Acetanilide is an organic compound with the chemical formula of C8H9NO, which is colorless and shiny lobular solid or white crystalline powder. It is the raw material of sulfonamides and can be used as analgesic, antipyretic, preservative and dye intermediate.
Cyclopropyl methyl ketone is a chemical substance with the molecular formula of C5H8O.
Sodium methoxide is an extremely hazardous chemical that is both corrosive and prone to spontaneous combustion. It is mainly used in pharmaceutical industry, as condensation agent or chemical reagent in organic synthesis, catalyst for edible oil treatment, etc. Sodium methoxide has extensive applications, mainly used in the production of sulfonamides. Sodium methoxide is also a catalyst for organic synthesis, which is used in pesticide production and oil processing industry.
Acetanilide process flow: Acetanilide is obtained by acylation and rectification of aniline and glacial acetic acid. Uses: Mainly used as raw materials for the production of medicines, dyes and other organic products.
The physical and chemical properties of sodium methoxide
Sensitive to air and moisture, decomposes into methanol and sodium hydroxide rapidly when meeting water, and decomposes in air above 126.6°C.
Process flow of liquid sodium methoxide
Produced by continuous method. Solid sodium hydroxide is dissolved in methanol. After dissolving, it is precipitated and clarified to remove solid impurities. The clear liquid is pumped into the top of the reaction dehydration tower, and refined methanol vapor enters the tower from the bottom of the tower. After continuous reaction and dehydration, the product is obtained from the bottom of the tower. The water-containing methanol vapor comes out from the top of the tower and enters the rectification system for refining, and the anhydrous methanol vapor returns to the bottom of the tower.
The impact of sodium methoxide on the environment
Health Hazard Routes of entry: inhalation, ingestion, and percutaneous absorption.
