摘　　要：以毛竹和重组竹为研究对象,采用热裂解-气相色谱-质谱(PY-GC/MS)对其裂解产物进行定性分析,考察两者热裂解产物的分布差异。结果表明,毛竹和重组竹热裂解后均产生了酚类、醛酮类、呋喃类、醇酯类和酸类物质。在热裂解产物中,毛竹和重组竹热裂解酚类产物的气相色谱(GC)含量明显不同,毛竹中酚类产物的GC含量仅为8.23%,而重组竹中酚类产物GC含量高达26.36%;毛竹热裂解醛酮类产物和呋喃类产物的GC含量均高于重组竹;毛竹与重组竹热裂解醇酯类产物的GC含量差异不大;重组竹热裂解酸类产物的GC含量均高于毛竹。此外,重组竹中酚醛树脂的热裂解进一步加速了竹材的热裂解过程。In this study,moso bamboo and bamboo scrimber were regarded as the research objects,and their pyrolysis products were qualitatively analyzed by PY-GC/MS.The difference of volatile gas escaped between moso bamboo and bamboo scrimber was also investigated.The results showed that phenolic products,aldehydes-ketones products,furan products,ester products,alcohol products and acid products were detected during the pyrolysis of moso bamboo and bamboo scrimber.In the pyrolysis products,the GC content of phenolic products was significantly different between moso bamboo and bamboo scrimber.The GC content of phenolic substances in moso bamboo was 8.23%,while the GC content of phenolic substances in recombinant bamboo was as high as 26.36%.The GC content of aldehyde-ketone products and furan products from pyrolysis of moso bamboo was higher than that of bamboo scrimber.There was no significant difference in GC content of alcohol ester products between moso bamboo and bamboo scrimber.The GC content of acid products of bamboo scrimber was higher than that of moso bamboo.In addition,the pyrolysis of phenolic resin in bamboo scrimber accelerated the pyrolysis process of bamboo in it.
