       Gasol from the Fischer-Tropsch synthesis, converted into various chloroderivatives, is easily caused to react with aromatic hydrocarbons and an AlCl₃ catalyst to produce synthetic lubricants fluid at low temperatures, is very resistant to oxidation, but also susceptible to temperature changes.  3 methods are described for improving the product.  The conclusions are that satisfactory high-grade lubricants may be made by gasification of any solid fuel by way of Kogasin synthesis without rejecting any fractions as unsuitable.  Products of these improved processes show stability against oxidation, C residue, and pour point and compare favorably with the products of crude petroleum.
