Introduction
Introduction
L-lactic acid is an organic acid. The following is an introduction to the properties, uses, production methods, and safety information of L-lactic acid:
Properties:
- L-lactic acid is a liquid that is soluble in water and many organic solvents.
- It is acidic and exhibits acidic reactions in water.
- L-lactic acid has a sweet taste.
- It is relatively stable at room temperature but decomposes at high temperatures (above 130°C) or under strong oxidizing conditions.
Uses:
- L-lactic acid can be used as a raw material for certain polymers, such as biodegradable plastics.
Production Methods:
- L-lactic acid can be produced through chemical synthesis or fermentation.
- Chemical synthesis generally uses ethylene as the raw material, undergoing esterification and hydrolysis reactions in the presence of a catalyst.
- Fermentation uses certain bacteria or fungi, such as lactic acid bacteria or red yeast, to convert starch or sugar into lactic acid.
Safety Information:
- In industrial applications, appropriate safety procedures should be followed, such as avoiding direct contact with the skin or eyes, and using protective gloves and goggles.
- People with allergies may experience discomfort; if an allergic reaction occurs, use should be stopped immediately and a doctor should be consulted.
