Measured values for Formaldehyde, and where each one comes from
38 measured values for 13 properties, read from 4 public databases. On 5 properties the records differ. Each reading is shown with its own record. Follow any record to read the value at its source.
Boiling point
6 records, -21 to 101 °C
Used with vapour pressure to judge how readily the substance reaches the air you breathe.
- Boiling point: - 19.1 °C /Formaldehyde 37% uninhibited/
- Hazardous Substances Data Bank (HSDB)
- -6 °F
- NIOSH Pocket Guide
- -19.1 °C @760 [mm Hg]
- PAC Chemical Database, U.S. Department of Energy
Melting point
4 records agree
Fixes the physical state at handling temperature, which the label and the transport class depend on.
- -134 °F
- NIOSH Pocket Guide
Flash point
5 records, -96 to 85 °C
The lowest temperature at which the liquid gives off enough vapour to ignite. It decides the GHS flammable liquid category.
