reaction leads to a white precipitation.[2]

[(CH3)4N]OH + HClO4 → [(CH3)4N]ClO4 + H2O

Uses

The perchlorate is used as an intermediate in organic synthesis, in chromatography and as a supporting electrolyte in electrochemistry.[3] Along with trimethylammonium perchlorate, it was investigated as a component in composite propellants during the Cold War, but without much success.
