Various raw materials are: Lignite coking oil (b. 200°-350°), definite fractions of cracked gas oil (b. 200°-325°) with 70-75% olefins of natural origin or synthesized by hydrogenation of CO. Production of these synthetic raw materials and oxidation of the products are discussed. The fatty acids produced are neutralized at 250°-300° with amines or alkaline earths. The soaps are odorless and contain no unsaponifiable matter. 4 practical methods of producing these soaps are described.
