Sodium methoxide is also known as sodium methoxy. It is a kind of alkoxide salt produced by methanol, the chemical formula is CH3ONa, which is a strong base commonly used in organic synthesis. Sodium methoxide is usually stored in a solution of alcohol-based solvents such as methanol and ethanol. Dissolved in ether to form a suspension, sensitive to moisture, decomposition into methanol and sodium hydroxide in water: CH3ONa+H2O→CH3OH+NaOH sodium methoxide products have two forms: solid and liquid, solid is pure sodium methoxide, liquid is methanol solution of sodium methoxide, sodium methoxide content 27.5~31%. Liquid sodium methoxide is a colorless or yellowish viscous liquid, sensitive to oxygen, flammable, explosive. It is easy to absorb moisture. Soluble in methanol and ethanol, decomposing into methanol and sodium hydroxide in water, in 126. Chemicalbook decomposes in air above 6 °C. Insoluble in benzene and toluene. It has strong irritation and is extremely corrosive. It is used as a condensing agent and a strong basic catalyst, as well as a methoxylating agent for the preparation of vitamin B1 and A, sulfadiazine and other drugs. A small amount is used for pesticide production. It can also be used as a catalyst for the treatment of edible fats and edible oils, especially lard. It can also be used as an analytical reagent. Solid sodium methoxide is a colorless amorphous powder, sensitive to oxygen, flammable, soluble in methanol, ethanol, decomposing into methanol and sodium hydroxide in water, decomposing in air above 126.6 °C. Mainly used in the production of sulfonamides, VB6 and VA, sodium methoxide is also a catalyst for organic synthesis for pesticide production and oil processing industries. |
