| titleOfInvention | process for producing a bisphenol a product, process for preparing polycarbonate, and container |
| abstract | A process for producing a bisphenol a product, a process for preparing polycarbonate, and a container in one embodiment, a process for producing a bisphenol a product comprises: reacting phenol with acetone in the presence of a sulfur containing promoter to obtain a reaction mixture comprising the bisphenol a, phenol, and promoter; upon reacting phenol with acetone, cooling to form a crystal flow comprising bisphenol a and phenol crystals; separate crystals from crystal flow; melting the crystals to form a molten flux of bisphenol a, phenol, and sulfur; contacting the molten stream with a base to reduce sulfur concentration in the molten stream and forming a reduced sulfur stream; and removing phenol from the reduced sulfur stream to form a bisphenol product a. Also reported herein is a container comprising: a polycarbonate formed from a bisphenol a having a sulfur concentration of 0.5 to 15 ppm based on the weight of bisphenol a. 3 1/1 |
