Properties and stability
1. Basic properties: Easily decomposes when exposed to light and moisture in the air. It decomposes into methanol and sodium hydroxide when meeting water. It reacts with methanol to form CH3ONa·2CH3OH (white powder).
2. The methanol in sodium methoxide solution is highly toxic. Sodium methoxide is highly corrosive and can irritate the eyes and nose. Inhaling high-concentration vapor can cause strong irritation. In severe cases, it can affect breathing and cause dizziness, which can be recovered with rescue. However, inhaling high-concentration vapor for a long time can cause pulmonary edema and death. Inhalation of vapors and contact with skin should be prevented. In addition, safety measures should be paid attention to during the production process, equipment should be sealed, and operators should wear protective equipment.
Storage method
1. Storage: sealed and stored in a cool, dry and dark place
2. Sealed and packed in iron drums, 200kg per drum, stored in a cool, ventilated and dry place, fireproof and heat-proof ,Protect
from the sun. Store and transport according to regulations on flammable chemicals.
Synthesis method
Brief description of the production method: The industrial product is usually a methanol solution of sodium methoxide (the content is generally 23%).�� is obtained by reacting methanol with sodium hydroxide, and adding benzene at the same time for azeotropic distillation, so that benzene, methanol, and water form a ternary azeotrope. After removing the water generated during the reaction, the benzene is evaporated.
Purpose
1.Uses: Mainly used as raw materials for medicines and pesticides, and also used in dye and chemical fiber industries. Organic synthesis
2. Mainly used as condensation agent and strong alkaline catalyst, and methoxylating agent for producing vitamin B1 and A, Sulfadiazine and other drugs. A small amount is used in pesticide production. It can also be used as a catalyst for processing edible fats and oils (especially lard). It can also be used as an analytical reagent.
