Abstract

La présente invention concerne un procédé de purification d’une charge monomère diester brute comprenant : a) une étape de mélange de la charge monomère diester brute avec un solvant aqueux, à une température entre 60 et 150°C, pour obtenir un mélange aqueux de monomère diester, la quantité de solvant aqueux introduit étant ajustée de sorte que la charge monomère diester brute représente entre 20 et 90%, du poids total du mélange aqueux de monomère diester ; b) une étape d’adsorption du mélange aqueux de monomère diester, à une température entre 60 et 150°C et une pression entre 0,1 et 1,0 MPa, pour obtenir un effluent monomère purifié.
