[0228] Example
[0229] Hereinafter, examples are shown to further specifically explain the present invention. However, the present invention is not limited to the following examples, and can be implemented with arbitrarily changed without departing from the gist of the present invention.
[0230] The raw material components used in the following Examples and Comparative Examples are shown in Table 1 below.
[0231] [Table 1]
[0232]
[0233] In Table 1 above, the polycarbonate resins (B1) and (B2) used as the polycarbonate resin (B) were produced by the following production examples.
Example Embodiment
[0234]
[0235] Put 2,2-bis(3-methyl-4-hydroxyphenyl)propane (hereinafter referred to as "BPC") in a SUS reactor (10 liters of internal volume) equipped with a stirrer and a distillation condenser. 26.14 Mol (6.75 kg) and 26.79 mol (5.74 kg) of diphenyl carbonate, the inside of the reactor was replaced with nitrogen, and the temperature was raised to 220°C in 30 minutes under a nitrogen atmosphere.
[0236] Next, the reaction liquid in the reactor was stirred, and cesium carbonate (Cs 2 CO 3 ), making it 1.5×10 relative to 1 mole of BPC -6 Mole, the reaction solution was stirred and matured at 220°C for 30 minutes under a nitrogen atmosphere. Next, the pressure in the reactor was reduced to 100 Torr over 40 minutes at the same temperature, and further reacted for 100 minutes to distill phenol.
[0237] Next, the temperature in the reactor was increased to 284° C. and the pressure was reduced to 3 Torr over 60 minutes to distill out the basic total amount of phenol corresponding to ...
Example Embodiment
[0242]
[0243] 26.14 moles (6.75 kg) of BPC and 26.79 moles (5.74 kg) of diphenyl carbonate were placed in a SUS reactor (10 liters of internal volume) equipped with a stirrer and a distillation condenser, and the reactor was replaced with nitrogen. After that, the temperature was raised to 220°C in 30 minutes under a nitrogen atmosphere.
[0244] Next, the reaction liquid in the reactor was stirred, and cesium carbonate (Cs 2 CO 3 ) To make it 1.5×10 relative to 1 mole of BPC -6 Mole, the reaction solution was stirred and matured at 220°C for 30 minutes under a nitrogen atmosphere. Next, the pressure in the reactor was reduced to 100 Torr over 40 minutes at the same temperature, and the reaction was further performed for 100 minutes to distill phenol.
[0245] Next, the temperature in the reactor was increased to 284° C. and the pressure was reduced to 3 Torr over 60 minutes to distill out the basic total amount of phenol corresponding to the theoretical amount of distillation. ...
