Abstract
Acid tar oils or the tar acids extracted therefrom are refined so as to yield white not pink emulsions with water, by adding alkali and passing in gas containing oxygen. For example, to oil from which the more volatile portions have been removed for use as fuel there is added an aqueous solution containing 0,1 of the sodium hydrate necessary for neutralization, and air is blown in until oxidation of the constituents producing the pink colour is complete; the oil is then acidified to liberate the combined tar acids, or is allowed to settle and removed from the phenolate layer which is treated separately; dead oil may then be added in any desired quantity. Tar acids are preferably obtained by removing all the phenols by the theoretical quantity of sodium hydrate solution, and treating the extract with air at atmospheric temperature or while steam is blown in to remove entrained hydrocarbons and pyridine; the phenolate is then acidified. A disinfectant may be produced by mixing 20 grams of oil, 6,8 cc. of rosin, and 4 cc. of an aqueous solution containing 200 grams of sodium hydrate per litre.ALSO:Acid tar oils or the tar acids extracted therefrom are refined so as to yield white not pink emulsions with water, by adding alkali and passing in gas containing oxygen.
