| titleOfInvention | A process for the manufacture of oils and paraffin wax |
| abstract | Oils such as lubricating or gas oil are dewaxed by adding a diluent and a pour point depressant and separating the wax at a low temperature. Pour point depressants consist of; cracking or distillation residues from oils, asphalt, polymerized aromatic compounds obtained from hydrocarbon oils, pyrogenetic polymerization or condensation products from vegetable oils or fats, metal soaps, or compounds built up of 5 and/or 6 atoms having side chains as described in Specification 419,820. Example: a lubricating oil is diluted with ethyl alcohol and benzine and a small amount of a cracking residue, aluminium stearate or di-stearyl picene is added. The mixture is then cooled to -20 DEG C., and filtered. Gasoline, acetone, butyl alcohol, tetrahydro-naphthalene, benzene, or mixtures thereof may also be used as diluents. The pour point depressant is usually separated with the wax. The dewaxed lubricating-oil may be further treated with a decolorizing earth. |
