Introduction
Methyl 2-methylbutyrate. The following is an introduction to its nature, use, manufacturing methods and safety information:
Quality:
- Appearance: Methyl 2-methylbutyrate is a colorless liquid with a pungent odor.
- Solubility: Methyl 2-methylbutyrate is soluble in alcohols and ethers, but insoluble in water.
Use:
- Industrial uses: Methyl 2-methylbutyrate is often used as a solvent in the manufacture of plastics, resins, coatings, etc.
- Chemical laboratory uses: It is also commonly used as a reagent in organic synthesis reactions.
Method:
The preparation of methyl 2-methylbutyrate is usually accomplished by acid-catalyzed esterification reaction. Specifically, ethanol is reacted with isobutyric acid, and under appropriate reaction conditions, such as the addition of a sulfuric acid catalyst and temperature control, the reaction yields methyl 2-methylbutyrate.
Safety Information:
- Methyl 2-methylbutyrate is a flammable liquid that can produce toxic gases at high temperatures.
- Care should be taken to avoid contact with strong oxidizing agents when using or storing.
- Contact with the skin may cause irritation and allergic reactions, protective gloves, goggles and protective clothing should be worn during handling.
- If methyl 2-methylbutyrate is inhaled or ingested, move to a ventilated area immediately and seek medical attention as soon as possible.
