  摘要：

  芳香基甲酸酯4a-u、6、8、10、12、14、16、18、20、22、24、26是通过羟基芳香化合物3a-u、5、7、9、11、13、15、17、19、21、23、25分别与N,N-二甲酰乙酰胺（1）或三甲酰胺（2）甲酰化反应得到的，产率相当不错。这些反应可以通过二甲酰胺钠或镨(III)三氟甲磺酸催化。巯基甲酸酯28是类似地从1-硫代萘酚（27）得到的。

  A method for forming a monomeric carbonate includes the step of combining a monofunctional alcohol or a difunctional diol with an ester-substituted diaryl carbonate to form a reaction mixture. Similarly, a method for forming a monomeric ester includes the step of combining a monofunctional carboxylic acid or ester with an ester-substituted diaryl carbonate to form a reaction mixture. These methods further include the step of allowing the reaction mixtures to react to form a monomeric carbonate or a monomeric ester, respectively.

  形成单体碳酸酯的方法包括将单官能醇或双官能二元醇与酯基取代的二芳基碳酸酯结合以形成反应混合物的步骤。类似地，形成单体酯的方法包括将单官能羧酸或酯与酯基取代的二芳基碳酸酯结合以形成反应混合物的步骤。这些方法进一步包括允许反应混合物反应以分别形成单体碳酸酯或单体酯的步骤。

  The relative intensity of fluorescent light of a melt-polycondensed aromatic polycarbonate produced by the transesterification process (melt polymerization process) of an aromatic dihydroxy compound and a carbonic acid diester in the presence of a catalyst comprising a basic nitrogen compound and/or a basic phosphorus compound in combination with an alkali metal compound is suppressed to 4.0×10-3 or below at a wavelength of 465 nm based on a standard substance in a fluorescent light spectrum obtained by the excitation wavelength of 320 nm. An aromatic polycarbonate having good color stability, especially good stability to the deterioration of the chip color during storage of the chip in air at room temperature can be produced by the present invention..
