Additional information

Stull (1947) reported a series of measured vapour pressure values from the literature (1895) in the temperature range between 134 °C and 262 °C. The original text is not available, so as the method description. The document is not considered reliable.

A recent guideline study was conducted by Halarnakar according to OECD Guideline 104, and Method A.4 (EC) No 440/2008. In accordance with Regulation (EC) No. 1907/2006, Article 13(3), the vapour pressure value 0.631 at 25 °C is carried forward for the purpose of risk assessment, classification and labelling.
