Any other information on results incl. tables

Results of the two determinations are reported in the following table:

 


 
    Measurement     Determination
 1  2
 Temperature (°C)  19.9 19.9 
 Mass of empty pycnometer (g)  31.4374 31.4374 
 Mass of the pycnometer filled with ultrapure water (g)  81.4828 81.4828 
 Mass of the pycnometer filled with the test item (g) 78.4053  78.4087 
 Density of the test item (kg/m3)  936.9  937.0
 Mean Density (kg/m3)     936.9

The two determinations are within the validity criteria of the method: (less than 1% of difference).

No additional determination was performed.  

Applicant's summary and conclusion

Conclusions:
The density of the test item of REACTION MASS OF TOLUENE AND 2-VINYL-1,3-DIOXOLANE has been determined to be 936.9 kg/m3 at 20.0 +/- 0.1°C (mean of two determinations).
The relative density of the test item was determined to be D 20/4 = 0.937
Executive summary:

A study was performed to determine the density of the test item REACTION MASS OF TOLUENE AND 2-VINYL-1,3-DIOXOLANE.

The method followed was designed to be compliant with the OECD Guideline for Testing of Chemicals No. 109, ''Density of Liquids and Solids'' (2012) and the Method A.3 of Commission Regulation No. 440/2008, ''Relative Density''.

In this method, the density is determined at a specific temperature using a pycnometer.

Density is calculated from the difference in weight between the full and the empty pycnometer and its volume. The pycnometer volume is determined by carrying out the experiment at the selected temperature with the quantity of ultrapure water required to fill the pycnometer.

Two trials were conducted.

The following results were obtained:

 
 Trial  Density (kg/m3) at 20.0 +/- 0.1°C
 1  936.9
 2  937.0
 Mean  936.9

These values respect validity criteria (less than 1% of difference). Moreover, the bath used to maintain the pycnometer at 20°C did not vary by more than 0.1°C.

The density of the test item was determined to be 936.9 kg/m3 at 20.0 +/- 0.1°C (mean value of two independant determinations).

The relative density of the test item was determined to be D204 = 0.937.
