High purity Sodium Methoxide powder
-
Formula CH3NaO Cas 124-41-4 Molecular Weight 54.02
Properties: It is a highly alkaline, highly reactive white powder or granule that plays an important role in organic synthesis and industrial catalysis. Its core characteristics are extremely strong alkalinity (stronger than sodium ethoxide and sodium tert-butoxide), small molecular weight, and extremely small steric hindrance, but it is also highly sensitive to moisture and air.

Application:
Industrial catalysis: biodiesel production
Core function: catalyze the transesterification reaction of vegetable oil/animal fat and methanol to efficiently produce fatty acid methyl esters (biodiesel).
Advantages: lower saponification risk than sodium hydroxide (reduce by-products), improve product purity.
Rapid reaction (30–60 minutes), low cost, suitable for large-scale production.
Organic synthesis: strong base driven reaction
Condensation reaction: Claisen condensation (synthesis of β-dicarbonyl compounds), Diekmann cyclization.
α-Alkylation: activate malonic acid esters, acetoacetic acid esters, etc., and construct C-C bonds with halogenated hydrocarbons.
Elimination reaction: promote the dehydrohalogenation of halogenated hydrocarbons to produce olefins (such as acrylonitrile synthesis).
Methoxylation: as a source of methoxyl group (\ce−OCH3\ce−OCH3), synthesize ethers and methyl ether derivatives. Pharmaceutical/pesticide intermediate synthesis
Synthesis of antibacterial drugs (sulfonamides), cardiovascular drugs, and insecticides key modules.
Typical applications: Preparation of p-methoxybenzaldehyde (fragrance, pharmaceutical intermediate).
PACKAGING：
25kg bag; Cardboard drum; Ton bag; 100kg iron drum.
