However, industrial implementation faces stability challenges due to chromatic deterioration (yellowness index increasing from 0.94 to 2.12) and declining purity. Prolonged storage (&gt;20 h at 110°C) of depolymerization mixture (i.e., the PC methanolysis reaction mixture) causes instability. Trace colored by‐products, which were undetectable by FT‐IR, arose from the oxidation of the phenolic hydroxyl groups of bisphenol A, the formation of conjugated structures, and the thermal conversion of feedstock impurities. High performance liquid chromatography tracking revealed that thermally sensitive unknown impurities (retention time: 38.4 min) were the primary cause of purity loss. Xenon lamp aging experiments confirmed that feedstock degradation exacerbates product defects: aged polycarbonate increased impurities in crude bisphenol A, reduced molecular weight by 3.8%, and significantly worsened chromaticity (b* value increased by 552%). Tetramethylammonium hydroxide exhibits superior catalytic performance over NaOH in suppressing chromophore aggregation. This enhancement is ascribed to the steric hindrance and electronic effects arising from its quaternary ammonium cation (N(CH<sub>3</sub>)<sub>4</sub><sup>+</sup>). A toluene recrystallization process achieved a bisphenol A purity of 98.85%. These findings offer critical guidance for industrial buffer tank design and catalyst selection, advancing the development of sustainable polycarbonate recycling technologies.</div></div>","PeriodicalId":130,"journal":{"name":"Asian Journal of Organic Chemistry","volume":"15 7","pages":"Article e70500"},"PeriodicalIF":2.3,"publicationDate":"2026-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148615795","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
