A solid phase extraction-gas chromatog. tandem mass spectrometry (SPE-GC/MS) method was established for the anal. of 18 phthalate plasticizers in waste cotton. The research results showed that when the sample was extracted with Et acetate-n-hexane (1: 3, V/V), enriched and purified with the HC-C18 solid phase extraction column, separated with the HP-5 MS capillary column, analyzed with the selected ion scanning (SIM) mode and external standard method for quantification, good linear relationships were found for 18 plasticizers in the range of 0.1-10 娓璯/mL (DIHP, DINP, DIDP were 0.5-50 娓璯/mL). The correlation coefficient was 0.9959-1.0000, the detection limit was 0.051-1.73 娓璯/g, and the quantification limit was 0.24-6.94 娓璯/g, resp. At the spiked levels of 0.2, 1, and 5 娓璯/mL, the recoveries of the 18 plasticizers were 82.2-104.7%, and the intra-day and inter-day relative standard deviations were 1.1-7.9% and 0.8-8.3%, resp. This method is suitable for the anal. of phthalate plasticizers in waste cotton. In the experiment, the researchers used many compounds, for example, Dicyclohexyl phthalate (cas: 84-61-7Application In Synthesis of Dicyclohexyl phthalate).
Dicyclohexyl phthalate (cas: 84-61-7) belongs to esters. Carboxylic acid esters of low molecular weight are colourless, volatile liquids with pleasant odours, slightly soluble in water. Because of their lack of hydrogen-bond-donating ability, esters do not self-associate. Consequently, esters are more volatile than carboxylic acids of similar molecular weight.Application In Synthesis of Dicyclohexyl phthalate
