Methyl formate - Introduction
Methyl form, chemical formula HCOOCH3, also known as Methyl form, is an organic compound. The following is an introduction to the nature, use, formulation and safety information of Methyl form:
Nature:
-Appearance: colorless liquid
-Odor: pungent odor
-Density: 0.98g/cm³
-Boiling point: 54-56 ℃
-Melting point:-98 ℃
-Solubility: Soluble in ethanol and ether, slightly soluble in water
Use:
-Industrial use: Methyl form can be used as an intermediate for chemicals such as solvents, synthetic dyes and fragrances.
-Medical use: In the pharmaceutical industry, Methyl form can be used to synthesize certain drugs.
Preparation Method:
Methyl form is usually prepared by the reaction of formic acid and methanol. The reaction conditions are generally carried out in the presence of an acidic catalyst (such as sulfuric acid). The reaction equation is: HCOOH CH3OH -> HCOOCH3 H2O.
Safety Information:
- Methyl form has a pungent odor. Contact with skin and eyes may cause irritation and burns. Direct contact should be avoided.
-Long-term or heavy exposure to Methyl form may cause health hazards, including damage to the respiratory system, liver, and kidneys.
-When using Methyl form, care should be taken to control its volatilization and avoid inhaling its vapor.
-It must be used in a well-ventilated area and wear appropriate protective equipment, such as chemical protective gloves and goggles.
