In one aspect, disclosed herein is an apparatus for determining the congealing point of a wax-containing sample, such as a petroleum wax-containing sample, the sample placed within a sample flask, comprising: Power is supplied to apparatus 10 across nodes Plants, animals and even insects produce materials sold in commerce as wax.

The fraction 10 is fed to a hydrogenation reactor 8 wherein fraction 10 is converted to a hydrogenated fraction 90 comprising 10 to 17 carbon atoms. Historical Version s – view previous versions of standard. Waxes are organic substances that tend to be solid at ambient temperature and become free-flowing at elevated temperatures.

Petroleum wax producers also characterize wax by degree of refinement; fully refined paraffin has oil content generally less than 0. Suitably, the first light wax fraction is obtained as top cut of the vacuum distillation, the second light wax fraction is obtained as a side cut of the vacuum distillation and the third light wax fraction is obtained as heavier side cut of the vacuum distillation.

Also the distillation is. Please first verify your email before subscribing to alerts.
