Measured values for Diethyl ether, and where each one comes from

33 measured values for 12 properties, read from 4 public databases. On 4 properties the records differ. Each reading is shown with its own record. Follow any record to read the value at its source.

Boiling point

4 records, 34 to 35 °C

Used with vapour pressure to judge how readily the substance reaches the air you breathe.

34.6 °C at 760 mm Hg; 17.9 °C at 400 mm Hg; 2.2 °C at 200 mm Hg: Hazardous Substances Data Bank (HSDB)
94 °F: NIOSH Pocket Guide
94 °F: OSHA Occupational Chemical Database
34.5 °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.

-116.3 °C (stable crystals); -123.3 °C (metastable crystals): Hazardous Substances Data Bank (HSDB)

Partition coefficient (log Kow)

1 record

Indicates whether the substance accumulates in fat or in water, which drives the environmental sections.

log Kow= 0.89: Hazardous Substances Data Bank (HSDB)

Viscosity

1 record

Governs how far a spill spreads and how fast it soaks into a surface or a sorbent.

0.2448 centipoise at 20 °C: Hazardous Substances Data Bank (HSDB)

Odour

2 records, each a different case

Odour is a warning property only. Many substances are hazardous well below the concentration you can smell.

Sweetish, pungent odor: Hazardous Substances Data Bank (HSDB)
Ethereal odor: Hazardous Substances Data Bank (HSDB)

These are the public records read for Diethyl ether, published here unchanged. Where two records disagree, the draft you buy states the value and names the record behind it, so a reviewer can see what was chosen. Every draft needs review by a competent person before it is issued.
