Any other information on results incl. tables
cis 1,4-dichloro-2-butene:
At 69°C and pH 7.16 a half-life of 0.02 days was determined. With a hydrolysis rate constant of 9.1E-03 +/- 1.1 at pH 7 a half-life of 3.2 days at 25°C is calculated.
trans 1,4-dichloro-2-butene:
At 69°C and pH 9.90 a half-life of 0.02 days was determined. With a hydrolysis rate constant of 9.0E-03 +/- 0.5 at pH 7 a half-life of 3.2 days at 25°C is calculated
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.
