The mixture is clarified by lime and distilled, the fraction boiling from 100--150 DEG  C. being mixed with coal tar, lime, benzine, turpentine and methylated spirits; (2) An initial tar distillate is mixed with a paste of coal tar, lime, and soda, the mixture is heated and strained. p-Dichlorbenzene, sulphuric acid, dilute phosphoric acid and methylated spirit are added, the liquid clarified by wood ash and heated.  A paste of coal tar, lime and soda is added, the liquid strained, and diluted with paraffin; (3) Rosin is melted and turpentine and methylated spirits added, with or without p-dichlorbenzene.  To this third mixture, while hot, are added equal quantities of (1) and (2) the whole forming the black oil whether separated or not from the lower watery layer.  This may be diluted with benzole, dichlorethylene, fusel oil, methylated spirits, and petrol, distilled over lime at 100 DEG  C., clarified by acetone and benzole, and mixed with petrol, acetone, fusel oil, and dichlorethylene to form a petrol substitute.  Alternatively, the black oil may be diluted with turpentine, dichlorethylene, ether and benzine to produce a "base liquid" suitable for lighting purposes. This base liquid may be mixed with linseed or similar oils to form a lubricant.  Fuels suitable for internal-combustion engines may be prepared from the base liquid by diluting with petrol or with petrol, dichlorethylene, ether, and benzine.  Before use such oils should be clarified by lime and lead acetate, and oxidized. Another light oil may be obtained by adding to the base liquid, benzine, petrol, and a mixture prepared as follows: Liquor from waste citrous fruit peels is mixed with dichlorethylene and sulphuric acid and allowed to stand. There are then added benzine, ether, turpentine, fusel oil, and acetone, the mixture is clarified by lime, and strained.
