Description of key information

Reaction mass of ethanol and isopropanol:
Company owned data; determination according to standard methods
Two separate TGD-approved handbooks agree that the substance has a melting point of about -89°C. No information on the atmospheric pressure reported.
-114 degrees C

Key value for chemical safety assessment

Melting / freezing point at 101 325 Pa:
-122 °C

Additional information

The melting point of the reaction mass is determined to be -122 degrees C according to standard methods (company owned data). This is comparable to the melting point values of the two constituents.


Information concerning melting/freezing point of IPA was sourced from two separate handbooks. Merck Index: An Encyclopedia of Chemicals, Drugs, and Biologicals (14th Edition) and CRC Handbook of Chemistry and Physics (81st Ed), which are known to contain peer-reviewed data of Klimisch-2 reliability state that the substance has a melting point of -88.5°C (corresponding to 184.65 K), and -89.5°C (corresponding to 183.65 K), respectively.
