Abstract: Disclosed is a method for preparing a dinitrile compound. The method includes reacting an alcohol compound with a nitrile compound having a terminal carbon-carbon unsaturated bond under anhydrous conditions. A potassium alkoxide having 1 to 5 carbon atoms is used as a catalyst in the course of the reaction. According to the method, a high-purity dinitrile compound can be prepared in a simple manner within a short reaction time indicating high productivity.

Abstract: An imporved process for producing tricyanoethylated pentaerythritol by selectively cyanoethylating only three hydroxy groups of pentaerythritol in a high yield such as 90 to 95%, involves reacting one mole of pentaerythritol with three mole of acrylonitrile by Micheal Addition Reaction in an alkaline aqueous solution in coexistence with an extraction solvent. The tricyanoethylated pentaerythritol has a high purity and is useful for production of a high dielectric polymer.

Abstract: The 3-(hexenyloxy)-propane-nitriles of general formula A, in which R.sup.1 and R.sup.2 are optionally a hydrogen atom or a methyl group and R.sup.3 is an unbranched hexenyl group, are new and are useful as odour materials such as ingredients for perfume compositions. Their production is carried out through the base catalysed addition of acrylonitrile or methyl substituted acrylonitrile to the unbranched hexenol, in which the reaction temperature is between 0.degree. and 50.degree. C. (for acrylonitrile especially between 0.degree. and 10.degree. C., for crotonitrile especially between 15.degree. and 25.degree. C. and for methacrylonitrile, especially between 30.degree. and 40.degree. C.), and the aforesaid base is benzyl trimethylammonium hydroxide (Triton B).

Abstract: The present invention relates to novel methods of stabilizing polymers of acrylonitrile. The polymers are stabilized by the inclusion of small amounts of stable free radicals compounds which act to inhibit the homopolymerization of the acrylonitrile while promoting the reaction of the acrylonitrile with nucleophilic species such as amines and alcohols.

Abstract: This invention relates to a process for the separation of acrylonitrile used in the cyanoethylation of glycols to produce a bis(cyanoethylated) aliphatic glycol from the resulting glycol which is then reduced with hydrogen to produce the corresponding bis(aminopropoxy) alkane. In this process, acrylonitrile or methacrylonitrile is reacted with an aliphatic glycol in stoichiometric excess and the acrylonitrile removed from the cyanoethylated glycol by reaction with aliphatic primary or secondary alcohol prior to effecting the hydrogenation of the cyanoethylated aliphatic glycol in the presence of the acrylonitrile-amine reaction product. The reaction product then can be separated by conventional techniques such as distillation.
