In order to comprehensive understand and control volatile organic compounds (VOCs) release from particleboards, this paper takes Larix gmelini particleboard as example and analysis VOCs from raw materials. In the first, VOCs of Larix gmelini particles were detected. Secondly urea-formaldehyde resin (UF) adhesive and Larix gmelini particleboard were analyzed using the method of Thermal desorption -GC/MS to qualitative VOCs emissions. At last, source of VOCs was found theoretically through comparison the differences of raw materials. The result of experiments revealed that VOCs from particleboards include alkane, terpenes, aromatic hydrocarbon, alcohol, aldehyde, and ester and so on. The highest group of Larix gmelini particles was α -pinene (33.4%), followed by β-phellandrene (13.0%), hexanal (11.3%). 46 kinds of compounds were identified in UF adhesive. The main VOCs in UF adhesive are toluene, styrene, furfural and benzaldehyde, pentadecane etc. Mix of UF adhesive and wood shavings were identified 54 matters. The highest group was hexanal (67.02%) followed by 2-pentyl-furan(7.97%), α -pinene(5.10%). 63 kinds of compounds were analyzed and identified in particleboards. The highest group was hexanal (8.59%) followed by naphthalene (7.92%), 1-butoxy-2-propyl alcohol(6.60%), 2- butoxy - alcohol(6.47%), Nonanal (5.66%). Toluene and benzaldehyde derived from UF adhesive furfural and benzaldehyde maybe have a chemical reaction after pressing. We can judge hexanal, α -pinene, 1-methylnaph- halene and nonanal from Larix gmelini particles.
