Applicant's summary and conclusion
- Conclusions:
- The determination of the flash point was performed with n-Butyllithium 90% in hexane according to DIN EN ISO 17736. Based on this a preliminary flashpoint of lower than - 13.9 degree C was found. No reliable results were obtained with a standard OECD test. But the handling caused a risk to the laboratory staff.
- Executive summary:
The determination of the flash point was performed with n-Butyllithium 90% in hexane according to DIN EN ISO 17736. Based on this a preliminary flashpoint of lower than - 13.9 degree C was found. However, after the substance was poured out of the cup, self ignition occurred and the flame was extinguished by means of nitrogen. The remaining sample amount was diluted with n-heptane to a concentration of about 5 to 10 %. No further experiments were performed due to risk in handling the substance. Again, no reliable results were obtained with a standard OECD test. But the handling caused a risk to the laboratory staff.
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.
