First, the apparatus was tested by determination of the density of air and water at 20.0 °C. The results for water are given inTable 1. These values are in the accepted range of 0.9982 ± 0.0003 g/cm³.

 

Table 2shows the individual measurements for the density of Oxirane, mono[(C12-14-alkyloxy)methyl] derivs. / ERC Nr 17. From these, the mean value was calculated, corrected and given in the same table. The tabulated values represent rounded results obtained from calculation using the exact raw data. The relative density of Oxirane, mono[(C12-14-alkyloxy)methyl] derivs. / ERC Nr 17 was determined to be  D₄²⁰=0.8937.

Table 1       Results of the Calibration Using Air and Water

Test No.	Temperature [°C]	Density of water [g/cm3]
		measured	mean value	theoretical value
1	20.0	0.9982
2	20.0	0.9982	0.9982	0.9982
3	20.0	0.9982

 

The density of air was measured to be 0.0012 g/cm³.

Test No.	Temperature [°C]	Density of Oxirane, mono[(C12-14-alkyloxy)methyl] derivs. / ERC Nr 17 [g/cm3]
		measured	mean value	corrected for relative density
1	20.0	0.8937	0.8937	0.8937
2	20.0	0.8937

 

 

Calculation of the relative density

 

D₄²⁰ = 0.8937g/cm³/ 0.99997 g/cm³=0.8937

 

Conclusions:

The relative density of Oxirane, mono[(C12-14-alkyloxy)methyl] derivs. / ERC Nr 17 was determined to be 0.8937.

Executive summary:

The relative density of Oxirane, mono[(C12-14-alkyloxy)methyl] derivs. / ERC Nr 17 was determined to be

 

 

 D₄²⁰ = 0.8937

 

Description of key information

The determination of the relative density of the test item was performed in accordance with the EEC directive 92/69, EEC Publication No. L383, December 1992 and Council Regulation EC No. 440/2008, Methods for the determination of physico-chemical properties, A,3 "Relative density", as well as the OECD Guideline for Testing of Chemicals, No. 109, "Density of Liquids and Solids" using an oscillating densitimeter. As the density of the test item was determined at 20.0 °c, the relative density is stated.
The relative density of Oxirane, mono[(C12-14-alkyloxy)methyl] derivs. I ERe Nr 17 was determined to be 0.8937 at 20.0 °C.
