Solubility: miscible with water, and miscible in alcohols, esters, ketones, hydrocarbons, oils, etc.
Third, chemical properties
Stability: stable, non-polymerisation, but should avoid contact with strong oxidising agents, acids and alkalis.
Toxicity: relatively low toxicity, but still need to avoid direct contact with skin and eyes.
Fourth, the main use
Food industry: used as spice and flavouring agent, because it has good food compatibility and harmlessness.
Coatings and inks: used as environmentally friendly solvents in coatings, inks, detergents and adhesives due to their low volatility and environmental friendliness.
Pharmaceutical industry: used as an intermediate in the preparation of certain drugs due to its biocompatibility and low toxicity
Cosmetic industry: as a mild solvent and skin conditioner, it is widely used in skin care and cosmetic products.
Pesticide industry: used as solvents or auxiliaries for pesticides, to improve the dispersion and permeability of pharmaceuticals, and improve the effect of drug application.
V. Synthesis method
Esterification reaction: Lactic acid and ethanol are esterified in the presence of a catalyst (e.g. concentrated sulfuric acid) to produce ethyl lactate and water. The reaction is usually carried out under heating conditions to improve the yield.
Microbial fermentation: Using a carbon source such as glucose, lactic acid is fermented to produce lactic acid, which is then esterified to obtain ethyl lactate. This method is relatively environmentally friendly and sustainable.
