Since TMQ is a mixture of oligomers of 1,2-Dihydro-2,2,4-trimethylquinoline, TMQ-dimer and TMQ-trimer were used as typical composition to estimate its henry's law constant with HENRYWIN v3.10. The estimated constant was in the range of 2.8*10-9 - 3.0*10-5 Pa*m3/mol (Currenta, 2010), which is much lower than 1 Pa*m3/mol; and hence TMQ is essentially non-volatile.
