Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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.

Info from HSDB database (http://toxnet.nlm.nih.gov/cgi-bin/sis/htmlgen?HSDB):
ATMOSPHERIC FATE: According to a model of gas/particle partitioning of semivolatile organic compounds in the atmosphere (1), diethyl carbonate, which has a vapor pressure of 10.8 mm Hg at 25 deg C (2), is expected to exist solely as a vapor in the ambient atmosphere. Vapor-phase diethyl carbonate is degraded in the atmosphere by reaction with photochemically-produced hydroxyl radicals (SRC); the half-life for this reaction in air is estimated to be 5 days (SRC), calculated from its estimated rate constant of 3.3X10-12 cu cm/molecule-sec at 25 deg C (SRC) determined using a structure estimation method (3). Diethyl carbonate may also undergo direct photolysis in the environment since this compound contains a functional group that can absorb light greater than 290 nm (4).

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.
