Description of key information
In contact with water the substance might hydrolyse rapidly, if acidic conditions are given.
Key value for chemical safety assessment
Additional information
A GLP test according to OECd guideline 111 revealed, that the substance hydrolyses rapidly under acidic conditions at ph4 with half-lifes < 2h at 20°C while the half-life increase up to ca. 50h at the same temprtaure at pH7. At higher pH value pH9 no hydrolysis occured within 192 h of test duration. This reulst is supported by the findings of Salomaa et al. (1966).They investigated the protolytic cleavage of isobutyl vinyl ether especially under acidic conditions. As result it can be assumed, that the ether bond is split under acidic conditions to form isobutanole and acetaldehyde as degradation products which are themselves hydrolytically stable. Furthermore, both substances are not classified regarding the environment. As the acute tests on aquatic organisms were performed under slightly alkaline conditions and an analytical test item verification took place, these tests can be regarded as valid for assessment.
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.
