| | Potassium methoxide Usage And Synthesis |
| Chemical Properties | solid | | Uses | Potassium methoxide is used as a chemical intermediate. It is also used in biodiesel production and in fuel additives. It acts as a catalyst for the preparation of methyl formate and an alkaline catalyst for dimethyl formamide. Further, it is used as versatile reagents in chemical reactions such as condensation, esterification, alkoxylation and etherification, Claisen condensation, Wolf-Kishner reduction and Stobbe reaction. | | Fire Hazard | Flammable solid, igniting in moist air. Rapid
addition in bulk amount into halogenated
solvents may cause an explosion. Reaction
with arsenic pentafluoride in benzene can
result in explosion (Kolditz 1965). | | Flammability and Explosibility | Flammable |
