Description of key information
Additional information
According to the classification scheme of Swann et al. (1983), TMQ has a high adsorption potential in soil/sludge with the adsorption coefficient (log Koc) mostly above 4.09. TMQ is essentially non-volatile with the estimated Henry's law constant in the range of 2.8*10-9 to 3.0*10-5 Pa*m3/mol at ambient temperature using TMQ-dimer and trimer as typical compositions. As a mixture of oligomer derivatives of 1,2-Dihydro-2,2,4-trimethylquinoline with diverse physico-chemical properties, generic distribution is hardly to be modeled. However, considering the low water solubility observed (<3.2 mg/l at 25°C and pH 9), the low vapour pressure (<< 1 Pa), and relatively high Log Pow (5.8 in average) and Log Koc (mostly above 4.09), the TMQ released into environment is expected to be mostly found in sediment and soil compartment.
