Lactic acid ester - Names and Identifiers
Lactic acid ester - Introduction
Lactic acid ester is a kind of esterification product with Lactic acid as acid group. Its chemical formula is C3H6O3, and its structure contains a carboxylic acid group and one or more alcohol groups. Lactic acid ester has the following properties:
1. Physical properties: Lactic acid ester is a colorless to pale yellow liquid, with a unique sweet and sour taste and special acid alcohol flavor. It can be used as solvent, catalyst and additive.
2. Chemical properties: Lactic acid ester has good stability and solubility, and can be hydrolyzed into Lactic acid and corresponding alcohol under certain conditions. Lactic acid ester is widely used in esterification reactions, and can synthesize esters with different carbon chain lengths and functional groups.
Lactic acid ester has many uses in industry and daily life:
1. Food and pharmaceutical industry: Lactic acid ester is an important ingredient in food and pharmaceutical additives. It is used as a flavoring agent, an acidulant and a preservative in food and beverages, and is also used in the manufacture of lactate.
2. Cosmetics and personal care products: Lactic acid ester is often used as an emulsifier, stabilizer and moisturizer in cosmetics and personal care products to improve the texture and stability of products.
3. Industrial application: Lactic acid ester is also widely used in the synthesis and modification of plastics, coatings, inks, dyes and other industrial products.
Lactic acid ester is generally obtained by esterification. The reactant Lactic acid can be heated to react with the corresponding alcohol under acidic conditions to produce Lactic acid ester and water. Catalysts such as sulfuric acid, zinc chloride, and the like may also be used to facilitate the reaction.
Regarding the safety information of Lactic acid ester, Lactic acid ester is generally considered to be a relatively safe compound, but the following matters still need to be paid attention:
1. Use should follow the relevant operating safety regulations, such as wearing appropriate protective equipment and ensuring good ventilation conditions.
2. Avoid reaction with strong oxidants, strong acids and alkalis, so as not to cause danger.
3. Keep the container intact during storage and handling, away from fire and high temperature.
