Sodium methoxide (CAS 124-41-4) is a chemical compound with the formula CH3ONa. This colorless solid, which is formed by the deprotonation of methanol, is a widely used reagent in industry and the laboratory. It is also a dangerously caustic base.

　　Sodium methoxide is prepared by carefully treating methanol with sodium. The reaction is so exothermic that ignition is possible. The resulting solution, which is colorless, is often used as a source of sodium methoxide, but the pure material can be isolated by evaporation by heating to remove residual methanol. The solid and especially solutions absorb carbon dioxide from the air, thus diminishing the effectiveness of the base.

　　Application

　　Organic synthesis

　　Sodium methoxide is a routinely used base in organic chemistry, applicable to the synthesis of numerous compounds, ranging from pharmaceuticals to agrochemicals. As a base, it is employed in dehydrohalogenations and various condensations. It is also a nucleophile for the production of methyl ethers.

　　Industrial application

　　Sodium methoxide is used as an initiator of anionic addition polymerization with ethylene oxide, forming a polyether with high molecular weight. Biodiesel is prepared from vegetable oils and animal fats, that is, fatty acid triglycerides, by transesterification with methanol to give fatty acid methyl esters (FAMEs). This transformation is catalyzed by sodium methoxide.

　　Medical use

　　Mainly used in pharmaceutical industry such as the manufacture of vitamin A1,Vitamin B1,sulfadiazine,trimethoprim and so on,as well as in biodiesel industry.

　　Other use

　　It also can be used as the edible catalyst and the analytical reagent.
