DL-2-Hydroxy-n-butyric acid sodium sal - Introduction
2-hydroxybutyric acid sodium salt is an organic compound with the chemical formula C4H7NaO3. The following is a description of its nature, use, preparation and safety information:
Nature:
-Appearance: 2-hydroxybutyric acid sodium salt is a colorless solid, common form is crystalline or powder.
-Thermal stability: It will decompose at high temperatures and lose water and carbon dioxide gas.
-Solubility: It can be dissolved in water and is alkaline in aqueous solution.
-Chemical reaction: 2-hydroxybutyric acid sodium salt can react with acid to generate the corresponding sodium salt, and participate in esterification or acylation reaction.
Use:
-Medical field: 2-hydroxybutyric acid sodium salt has the effect of reducing plasma cholesterol and triacylglycerol levels, and is used as a lipid-lowering drug component.
-Food industry: As a food acidulant, it can be used for the preparation of acidulants and flavorings.
-Cosmetics: It can be used as an emulsifier, skin care agent and regulator in cosmetics.
Method:
2-hydroxybutyric acid sodium salt is generally prepared by neutralizing hydroxybutyric acid. First, an appropriate amount of hydroxybutyric acid is dissolved in water, and then sodium hydroxide solution is gradually added until bubbles are no longer generated in the reaction solution. Finally, the product of 2-hydroxybutyric acid sodium salt is isolated by filtration or crystallization.
Safety Information:
2-hydroxybutyric acid sodium salt is relatively safe in general use, but the following matters still need to be paid attention:
-Very intense contact may cause skin irritation and redness.
-Inhalation of dust or solution may cause coughing, difficulty breathing and other respiratory complaints.
-Avoid contact with strong acids to avoid violent chemical reactions.
-Wear appropriate protective measures such as goggles, gloves and protective clothing during use.
-When storing and handling, it should follow the relevant safety procedures and store it separately from other chemicals.
