Executive summary:

The vapour pressure of Hydrocarbons,C5-C7 n-alkanes, iso alkanes,n-hexane rich is 18.5kPa at 20°C. The study followed a standard guideline and so is considered reliable for assessment.

Description of key information

There is vapour pressure data available for Hydrocarbons, C5 -C7, n-alkanes, isoalkanes, n-hexane rich. Additionally, data is available for Hydrocarbons, C6, n-alkanes, isoalkanes, cyclics, n-hexane rich and n-hexane and is presented based on analogue read across.

The vapour pressure is 18.5 kPa for Hydrocarbons, C5-C7, n-alkanes, isoalkanes, n-hexane rich at 20°C, according to testing methodology EEC A4.
