Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.

The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

Description of key information

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

Isopropanol

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.
