Glossary: Laboratory operations
- auto-ignition temperature. Compare with flash point.
- Minimum temperature at which the vapor/air mixture over a liquid spontaneously catches fire.
- autoxidation. autooxidation; autoxidize; autoxidizing.
- Oxidation caused by exposure to air. Rust is an example of autoxidation. Autoxidation makes ether taken from half-filled bottles very dangerous, because air oxidizes ether to highly explosive organic peroxides.
- Bunsen burner.
- A gas burner with adjustable air intake, commonly used in laboratories.
- flash point. Compare with auto-ignition temperature.
- The temperature when vapor pressure of a substance becomes high enough to allow the air/vapor layer over the substance to be ignited. Ether and acetone have flash points below room temperature, which makes them very dangerous.
- MSDS. material safety data sheet.
- Safety information sheet for a particular substance that lists physical properties, hazards, cleanup and disposal procedures, fire and explosion data, and protective equipment required.
- pyrophoric. pyrophoric solid.
- Catches fire spontaneously when exposed to air at normal room temperature. For example, powdered potassium metal is pyrophoric.
