Abstract
A transformer oil processing sequence is disclosed which produces a superior oil without the use of large doses of sulfuric acid and the resultant sludge problems. The process comprises contacting a naphthenic based oil with an oxygen-containing gas in the presence of a catalytic amount of sulfuric acid under mild conditions of temperature and pressure and caustic washing the resultant product. The caustic washed product is then hydrogenated.
