Additional information

The weight of evidence from authoritative secondary sources indicates that 1,4 -Butenediol has a vapour pressure of 0.00715 hPa (MpBpWIN 1.43 Estimate 2010) to 0.0087 hPa (Daubert et al. 1989) at 25 °C. Additional vapour pressure values for 1,4 -Butenediol from reliable sources and read-accross methods include 0.0616hPa at 25 °C (Japan CHRIP Database), 2.1 hPa at 99 °C (BASF AG 1969), 1.5hPa at 60 °C (GESTIS 2010), and 0.1 hPa at 44 °C (Read across - CRC 2010).
