Improvements introduced in the object of the main patent 235,014 granted on April 30, 1957 by: "A process for the production of xanthogenic acid of 21-hydroxy-pregnenos and-pregnadienes and their salts" consisting of the production of 21-xanthogenic acid Δ 1,4-pregnadiene-3,20-dione 11 β. 17 α 21-triol and its salts, characterized by the process of reacting said triol with an alkali-metal hydroxide, then adding carbon disulfide and liberating the xanthogenic acid thus obtained by the addition of a strong acid, after which, if it is desired to obtain the salt of the xanthogenic acid, the xanthogenic acid is neutralized with the base corresponding to the desired salt.
