摘要： The present invention relates to a process for obtaining a dialkyl phthalate and a reusable target PVC plastic from a PVC feedstock containing at least one phthalate, including:
a) a solid-liquid extraction of said PVC feedstock in the form of particles by placing said particles of the PVC feedstock in contact with a solvent including at least one alcohol CnH2n+1OH with n 8, to produce a liquid phase enriched in said phthalate and a solid phase including PVC plastic depleted in said phthalate;
b) transformation of said phthalate of said liquid phase into dialkyl phthalate of formula C6H4(COOCnH2n+1)2 by transesterification using said alcohol;
c) a solid-liquid separation between the solid phase and the liquid phase to produce at least one solid stream including the PVC plastic depleted in said phthalate so as to obtain said target PVC plastic;
d) a liquid-liquid separation of the liquid phase, to produce at least a first liquid effluent including said dialkyl phthalate and a second liquid effluent comprising said solvent.
