    摘要： Provided is a method of recycling a waste resin composition containing a synthetic resin and organic impurities. A method of manufacturing a dihydroxy compound from a waste resin composition, the method including, a step (a1) in which an alkaline solution containing a first solvent, water, and a waste resin composition containing a resin having at least two constitutional units selected from the group consisting of general formulae (1) to (4) set forth below:




    is treated to give a reaction solution containing a first solvent and a mixture of dihydroxy compounds containing a first dihydroxy compound selected from the group consisting of general formulae (1') to (4') set forth below:




    and at least one other dihydroxy compound selected from the group consisting of the general formulae (1') to (4'); and a step (b1) in which the first dihydroxy compound is crystallized from a crystallization solution obtained by adding a second solvent to the reaction solution, wherein a difference between the solubility of the first dihydroxy compound at 25°C in the second solvent and the solubility of the other dihydroxy compound at 25°C in the second solvent (solubility of the other dihydroxy compound minus solubility of the first dihydroxy compound) is greater than or equal to 0.1 g/(10 mL).
