Density:

950 kg/m³

Temp.:

20 °C

The density of a substance is the quotient of the mass and the volume of that substance at a specific temperature. The SI unit is kg/m³. 1 g/cm³ corresponds to 1000 kg/m³.

The density (ρ) of the test item was calculated based on the ratio of the mass of test item to the mass of water used to fill the pycnometer using the following equation:

Equation 1: ρ=d.(c-a)/(b-a)

where:

a = mass of pycnometer (g)

b = mass of pycnometer filled with water (g)

c = mass of pycnometer filled with test item (g)

d = density of water at test temperature (kg/m³)

The relative density of solids or liquids is the ratio between the mass of a volume of substance determined at 20 °C, and the mass of the same volume of water determined at 4 °C. Relative density has no dimensions. The density of water determined at 4 °C is 999.97 kg/m³ (as published by the CRC Handbook of Chemistry and Physics, 93rd Edition 2012-2013).

The relative density (D204) of the test item was calculated using the following equation:

Equation 2: D204 = ρ/999.97

where: ρ = density of the test item (kg/m³)

Conclusions:

The density of 4,8-Dimethyl-2,5,7,10-tetraoxaundecane has been determined to be 950 kg/m3 at 20.0 ± 0.5 °C and a relative density of 0.950.

Executive summary:

The density of 4,8-Dimethyl-2,5,7,10-tetraoxaundecane was carried out by the pycnometer method and was determined to be 950 kg/m3at 20.0 ± 0.5 °C and a relative density of 0.950.
