At present, the production methods of polycarbonate mainly includesolution phosgene, ester exchange, interfacial polycondensationphosgene and non-phosgene. 1 Solution Phosgene, a process in whichphosgene is introduced into an alkaline aqueous solution containingBISPHENOL A and a solvent containing dichloromethane to perform aninterfacial polycondensation reaction, and then the polymer isseparated from the solution. Compared with other productionmethods, the solution phosgene method has been completelyeliminated because of its poor economy. Transesterification, alsoknown as the traditional melting process, is also an indirectphosgene process. It is a phenol raw material, after phosgenereaction to produce diphenyl carbonate, and then lithium halidesand other catalysts and in the presence of Transesterification andBisphenol a, to produce oligomers, in further polycondensation topolycarbonate. Although the cost of this process is lower than thatof other processes, the polycarbonate produced by this process haspoor optical properties, the catalyst is easy to be polluted, andthe molecular weight of the product is low due to the presence ofthe by-product phenol, therefore, the commercial application ofthis process is limited. 3 The process of Interfacialpolycondensation and phosgene is to prepare bisphenol a sodium saltfrom BISPHENOL A and caustic soda solution, at the same time to addphenol, and then to the phosgene reactor. The dichloromethane isadded to the polycondensation reactor and the reaction is carriedout by phosgene. After the reaction is completed, the reactionliquid is sent to the polycondensation reactor, and triethylamineand caustic soda solution are added for the polycondensationreaction. The organic phase containing polymer is then separatedfrom the water phase, and the organic phase is washed, dried andthen granulated to obtain the finished polycarbonate product. 4 Thenon phosgene method, the non phosgene method is to producepolycarbonate by liquid phase oxidation carbon based method, thento exchange with phenyl Acetate to produce diphenyl carbonate, thento exchange with bisphenol a in the melting state, and topolycondense polycarbonate. Therefore, no by-products, basicnon-pollution, especially not the use of highly toxic phosgene,which is highly valued by the world's major companies, have beencommitted to development. To sum up, the non-phosgene process is acompletely closed, non-by-product, less pollution and environmentalrequirements of the green process, has been successfully studied byforeign companies, but as domestic research and development isstill in progress, the process is not mature, this design does notuse, but the interfacial condensation phosgene process is mature,reflected in normal temperature and pressure, the equipmentrequirements are not high, product quality, especially by the endof 2004, the world's total production capacity of polycarbonateclose to 3.3 mt / A. Phosgene process is about 90% of the totalproduction capacity. So this design uses the interface condensationphosgene method.
