Method for producing polycarbonate |
| abstract |
An integrated method for producing aromatic polycarbonate, including the steps of:n (1) making a liquid mixture of acetone and diphenylcarbonate; (2) transporting the liquid mixture of step (1) to a polycarbonate production plant; (3) separating the diphenylcarbonate from the acetone in the liquid mixture in the polycarbonate production plant; (4) reacting the diphenylcarbonate with bisphenolacetone to produce polycarbonate, thereby liberating phenol; (5) reacting phenol of step (4) with acetone of step (3) to produce bisphenolacetone; (6) using bisphenolacetone of step (5) in the reaction of step (4). |
