 Calibration

The pressure readings and the calculated volume for the reference and sample cells are shown in the following table:

Table 2

Determination	P1 (psig)	P2 (psig)	P3 (psig)	P4 (psig)	Reference Cell Volume (cm^3)	Sample Cell Volume (cm^3)
1	17.096	6.474	17.492	8.668	90.826	149.019
2	17.298	6.553	17.366	8.603	91.061	149.314
3	17.225	6.525	17.235	8.537	91.079	149.356

Mean reference cell volume :          90.989 cm³
Mean sample cell volume    :          149.230 cm³

As the reference cell volume and sample cell volume were within the defined tolerance (90.953 ± 1.0 cm³and 149.225 ± 1.0 cm³for the reference and sample cell volumes respectively) the gas comparison pycnometer was therefore considered acceptable for use.

Sample

Conclusions:

The density of Ethyl Maltol has been determined to be 1.39*10^3 kg/m3 at 19.5 ± 0.5 °C and a relative density of 1.39.

Executive summary:

The density of ethyl maltol has been determined to be 1.39*10^3 kg/m3 at 19.5 ± 0.5 °C and a relative density of 1.39 in a study designed to be compatible with EU Method A 3 and OECD TG 109.
