ABSTRACT
Vacuum pyrolysis of phenolic resin laminate substrate in temperature-programmed furnace reactor was studied.The sample and product oils were characterized by elemental analysis, Fourier transform infrared (FT-IR) analysis and gas chromatography-mass spectrometry(GC-MS).Analytical results showed that the up per clear liquid of pyrolysis oils was mainly consisted of water-soluble substances, such as phenol, cresol, xy lenol, sugars, hydantoins, morpholines, pyranones and pyridine derivatives compounds, etc., while the lower sediment was mainly insoluble or hardly water-soluble substances, such as the big substituent phenolics (the number of substituent carbon atoms of which is greater than or equal to 2), aryl phosphate esters, fatty acid esters and nitrile compounds, and so on.Both of the upper clear liquid and lower sediment have a higher content of melamines.
