Description of key information

The vapor pressures of m- and p-diisopropylbenzene were calculated via the Cox equation established on the basis of experimentally derived and validated data. The extrapolation yielded values of 0.328 (p-diisopropylbenzene) and 0.524 hPa (m-diisopropylbenzene) at 25°C.The vapor pressure of p-diisopropylbenzene was calculated via the Antoine equation log P=A-B/(t+C) (A=6.11567; B=1662.007; C=194.209; temperature t in °C and P in kPa) established on experimentally derived and validated data. The extrapolation yielded a vapor pressure P=0.034 kPa (=0.34 hPa) at 25°C.
