The invention relates to a continuous method for separating a C4 cut (C4) by means of extractive distillation using a selective solvent (LM) in an extractive distillation column (EDK).

If the pan uses 11 bolts, the transmission is a C4 or a C5.

Origin, characteristics and valuation of the cut C4: origin and state of availability of the cut, average composition, specifications of the butadiene 1-3 produced.

The main differences between the selective hydrogenation of the C4 cut and those of the C2 and C3 cuts.

The invention relates to a continuous method for separating a C4 cut (C4) by means of extractive distillation using a selective solvent (LM) in an extractive distillation column (EDK).

The invention also relates to the agriculturally suitable salts of said compounds.

If the pan uses 11 bolts, the transmission is a C4 or a C5.

Origin, characteristics and valuation of the cut C4: origin and state of availability of the cut, average composition, specifications of the butadiene 1-3 produced.
