Storage method
This product should be sealed, dry and protected from light.
Synthesis method
Combine methyl salicylate and 25% ammonia in 20℃ Stir closedly 3h, and then in30-40℃Stir5h. Cool and acidify the reaction solution to pH3-4, and salicylic acid crystals will precipitate. In industrial production, sodium metabisulfite can also be added to the aqueous solution of salicylic acid, and then passed through the ammonia reaction. The yield is 90% and above.
Purpose
for organic synthesis. Medical research. Anticorrosive.
This product is an antipyretic and analgesic drug, and is also used to prepare o-ethoxybenzamide (i.e., analgesic) and other drugs. Orally administered LD50 to mice is 1.4g/kg.
