Abstract
The thermal behavior of vitamin D~3~ was studied based on pyrolysis‐GC‐MS technique. It was pyrolyzed at 600 °C, 750 °C, 900 °C, respectively. The pyrolysis product were separated With an HP‐5 column and identified by the NIST mass spectral search program in combination with the correlation of boiling point and retention time (BP‐RT). There are totally 50 components, including mono aromatics and polycyclic aromatic hydrocarbons (PAHs), were determined. It is shown that the contents of the PAHs are increasing with the increasing of the pyrolysis temperature. The contents of the determined components vary from 0.04 % to 37.08 %.
