Method for producing dimethyl terephthalate by polyester methanol decomposition depolymerization system |
| abstract |
A depolymerization method for polyesters is disclosed. The method includes (a) treating the polyester with methanol under conditions sufficient to depolymerize at least some of the polyester and form a reaction product comprising dimethyl terephthalate and at least one glycol; and (b) The diol is converted to a compound that is substantially unreactive with the dimethyl terephthalate and polyester. A method for producing cyclic carbonates is also described. |
