ABSTRACT:
Process for the dimerization of ACN to substantially linear C.sub.6 dimers using organic phosphinites or phosphonites as catalyst, in the presence of a proton-donating solvent and optionally a hydrocarbon co-solvent, the ACN and solvent(s) being dry and at least one of the solvents having a boiling point higher than ACN and being capable of rapid phase separation with respect to the dimeric products. Enables the unreacted ACN to be removed by distillation and the solvent(s) and product to be readily separated. Preferably the catalyst partitions in favor of the solvent phase.
