synthesis example 1
Synthesis of 1,1-Bis(4-hydroxyphenyl)decane (BP-C10)
[0180]A synthesis example of 1,1-bis(4-hydroxyphenyl)decane, which is listed in the later-mentioned Table-1, is described below.
[0181]Phenol (100 parts by weight) was melted by warming at 40° C., and concentrated hydrochloric acid (1.33 parts by weight) was added thereto. To the resulting mixture, a mixture of decanal (33.1 parts by weight) and toluene (21.2 parts by weight) was added dropwise for four hours. Thereafter, the mixture was aged at 40° C. for 1 hour, and the reaction was stopped with an aqueous sodium hydrogen carbonate solution. After evaporating phenol from the reaction mixture under reduced pressure, extraction was performed with toluene, and the mixture was washed with water three times. After removing the solvent by distillation, crystallization from toluene and heptane was performed to obtain 23.3 parts by weight of the compound of interest as a white powder. The purity was 99.4%, and the melting point was 93° C....
synthesis example 2
Synthesis of 1,1-Bis(4-hydroxyphenyl)dodecane (BP-C12)
[0182]A synthesis example of 1,1-bis(4-hydroxyphenyl)dodecane, which is listed in the later-mentioned Table-1, is described below.
[0183]The same synthesis as in Synthesis Example 1 was carried out except that dodecanal (39.0 parts by weight) was used instead of decanal. As a result, 27.8 parts by weight of the compound of interest was obtained as a white powder. The purity was 99.0%, and the melting point was 86° C.
[0184]The compounds of interest in Synthesis Examples 1 and 2 were analyzed under the following analysis conditions.
[Purity]
[0185]In 1 part by mass of acetonitrile, 0.01 part by mass of a sample was dissolved. The obtained solution was analyzed using an HPLC analyzer (LC-2010, manufactured by Shimadzu Corporation). The conditions were as follows.
[0186]Column: Inertsil ODS3V (manufactured by GL Sciences Inc.)
[0187]Eluting solvent: acetonitrile / 0.1% by mass ammonium acetate solution
[0188]Detector: UV (254 nm)

production example 1
of Aromatic Polycarbonate Copolymer
[0192]The material dihydroxy compounds and the carbonate-forming compound described in Table-1 were fed to a glass reactor having a capacity of 150 mL equipped with a reactor heater and a reactor pressure regulator, at the material feed ratios described in Table-2, such that the total amount of dihydroxy compounds was 117 g. Further, as a catalyst, 2 wt % aqueous cesium carbonate solution was added thereto such that cesium carbonate was contained at 1 μmol per 1 mol of the total dihydroxy compounds, to prepare a material mixture.
[0193]Subsequently, an operation of reducing the pressure in the glass reactor to about 100 Pa (0.75 Torr) and then restoring the pressure with nitrogen to atmospheric pressure was repeated three times, thereby replacing the inside of the reactor with nitrogen. Thereafter, the external temperature of the reactor was adjusted to 220° C. to allow a slow increase in the internal temperature of the reactor, thereby dissolving t...
