Method for producing a terephthalate polyester from a monomeric mixture comprising a diester |
| abstract |
The aim of the invention is a method for producing a terephthalate polyester, comprising a step a) of preparing an esterification charge comprising at least one mixing section fed with at least one terephthalic acid charge and a diester monomer charge, so that the ratio of the total number of moles of diol units introduced into said mixing section to the total number of moles of terephthalate units introduced into said mixing section is between 1.0 and 2.0, said mixing section being operated at a temperature between 25 and 250°C and at a pressure that is greater than or equal to 0.1 MPa; a step b) of esterification for producing at least one reaction effluent and one aqueous effluent; a step c) of polycondensation for obtaining at least said terephthalate polyester and an effluent comprising at least one diol monomer; and a step d) of treating diols in order to obtain a purified diol stream. |
