Results and discussion
Any other information on results incl. tables
A determination of water solubility was not possible for the following reasons:
1. When preliminary tests were performed, disappearance of the 2 phases was observed on prolonged standing.
2. A reduction of the stirring time to 4 hours and immediate analysis of the content showed that 1,3-dichlorobut-2 -ene content decreased by 26% between the first and eighth injections.
3. In a subsequent main experiment using 10 times the originally weighed-in amount of test material, the mixture was homogeneous after half of the prescribed stirring time, which indicated hydrolysis and solubilization.
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.
