Any other information on results incl. tables
study report:
The substance sulfurylchloride is decomposed by the buffer solutions immediately.
OECD SIDS:
Sulfuryl chloride reacts with water within 5 minutes at 20 °C completely, forming sulfuric and hydrochloric acid, thus sulfuryl chloride itself indicates no hazard for the aquatic environment.
The hydrolysis products are strong mineral acids that dissociate readily in water to the hydrated protons and sulfate respectively chloride ions. This total ionization will imply also, that the acids, themselves, will not adsorb on particulate matters or surfaces and will not accumulate in living tissues.
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.
