Dissolving-Grade Pulp Compositions |
| 摘要 |
Dissolving-grade pulp compositions are prepared by treating a cellulosic material with an extractant comprising a cellulose solvent and co-solvent. The dissolving-grade pulp compositions comprise at least 90 wt. % glucan, from 0.6 to 5 wt. % xylan, and have distinct molecular weights, and elemental metal ions from known and commercially available dissolving-grade pulp compositions. |
