Tyladipate (DBA), bis(2-butoxyethyl)adipate, BBOEA and hexane
Di(2-ethylhexyl)adipate (DEHA).
2.2
Internal standard. bis(1-butylpentyl)adipate (BBPA).
3 Method summary
The sample was ultrasonically extracted with isopropyl alcohol, and the extract was fixed to volume and then detected by gas chromatography-mass spectrometry and quantified by internal standard method.
4 reagents and materials
Unless otherwise specified, the reagents used should be of analytical grade.
4.1 Isopropanol.
4.2 DEHA and other adipate plasticizer standards. purity ≥ 98%.
4.3 DEHA and other adipate plasticizer standard stock solution. accurately weigh the appropriate amount of DEHA and other adipate plasticizer
The standard product was prepared into a standard stock solution with a concentration of 10 mg/mL using isopropyl alcohol.
4.4 Internal standard. di(1-butylpentyl) adipate. purity ≥98%.
