摘要
为使落叶松心材适应于化学机械法制浆（ＣＭＰ），本研究通过分离、提纯落叶松心材多酚类抽提物，用红外光谱、紫外光谱和１３Ｃ—ＮＭＲ波谱对此抽提物进行了分析，确认了该抽提物的化学组成及化学结构，为进一步研究落叶松心材的制浆性能提供了理论依据。
In order to fit in with the needs of making the CMP with larch(L.gmelini)heartwood.we dissociate the polyphenols from larch heartwood and analyse it with IR、UV and13C-NMR in the study.By the study we have confirmed the chemical constitute and chemical structure of the polyphenols.Meanwhile,we have got the theoretical basis that can be used to study the pulping characteristic of larch heartwood in the future.
