Preparation of Dissolving Pulp Made from Poplar Residual Slabs and Effect of Xylanase Post-treatment on Its Reactivity

BioResources, 2014
The production of dissolving pulp from poplar wood residual slabs was investigated. The residual slab chips were initially prehydrolyzed and subsequently pulped by the kraft process; the resulting brownstock was bleached using a totally chlorine-free ...

Hemicelluloses in Dissolving Pulps

The Journal of the Society of Chemical Industry, Japan, 1960
溶解用パルプ中の非グルコース成分,ウロン酸などを定量し,原木および蒸解法との関係を明らかにしようと試みた。マンノース基は広葉樹パルプに少なく,針葉樹パルプ,特にアメリカ産パルプに多い。ウロン酸と原木,蒸解法との関係は認められなかった。適当なマンノース基/グルコース基を仮定して,マンノース基量よりグルコマンナン量を計算し,キシラン量と合わせて全ヘミセルロース量を求めたが,これはγ-セルロースと比例関係がある。溶解用パルプ中のヘミセルロースも,フェーリング液によりグルコマンナンとキシランにほぼわけることができる。亜硫酸法および硫酸塩法パルプのα-,β-,γ-セルロースの組成を比較検討した。
