beta-oxo-gamma-butyrolactone - Introduction
Tetronic acid, also known as Tetronic acid, is an organic compound. The following is an introduction to its nature, use, preparation and safety information.
Nature:
Tetronic acid is a colorless to pale yellow solid. It can be dissolved in water and organic solvents, and has good thermal stability. The compound is relatively stable at room temperature, but may decompose under the action of high temperature, sunlight or oxidants.
Use:
Tetronic acid has a variety of application functions, common uses include:
1. As a crosslinking agent and plasticizer in synthetic polymer materials to improve the mechanical properties and thermal stability of polymers.
2. for the preparation of water-soluble polymer compounds, such as polyols and polyamides.
3. In the field of medicine and biomedicine, the compound can be used as a component of a drug sustained-release system.
4. can be used for the preparation of surfactants, degreasing agents and emulsifiers.
Preparation Method:
There are many methods for preparing Tetronic acid. The common method is to react chloroacetic acid and methanol to generate ethyl methoxyacetate, and then oxidize it to obtain Tetronic acid.
Safety Information:
Tetronic acid is generally safer when used and stored correctly, but the following matters still need to be paid attention:
1. avoid contact with strong oxidants, strong acids or strong bases to avoid dangerous reactions.
2. in the use of the need for proper ventilation, to avoid the inhalation of dust or steam.
3. If taken by mistake or inhaled by mistake, please seek medical attention immediately.
4. in storage, should be stored in a dry, cool place, away from fire and flammable substances.
In summary, Tetronic acid is a widely used organic compound with many uses, but it is necessary to pay attention to safe operation during use to avoid potential hazards.
