Henry's Law constant was determined using a batch air stripping method. HLC values were measured for both of the (1-methylethyl)-1,1'-biphenyl isomers present in the test substance.
Test substance consisted of two
isomers of isopropylbiphenyl. For both isomers, HLC values could be
determined. Measurements were carried out under ambient conditions.
Henry's law constants of 3-isopropylbiphenyl and 4-isopropylbiphenyl
were 0.07 and 0.096 (dimensionless), respectively. Conversion resulted
in respective values of either 1.71 E-03 and 2.35 E-03 atm m³/mol or
173.3 and 238.1 Pa m³/mol. Result for 3-isopropylbiphenyl is taken as
key value as this isomer is the main component in the Applicant´s
product, isopropylbiphenyl (mixture of isomers).
