Description of key information
Additional information
The phototransformation of butyl isocyanate was estimated by the means of AOPWIN program v1.91 assuming 24 h per day and an OH radical concentration of 0.5 E6 molcecules/cm³. A dissipation half life of 4 days was derived (Bayer Industry Services, 2004).
n-Butyl isocyanate is not stable in aqueous media rapidly hydrolysing under the formation of CO2 and the water soluble hydrolysis products n-butylamine and di-n-butylurea. At time 0 (6 min after preparation of test solution) n-butylisocyanate was decomposed completely. Therefore, the half-life of n-butylisocyanate in aqueous media is less than 6 min ( Bayer Industry Services 2005).
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.
