| titleOfInvention | Manufacturing apparatus of polycarbonate resin, and manufacturing method of polycarbonate resin |
| abstract | The subject of this invention relates to providing the manufacturing apparatus of the polycarbonate resin by which generation | occurrence | production of the deposit and the foreign material in a polymerization tank was reduced, and the manufacturing method of the polycarbonate resin by which the crystallization foreign material and burning foreign material by the melting method were reduced.n n n The present invention provides a continuous production apparatus for a polycarbonate resin using a plurality of polymerization tanks, wherein the polymerization reaction liquid is supplied to the gas phase portion in the polymerization tank in the liquid phase in the polymerization tank or by an insertion tube in at least one polymerization tank. And / or When the polycarbonate resin by transesterification of an aromatic dihydroxy compound and a carbonic acid diester is produced using three aqueous polymerization tanks equipped with a stirring device and one horizontal polymerization tank, at least a third aqueous type So that the relationship between the boiling point t1 of the by-product phenol in the pressure in the polymerization tank 14, the wall surface temperature T of the outflow pipe 10c, and the internal temperature t2 of the third male polymerization tank 14 satisfies Expression (1), This relates to setting the wall surface temperature T of the outlet pipe 10c to a higher temperature than the boiling point t1 of the by-product phenol.n n n t1 <T ≤ t2 (1) |
