3-(10-Phenyldecyl)catechol was synthesized by the reaction of catechol and 1-phenyl-10-iododecane, followed by de-protection of the hydroxyl groups of catechol; it was then polymerized into synthetic lacquer film by laccase enzyme, and characterized using pyrolysis-gas chromatography/mass spectromet
Laccol, a major component of lacquer sap from Rhus succedanea, was synthesized by a Witting reaction, and then mixed with acetone powder separated from raw lacquer sap to synthesize lacquer films. The resulting lacquer films were analyzed by pyrolysis gas chromatography/mass spectrometry (Py-GC/MS),
Melanorrhoea usitate lacquer film was investigated using two-stage pyrolysislgas chromatography/mass spectrometry. Monoenyl and saturated thitsiol components were detected by pyrolysis at 400 "C. The pyrolysis products of the thitsiol polymer, i.e. alkenes, alkanes, akenylbenzenes, alkylbenzenes, al
