Abstrakt:

Simple methods and apparatus for determination of the density of liquids at variable temperatures were developed. Their correct function was demonstrated by the comparison of the literature and experimental data for ethanol. The temperature dependences of the density of crude rape seed oil and of rape seed oil-ethyl ester (bio-diesel) were measured in the interval of 15–70 °C. The precision of the method described is better than ± 0.5 mg cm−3 at the temperature tolerance ± 0.1 °C.
