139481-28-0 - Introduction
Methyl ester C4, also known as methyl ether, is an organic compound. The following is a brief description of the nature, use, preparation and safety information of methyl ester C4:
1. nature:
Methyl ester C4 is a colorless liquid with a sweet taste and aroma. It has a low boiling point and flash point, volatile, and can be compatible with many organic solvents.
2. use:
Methyl C4 has a wide range of uses in industry, mainly including the following aspects:
-Manufacture of natural flavors and food flavors: Methyl ester C4 can be used as a solvent and diluent for synthetic flavors.
-Solvent: Because the methyl ester C4 has good solubility, it can be used as a solvent for the manufacturing process of paint, cleaning agent, ink and glue.
-chemical raw materials: methyl ester C4 is an important intermediate of many chemical reactions, which can be used to produce esters, ethers, acids and other compounds.
-Pharmaceutical manufacturing: Methyl ester C4 is used as an important raw material in the synthesis of certain drugs.
3. Preparation method:
The common method for preparing methyl ester C4 is through the esterification reaction of methanol and butanol (n-butanol or isobutanol). In the reaction, methanol reacts with butanol to produce methyl ester C4 and water, and common catalysts can promote the reaction.
4. Safety Information:
The use of methyl ester C4 requires attention to safety issues:
-Methyl ester C4 has flammable properties and avoids contact with open flames or high temperature substances.
-Avoid inhaling vapors of methyl ester C4 to avoid respiratory irritation and poisoning.
-Wear appropriate protective gloves and glasses when using methyl ester C4.
-Store away from fire and oxidant, and store in a well-ventilated place. In case of leakage, appropriate emergency measures and cleaning methods shall be taken promptly.
