Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

>= 96.8 - <= 103.2 °C
Atm. press.:
ca. 1 013 hPa
Decomposition:
no

Any other information on results incl. tables

The limits of the melting range are the respective mean values from two measurements as given below:

Test #

Start of Melt (°C)

End of Melt (°C)

97.2

103.6

2

96.3

102.7

The solid melted without decomposition. The range is relatively broad, because it is a composition of C4 to C11 fatty acids.
