    • A process is disclosed for the separation of 4-androsten-3,17-dione/1,4-androstadien-3,17-dione mixtures, which are produced, e.g., upon microbiological sterol-side chain decomposition, through conversion of said mixture into a mixture of 17.beta.-cyano-17.alpha.-hydroxy-4-androsten-3-one/17.beta.-cyano-17.alpha.-hydroxy-1,4-androstadien-3-one, from which the difficultly soluble 17.beta.-cyano-17.alpha.-hydroxy-4-androsten-3-one is separated in crystalline form through filtration, and the 17.beta.-cyano-17.alpha.-hydroxy-1,4-androstadiene remaining in the mother liquor is re-split, directly or after extraction with organic solvent, by treatment in alkaline medium, into 1,4-androstadien-3,17-dione, and isolated as such. The separation of the products follows in high yields, and in sufficient purity for further working-up in the synthesis of androstane and pregnane derivatives, as well as estratrienes.

    • DL pantolactone is made by(a) introducing isobutyraldehyde, formalin and sodium cyanide solution continuously at a predetermined rate into a circulation reactor, continuously circulating the said mixture in said reactor while cooling the circulating mass in a heat exchanger, thus continuously causing the heat generated in the reaction between the components of said mixture to be discharged in said heat exchanger and by continuously re-mixing the formed reaction product with the reaction components;(b) continuously passing part of the reaction product into an after-treatment reactor where the said reaction is completed without re-mixing so as to form formisobutyraldolcyanohydrin;(c) passing the latter product into a first reaction chamber, reacting therein the product with a continuously introduced non-oxidizing strong acid at an elevated temperature and pressure so as to hydrolyze the product, thus forming a solution of .alpha.,.gamma.-dihydroxy-.beta.,.beta.-dimethylbutyric acid;(d) passing the said solution to a second reaction chamber and maintaining the solution therein at said elevated temperature and pressure until the .alpha.,.gamma.-dihydroxy-.beta.,.beta.-dimethylbutyric acid is lactonized to DL-.alpha.-hydroxy-.beta.,.beta.-dimethyl-.gamma.-butyrolactone and finally(e) recovering the latter product from the acid solution.The process permits obtaining DL-pantolactone in a continuous operation at a high yield.
