Introduction
Methyl butyrate. The following is an introduction to some of the properties, uses, preparation methods and safety information of methyl butyrate:
Quality:
- Methyl butyrate is a flammable liquid that is less water-soluble.
- It has good solubility, soluble in alcohols, ethers and some organic solvents.
Use:
- Methyl butyrate is commonly used as a solvent, plasticizer and diluent in coatings.
- It can also be used as an intermediate in organic synthesis for the preparation of other compounds.
Method:
- Methyl butyrate can be prepared by reacting butyric acid with methanol under acidic conditions. The reaction equation is as follows:
CH3COOH + CH3OH → CH3COOCH2CH2CH3 + H2O
- The reaction is often carried out by heating with a catalyst (e.g., sulfuric acid or ammonium sulfate).
Safety Information:
- Methyl butyrate is a flammable liquid that can burn when exposed to open flames, high temperatures, or organic oxidants.
- Contact with skin and eyes may cause irritation and burns, precautions should be taken.
- Methyl butyrate has a certain toxicity, so it should be avoided for inhalation and accidental ingestion, and used under well-ventilated conditions.
- Care should be taken to prevent contact with oxidants, acids and alkalis when using or storing.
