    Abstract: Certain organic reactants which are free from aliphatic unsaturation and which are capable of yielding free radicals upon treatment with peroxides are oxidized, in the liquid phase in an aqueous medium, with certain peroxy compounds to form freeradical intermediates which are then allowed to react further with themselves or with other components of the reaction medium to form useful end products. Preferred features include the slow addition of the peroxy compound to the reaction zone and the use of certain metalic ions to improve yields. The process may be used for the reaction of HCN and carboxylic acids to produce nitriles; the conversion of tertiary alkanols to ketones; and the production of cyanogen from hydrogen cyanide.

    Abstract: Pure acetonitrile is recovered from aqueous acetonitrile by extracting with an organic solvent which has little miscibility with water, boils higher than acetonitrile and does not form an azeotrope with acetonitrile. The portion of the extract boiling up to 76*C is distilled off. The remaining acetonitrile containing more difficulty volatile portion is freed from the residual water by addition of an entraining agent and recovering the pure acetonitrile by a fractional distillation.

    Abstract: A PROCESS IS PROPOSED FOR THE PREPARATION OF A REACTION PRODUCT CONTAINING AT LEAST ONE COMPOUND SELECTED FROM AN ALKYL NITRILE, A FATTY ACID AND A FATTY ACID AMIDE. THE PROCESS COMPRISES REACTING A 1-NITRO-2-NITROSOALKANE, SUCH AS 1-NITRO-2-NITROSOHEXANE, OR A 1-NITROALKANONE-2 OXIME, SUCH AS 1-NITROHEXANONE-2 OXIME, WITH AQUEOUS SULFURIC ACID IN WHICH THE CONCENTRATION OF THE H2SO4 IS SUFFICIENT TO FORM A ONE PHASE REACTION MEDIUM WITH THE 1-NITRO CONTAINING CHARGE STOCK AND, OPTIONALLY, IN THE PRESENCE OF A LOWER ALKYL FATTY ACID, SUCH AS ACETIC ACID, AS A DILUENT. PHOSPHORIC ACID IN THE SAME CONCENTRATION RANGE CAN BE SUBSTITUTED FOR THE SULFURIC ACID TO PRODUCE A REACTION PRODUCT CONTAINING AT LEAST ONE COMPOUND SELECTED FROM A FATTY ACID AND A FATTY ACID AMIDE.
