Density:
The density of test item N-benzyl-N-ethylaniline (CAS No. 92-59-1)was determined following OECD Guideline 109 and according to the IS 4730 : 1994 (Reaffirmed 2010) – Method for Determination of Density of Liquids (First Revision) using glass pyknometer .The mean of test item was determined to be 1.0239 g/cm³at 20 °C and 965.3 hPa .
Particle size distribution:
the study does not need to be conducted because the substance is marketed or used in a non solid or granular form (Test material N-Benzyl-N-ethylaniline is Physically appear in the liquid form.)
Vapour pressure:
Vapour pressure of N-Benzyl-N-ethylaniline is determined to be 0.013 Pa, 0.39 Pa & 1.06 Pa at 20, 50, & 60 Deg C respectively.
Partition coefficient:
