ABSTRACT:
In the recovery of N,N-dimethylaminoacetonitrile from a mixture thereof with water by extraction with an organic solvent thereby to form an aqueous phase and an organic solvent phase containing the nitrile, separating the organic phase, and recovering the nitrile from the organic solvent, the improvement which comprises employing 1,2-dichlorobenzene as the organic solvent. Recovery of the nitrile from the organic solvent can be accomplished by distilling of the nitrile, the undistilled solvent being recycled for further use.
