落叶松及其磺化化机浆中阿拉伯糖基4-O-甲基葡萄糖醛酸木聚糖的红外光谱分析

IR Analysis of Aralino-4-O-Methyl-Glucorono-Xylan in Larch and SCMP

分析了落叶松及其磺化化机浆中阿拉伯糖基４－Ｏ－甲基葡萄糖醛酸木聚糖红外光谱，介绍了该聚糖在原料心、边材以及落叶松ＳＣＭＰ，过氧化氢漂白前后的情况。

IR spectral anlysis of aralino-4-O-methyl-glucorono-xylan in the larch and its SCMP is presented in this paper. It is shown that this xylan in the heartwood is approximately the same as that in the sapwood. The xylan content in this SCMP of larch varies also slightly befor and after H 2O 2 bleaching.
