Key Properties
Sodium methoxide (extra pure, sodium methylate) is a strong base and a highly reactive alkoxide. It is widely recognized for its role as a transesterification catalyst in the production of biodiesel, where it facilitates the conversion of triglycerides into fatty acid methyl esters. This compound is also utilized in various organic synthesis applications, including the preparation of pharmaceuticals and fine chemicals. Its high purity level of 98% makes it suitable for sensitive chemical reactions and processes that require precise control over reactant quality.
Also known as Sodium Methylate.

- Substance
Sodium methoxide appears as a white to off-white powder that is highly hygroscopic, meaning it readily absorbs moisture from the air. It has a melting point of approximately 150 °C and is soluble in methanol and other polar solvents. The compound is known for its strong alkaline properties, with a pH value that can exceed 14 in solution. Due to its reactivity with moisture, it is essential to handle it in a dry environment to prevent degradation and potential hazards.

Sodium methoxide is primarily used as a catalyst in the transesterification process for biodiesel production, where it helps convert fats and oils into biodiesel and glycerol. Beyond biodiesel, it serves as a strong base in organic synthesis, facilitating reactions such as deprotonation and nucleophilic substitution. It is also employed in the manufacture of various chemicals, including pharmaceuticals, and in the production of biodiesel from renewable resources. Additionally, sodium methoxide is used in the synthesis of methanol derivatives and as a reagent in laboratory settings.
