| titleOfInvention | PROCESS FOR SEPARATING A MIXTURE OF CYANOACIDS HAVING AN EUTECTIC |
| abstract | The present invention relates to a particular method for separating a mixture of two linear cyano-acids resulting from the oxidative cleavage of an unsaturated fatty acid nitrile, said mixture having a eutectic of specific composition. Said method comprises steps of crystallization separation in several successive steps in the melt of the starting mixture and to bypass the eutectic during this crystallization a step is carried out for separating the components of the eutectic by distillation under reduced pressure and / or by selective extraction by specific solvent or by column chromatography and with the possibility of recycling the fractions thus obtained in the chain of successive crystallizations thus making it possible to obtain the separation of two components with a purity of at least 95 mol%. |
