- The EPI (Estimation Programs Interface) Suite¿ is a Windows®-based suite of physical/chemical property and environmental fate estimation programs developed by the EPA's Office of Pollution Prevention Toxics and Syracuse Research Corporation (SRC). EPI Suite uses a single input to run the following estimation programs: KOWWIN, AOPWIN, HENRYWIN, MPBPWIN, BIOWIN, BioHCwin, KOCWIN, WSKOWWIN, WATERNT, BCFBAF, HYDROWIN, KOAWIN and AEROWIN, and the fate models WVOLWIN, STPWIN and LEV3EPI. ECOSAR, which estimates ecotoxicity, is also included in EPI Suite.

Referenceopen allclose all
The above value was obtained from the HSDB on TOXnet where reference is made to Howard PH, Meylan WM; Handbook of Physical Properties of Organic Chemicals. Boca Raton, FL: Lewis Publ, 1997, as primary source. The primary source however was not checked as the data from TOXnet was peer-reviewed and assumed to be reliable.
Description of key information
Weight of evidence approach based on three peer-reviewed values from handbooks (1 Pa and 21 Pa both at 20 °C and 1.3 Pa at 25 °C), and two estimated values using calculation methods (US EPA EPI Suite software: 2.9 Pa at 25 °C; unspecified software: 1.3 Pa at 25 °C), were used to indicate the vapour pressure of ethylene carbonate.
Key value for chemical safety assessment
- Vapour pressure:
- 1 Pa
- at the temperature of:
- 20 °C
Additional information
The available vapour pressure values are in a close range, except for one value indicating 21 Pa at 20 °C. Therefore a rounded up value, excluding the outlier, is proposed as 1 Pa at 20 °C.
