The invention relates to a process for preparing a specific hydroxy compound by means of decarboxylation of a specific carboxylic acid compound or a salt of said carboxylic acid compound, to a method for preparing a diaryl carbonate, a bisphenol or a polycarbonate, a diaryl carbonate or bisphenol, a polycarbonate, and to a method for adjusting the isotope ratio of C14 to C12 in a polymer. A specific solvent is used during decarboxylation. 本发明涉及通过使特定的羧酸化合物或所述羧酸化合物的盐脱羧来制备特定的羟基化合物的方法，涉及制备碳酸二芳基酯、双酚或聚碳酸酯的方法，涉及碳酸二芳基酯或双酚、聚碳酸酯，以及涉及调节聚合物中C14与C12的同位素比率的方法。在此，在脱羧期间使用特定的溶剂。
