Introduction

Methyl propionate, also known as methoxyacetate. The following is an introduction to the properties, uses, preparation methods and safety information of methyl propionate:

 

Quality:

- Appearance: Methyl propionate is a colorless transparent liquid with a special fragrance.

- Solubility: Methyl propionate is more soluble in anhydrous alcohols and ether solvents, but less soluble in water.

 

Use:

- Industrial use: Methyl propionate is an important organic solvent that is widely used in coatings, inks, adhesives, detergents and other industries.

 

Method:

The preparation of methyl propionate is often esterified:

CH3OH + CH3COOH → CH3COOCH2CH3 + H2O

Among them, methanol and acetic acid react under the action of a catalyst to form methyl propionate.

 

Safety Information:

- Methyl propionate is a flammable liquid and should be kept away from open flames and high temperatures.

- Exposure to methyl propionate may cause eye and skin irritation, so precautions should be taken.

- Avoid inhaling the vapor of methyl propionate and should operate in a well-ventilated area.

- In case of accidental ingestion or inhalation, seek medical attention immediately.
