The composition of solid paraffin waxes produced from high-sulfur crudes
- 73 Downloads
White waxes from high-sulfur crudes, having a melting point of 50–62°C and obtained by selective solvents and adsorbent refining mainly (about 90%) consist of paraffinic hydrocarbons.
For an oil content of 1–1.5% in these waxes, the amount of cyclic hydrocarbons, principally naphthenes, is not less than 10%; the greater the deoiling of a wax, the lower is its content of cyclic hydrocarbons, particularly aromatics.
A more thorough study of the aromatic hydrocarbons contained in commercial waxes is an urgent problem for scientific research institutes.
