Applicant's summary and conclusion
- Conclusions:
- The freezing point of the test substance was determined to be -23 deg F (-31 deg C)
- Executive summary:
The freezing point of trimethyl borate was determined. As the test substance was cooled, the temperature was recorded every fifteen seconds over a timespan of 32.25 minutes. A temperature versus time plot was prepared for each replicate determination. The freezing point was determined from the equilibrium portion of the freezing curve. Following ASTM method D 101 5-99, the freezing point of trimethyl borate was determined to be -23 °F (-31°C).
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.
