关于热化学分解的热解物，检查了以下内容。(1)常规热解与热化学解热解产物的热值比较。(2)聚合物是通过酶裂解制备的。在（1）中，通过常规热解或热化学解的热解产物通过GC/MS分析以确定其结构。此外，通过GC-FID定量每种热解物含量。此外，估计的燃烧能量计算每种热解物。结果表明，在400、500和600℃下，四丁基氢氧化铵热化学分解比常规热解可使相思树皮的燃烧能提高90-120 J/g。考虑到每种热解产物，例如，对于桉树树皮样品，通过用四丁基氢氧化铵热化学分解获得的3，4，5-三丁氧基苯甲酸丁酯与通过常规热解获得的相应3，4，5-三羟基苯甲酸相比，显示出约16 kJ/g的燃烧能量增加。在（2）中，部分热解产物在有机溶剂/缓冲溶液（甲醇和磷酸缓冲溶液的混合物）中与辣根过氧化物酶聚合。结果，通过SEC测得平均分子量为2，000 - 3，000，聚合物的份数为约18，000。在热化学分解仪的研制中，该系统基本得到了验证。新仪器的优点如下。（1）减少记忆效应，这将通过减少在热解管中引起下一样品污染的残留热解物而提供更高的再现性，和（2）自动化。

On pyrolyzates by thermochemolysis, the followings were examined. (1) Comparison in calorie of pyrolyzates by conventional pyrolysis to by thermochemolysis. (2) Polymer was prepared by pyrolyzates with enzymes. In (1), the pyrolyzates by conventional pyrolysis or thermochemolysis were analyzed by GC/MS to determine their structures. Furthermore, each pyrolyzate content was quantified by GC-FID. Moreover, estimated combustion energy was calculated for each pyrolyzates. As a result, combustion energy was increased in 90-120 J/g by thermochemolysis with tetrabutylammoniumhydroxide compared to conventional pyrolysis at 400, 500 and 600℃ for acacia bark sample. Considered by each pyrolyzates, for example, 3,4,5-tributoxy benzoic acid butyl ester obtained by thermochemolysis with tetrabutylammoniumhydroxide for eucalypt bark sample showed about 16 kJ/g increase in combustion energy compared to the corresponding 3,4,5-trihydroxy benzoic acid obtained by conventional pyrolysis. In (2), part of pyrolyzates were polymerized in organic solvent/buffer solution mixture of methanol and phosphoric acid buffer solution with horse radish peroxidase. As a result, the average molecular weight was measured as 2,000-3,000 and part of polymer was about 18,000 by SEC. In the development of thermochemolysis instrument, the system was almost confirmed. The advantages of new instrument were as follows. (1)Reduction of memory effect which will give higher reproducibility by the reduction of remaining pyrolyzates in pyrolysis tube causing contamination in the following sample, and (2)automation.
