Any other information on results incl. tables
From the measured data points of the vapour pressure curve the constants A and B of the Antoine equation
log10 p [Pa] = A + (B/T)
can be derived by regression of the data points to
A = 7.1377
B = -3237.95
Calculated vapour pressure values for 20, 25 and 50 °C

50 1.3 ×10-3
Applicant's summary and conclusion
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.
