3 Terms and Definitions
The following terms and definitions apply to this document.
3.1
photoinitiator photoinitiator
A reactive intermediate (free radical or cation) that can absorb radiation energy and undergo chemical changes upon excitation
substance.
4 Principles
Using butyl acetate and other solvents as the extraction solvent, the photoinitiators in the test samples were extracted by ultrasonic. After the extract was quantified, it was analyzed by gas chromatography-mass spectrometry.
Spectrometry was used for detection and external standard method for quantification.
5 Reagents and Materials
Unless otherwise specified, only reagents confirmed to be analytically pure and above are used in the analysis.
5.1 Butyl acetate. of analytical or known purity, does not contain any substances that interfere with the test. Alternatively, a proven recovery equivalent can be selected.
Take a solvent, such as acetone, ethanol, ethyl acetate, acetonitrile, n-hexane, cyclohexane, etc.
5.2 Photoinitiator calibration compound. purity ≥98% (mass fraction) or known purity, list of commonly used photoinitiators for radiation curing coatings
