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.

Adequacy of study:

weight of evidence

Study period:

no data

Reliability:

2 (reliable with restrictions)

Rationale for reliability incl. deficiencies:

data from handbook or collection of data

Principles of method if other than guideline:

GLP compliance:

no

Key result

Temp.:

25 °C

Vapour pressure:

0.01 mm Hg

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.

Conclusions:

The vapour pressure under the study conditions was reported to be 0.0098 mm Hg (= 0.013 hPa) at 25 °C.

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.
