Additional information

Adsorption / desorption

No experimental data are available. However, the soil adsorption potential for 2,4,6 -triisopropyl-m-phenylene diisocyanate was predicted by the computer program KOCWIN v2.00 (EPIWIN software) by US-EPA (Chemservice S.A., 2011). A Koc value of 539300 L/kg (5.393 E+005 L/kg) was estimated by the Salbjic molecular connectivity (MCI) method, which is taken more seriously into account, due to the fact that it includes improved correction factors. The traditional method gives a value of 3639000 L/kg (3.639 E+006 L/kg).

Henry´s Law constant

This information is not mandatory for a registration under REACH Regulation (EC) 1907/2006 in a tonnage band of 100 - 1000 tons/year. However, the HLC is important to derivate the PNECs for the ecotoxicology chapter. It can be predicted with the help of HENRYWIN v3.20 (EPIWIN software) by US-EPA (Chemservice S.A., 2011). A constant of 7.49 Pa*m³/mol was predicted at 25 °C for the substance 2,4,6 -triisopropyl-m-phenylene diisocyanate.

Distribution modelling and other distribution data

According to REACH Regulation (EC) 1907/2006 this information is not mandatory for a registration of a chemical at a tonnage band of 100 - 1000 tons/year.
