The phototransformation in air of
2,4,6-triisopropyl-m-phenylene diisocyanate was predicted with the help
of the computer program AOPWIN v1.92 (EPIWIN software) by US-EPA ,
resulting in an atmospheric half-life of 0.280 days (around 3.40 hours)
(Chemservice S.A., 2011).
Regarding hydrolysis, one experimental
result as well as one QSAR prediction is available for the test
substance. Based on the results of the experimental study, the test
substance is hydrolytically unstable and undergoes rapid hydrolysis.
Abiotic degradation > 90% was observed within 3 min at 20 °C in
demineralized water with a half life time of about 37 seconds (Neuland,
2020). This result is supported by the prediction of HYDROWIN v2.00
(EPIWIN software) by US-EPA, which detected ISOCYANATES as hydrolysable
substance class (Chemservice S.A., 2012). Accordingly, the
hydrolysis half-life will be less than 10 minutes at 25 °C and even at
