Thitsiol
WebIt is an unexpected result that the lacquer in this pottery container is actually used by Melanorrhoea usitata. Alkylbenzene and alkenylbenzene as cleavage pieces of undecylbenzene (MW = 232 g/mol) and undecenylbenzene (MW = 230 g/mol), which are products of the pyrolysis of thitsiol, were detected in all three samples. WebIn addition, the monomer, dimer, trimer, and tetramer fractions of thitsiol of Thailand raw lacquer were separated by HPLC and analyzed by NMR spectroscopy. Almost all proton and carbon NMR peaks were assigned, and the structure of thitsiol was confirmed. Original language: English: Pages (from-to) 68-75:
