On March 31, 2020, Liu, Tao; Yuan, Xiaoxue; Zhang, Gang; Hu, Jing; An, Jing; Chen, Tong; Wang, Gongying published an article.Name: Phenyl Salicylate The title of the article was Stir bar sorptive extraction and automatic two-stage thermal desorption-gas chromatography-mass spectrometry for trace analysis of the byproducts from diphenyl carbonate synthesis. And the article contained the following:
In this study, a fast and sensitive method based on stir bar sorptive extraction (SBSE) and two-step thermal desorption coupled with online gas chromatog.-mass spectrometry was established to simultaneously analyze six trace byproducts [phenyl salicylate (PS), xanthone (XA), Me o-hydroxybenzoate (MS), 2-Me di-Ph carbonate (PTC), Me o-methoxybenzoate (MSME) and Ph o-methoxybenzoate (PSME)] generated in the process of di-Ph carbonate (DPC) synthesis. Under the optimal conditions, the six byproducts generated in the synthesis of DPC via transesterification were quant. analyzed by external standard method. The results showed that, within the range of 1.0-100 ng/L for all of the six transesterification byproducts, this method revealed good linearity with correlation coefficients (r) ≥0.997. The limits of detection (LODs) were between 0.054 ng/L and 0.253 ng/L, the relative standard deviations (RSD) were from 5.2% to 11.5%, and the recoveries were 81.6%-102.6% (n = 3). The method is simple, rapid and has a wide linear range, high accuracy, and sensitivity, as well as good stability. It is suitable for simultaneous, rapid and selective anal. of six trace byproducts in the process of DPC synthesis. It can also provide vigorous data support and industrialization guidance for the selection of transesterification conditions and research on the formation mechanisms, distribution regularity, and even control of transesterification byproducts. The experimental process involved the reaction of Phenyl Salicylate(cas: 118-55-8).Name: Phenyl Salicylate
