Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Additional information
The vapour pressures of the Intermediate CHIMEXANE NV/10 were determined as 16 mbar at 20 °C (extrapolation) and 63.9 mbar at 70 °C.
The measured values for pressure P and temperature T, which were performed in a temperature range of 38.9-87.5°C, were used to calculate six pairs of log P and 1/T. These values were plotted and the vapour pressures of the test item were calculated from the linear regression of the curve.
The correlation coefficient r being -0.9963, the linear regression was considered good.
However, the data comes from a certificate of analysis with a few experimental details and the purity was not specified. Then, the study was considered as not assignable but it was used in a weight of evidence approach.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
