Description of key information

The soil sorption coefficient Koc of p-diisopropylbenzene was estimated by EC HPLC method to be logKoc = 3.8.

Calculation using EPIWIN v3.20, PCKOCWIN v1.66 yielded a value of 4036 (log Koc=3.606).The calculation of Koc based on molecular connectivity indexes yielded a value of 4000 and indicates that a  sorption of diisopropylbenzene onto soil organic matter is to be expected.

Key value for chemical safety assessment

Koc at 20 °C:
