Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.
The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

| 1 | 122-79-2 | Phenyl acetate | biodegredation | [Urano K, Kato Z; J Hazard Materials 13: 147-59 (1986)] | 13% of the theoretical BOD was reached in 30 hours with a lag period ranging from 0 to 5 hours; a first-order rate constant of 0.060/hr was calculated from this process. | ||
| 2 | 122-79-2 | Phenyl acetate | abiotic degredation | [(1) Meylan WM, Howard PH; Chemosphere 26: 2293-99 (1993) (2) Marsh MR et al; J Chem Research 8: 248-9(1989)] | The rate constant for the vapor-phase reaction of phenyl acetate with photochemically-produced hydroxyl radicals has been estimated as 2.05X10-12 cu cm/molecule-sec at 25 deg C(SRC) using a structure estimation method (1,SRC).This corresponds to an atmospheric half-life of about 8 days at an atmospheric concn of 5X10+5 hydroxyl radicals per cu cm (1,SRC).A base-catalyzed second-order hydrolysis rate constant of 1.3 L/mol-sec (2) was measured at 25 deg C; this corresponds to half-lives of 61 and 6 days at pH values of 7and 8, respectively (2,SRC). | ||
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.
