| 1 | Wood liquefaction with phenol by microwave heating and FTIR evaluation显示文摘We examined wood liquefaction using phenol and mixed acid catalysts with microwave heating, and compared that with similar processes that use oil bath heating. The reaction time for microwave heating to achieve a residue content was one sixth, one eighteenth,and one twenty-fourth of that from oil bath heating,respectively, for phenol to wood(P/W) ratios of 2.5/1, 2/1and 1.5/1. A low P/W ratio tended to result in carbonization of liquefied wood due to an insufficient amount of phenol and localized microwave superheating. Fourier transform infrared spectroscopic(FTIR) evaluation of the liquefied residue, showed that the liquefaction rates of wood components differed. Hemicellulose was most susceptible to liquefaction, crystalline cellulose was most recalcitrant,and guaiacyl units the most prone to re-condensation. From FTIR, the chemical components and substitution patterns of bonded phenol were similar for both methods. | Gaiyun Li Chungyun Hse Tefu Qin | 2015 | Journal of Forestry Research2015，26，4： | 3 |

| 12 | Study on Volatile Organic Components from Chinese Fir Wood显示文摘The volatile organic compounds(VOCs) are emitted by a wide array of products, which include a variety of chemicals, some of them may have short- and long-term adverse health effects. Several analytical instrument including gas chromatograph, high preferment liquid chromatograph, mass spectrometry and solid phase microextraction (SPME) technique were used in this study. The results showed the aldehyde and ketone components of Chinese fir wood were little composed of formaldehyde, syn- acetaldehyde, anti-acetadehyde and acrolein, VOCs obtained by Tenax GR absorber consisted of the major component cedrene (42.92%) and another 28 components, and the major components of the VOCs from the sample by using solid phase microextraction (SPME) technique were cedrene and cedrol. | HUANG Luohua QIN Tefu OHIRA Tatsuro | 2006 | Chinese Forestry Science and Technology2006，5，3： | 0 |
| 13 | Investigation of Carbohydrate Compositions for Poplar I-214 and Chinese Fir显示文摘The carbohydrate compositions of poplar I-214 and Chinese fir were investigated by the methods of hydrolysis and HPLC. The result showed that the contents of glucose, xylose and arabinose in poplar I-214 are higher than those in Chinese fir, while contents of rhamnose and mannose in poplar I-214 are lower than those in Chinese fir. | HUANG Luohua QIN Tefu MAGARA Kengo | 2006 | Chinese Forestry Science and Technology2006，5，4： | 0 |
| 14 | Study on Chemical Components and Properties of Radial Chinese Fir显示文摘The variability of main chemical composition of radial Chinese fir was studied. Analysis of variance showed that variance was significant, especially for holocellulose and α-cellulose; the holocellulose content in heart wood was lower than that in sapwood; the lignin content decreased from Position 1 to Position 3, but increased gradually from Position 4 to Position 8; the α - cellulose content in heart wood was lower than that in sapwood; and the relative crystallinity was 59.97% in Position 1, 60.80% in Position 2, and about 42% in others. | HUANG Luohua QIN Tefu | 2007 | Chinese Forestry Science and Technology2007，6，3： | 0 |
| 15 | Study on Essential Oil Extracted from Camphor Tree Wood显示文摘Essential oil of camphor tree wood was analyzed by GC-MS system, thirty-three components of which were identified. The essential oil is consisted of monoterpenes and sesquiterpepes (43.73%), fatty acids (26.61%), unsaturated fatty acids, ketone and aldehyde components. | HUANG Luohua QIN Tefu ZHOU Qin LU Xixian | 2005 | Chinese Forestry Science and Technology2005，4，4： | 0 |
