    Sodium methoxide

    Sodium methanol is a type of alcohol produced by methanol, CH3ONa, which is used in organic synthesis.
    Sodium methanol is commonly stored in a solution of methanol, ethanol and other alcohol-based solvents.
    Dissolved in ether, the water is dissolved into methanol and sodium hydroxide: CH3ONa + H2O, CH3OH + NaOH
    There are two forms of sodium methanol products: solid and liquid, solids are sodium methanol, and liquid is the methanol solution of methanol sodium, which is 27.5 ~ 31%.
    Liquid methanol sodium is colorless or microyellow viscous liquid, sensitive to oxygen, flammable, explosive.
    Easy to moisture absorption.
    Soluble in methanol and ethanol, decomposed into methanol and sodium hydroxide, under the influence of water in the air at 126.6 ℃ above decomposition.
    It's not soluble in benzene and toluene.
    It has strong irritant, extremely corrosive.
    It is used as A condensation agent and A strong alkaline catalyst, as well as methoxylated agent to make vitamin B1 and A, sulfadiazine and other drugs.
    Small quantities for pesticide production.
    It can also be used as a catalyst for handling fat and cooking oil, especially for lard.
    It can also be used as an analytical reagent.
     
    Solid sodium methoxide is colorless, amorphous powder, sensitive to oxygen, combustible, soluble in methanol, ethanol, decomposed into methanol and sodium hydroxide, under the influence of water in the air at 126.6 ℃ above decomposition.
    It is mainly used in the production of sulfonic drugs, VB6 and VA, and sodium methanol is also an organic synthesis catalyst for pesticide production and oil processing industry.
