摘要：
Poplar composite biomaterial. which self bonded under high temperature and pressure. is a new indoors materials. In order to evaluate its potential health risk to human settlements, the volatile organic compounds of poplar composite biomaterial were adsorbed and determined by TD-GC-MS. The result were: (1) The main constituents of volatiles at 40 degrees C were acetic acid(50.6%). 1,2-benzenedicarboxylic acid. mono(2-ethylhexyl) ester(8.48%), [1,1':3',1 ''-terphenyl]-2'-ol(3.98%). 1,2-propanediol, 3-benzyloxy-1,2-d iacetyl-(3.12%). etc. (2) The main constituents of volatiles at 60 degrees C were acetic acid(46.7%). 1,2-benzenedicarboxylic acid, mono(2-ethylhexyl) ester(7.93%), cedrol(5.53%), butane. 1-(benzyloxy)-2-[(benzylox y)methyl]- (5.43%), [1,1':3',1 ''-terphenyl]-2'-ol(3.72%), 1-propene, 3-(2-cyclopentenyl)-2-m ethyl-1,1- diphenyl-(3.18%), etc. Generally, the poplar composite biomaterial was safe under 40-60 degrees C.
摘要：
The volatiles materials is the first killer to damage the lives of indoor air pollutions. Based on the single-factor method, volatiles of temperature-pressure forming materials by cotton stalk was studied by Py-GC/MS to control indoor air pollutions. Therefore, Py-GC/MS was used to analyze the components from pyrolysis products of temperature-pressure forming materials by cotton stalk,. After treated with freeze-drying, the comminuted power of temperature-pressure forming materials by cotton stalk was pyrolyzed in He atmosphere at 450 degrees C, then the pyrolysis product was analyzed by online linked GC/MS. Relative content of each component was determined by area normalization. The main and abundant constituents were arbon dioxide, ethene, ethoxy-, 1,6-anhydro-.beta.-D-glucopyranose, phenol, 2-methoxy-4-(1-propenyl)-, cedrol, thylene oxide, butanal, ethanone, 1-phenyl-, oxime, and so on. More than 30 compounds were identified in the pyrolysis products of Cotton stalk by the Py-GC/MS analysis. Most of the pyrolysis products could be used as biomedicine. But some of the volatiles of temperature-pressure forming materials by cotton stalk was toxic. And this meant that cotton stalk need be pretreatment.
