Abstract
Drying-oils are obtained by treating a liquid product of vapour-phase cracking, having considerable di-alkene content, with a small quantity such as 1 per cent or less of aluminium chloride or like halogenide at a moderate temperature preferably not above 70 DEG C., for instance at room temperature. The reaction product usually forms two layers, the majority of the drying oil being in the upper layer. The upper layer, if desired after treatment with dilute acid, dilute lye, or water, is concentrated by distillation, which may be under reduced pressure until a product of the desired concentration is obtained. This concentration may be carried far enough to produce a very viscous oil, which can be brought to a desired degree of fluidity by dilution with a solvent. In an example the raw material is treated with 1 per cent of aluminium chloride at room temperature for 5 hours with stirring. The upper layer is washed with dilute hydrochloric acid and then with water and distilled at normal pressure until constituents boiling up to 220 DEG C. have been removed. The lower layer or sludge, after treatment with dilute hydrochloric acid and water, and vacuum distillation also yields a residue of drying oil. The drying oil is suitable for the manufacture of lacquers either alone or together with natural drying oils. The drying proceeds in a similar manner, decrease of weight first occurring owing to the evaporation of the lacquer solvent, and then increase of weight owing to oxidation.ALSO:Drying-oils are obtained by treating a liquid product of vapour-phase cracking, having considerable di-alkene content with a small quantity, such as 1 per cent or less, of aluminium chloride or like halogenide at a moderate temperature, preferably not above 70 DEG C., for instance at room temperature.
