PENTOSANS IN WOOOD AND PULP

• Determination of pentosan content can be applied to both wood and to unbleached or bleached Pulps.
• Pentosans are transformed in boiling 3.85 n hydrochloric acid to furfural, which is collected in the distillate.
• Determined colorimetrically with orcinol-ferric chloride reagent.
• Wood contains a certain amount of noncellulosic carbohydrates called hemicelluloses.
• Pentosan content in softwoods is about 7 to 10%, and in hardwoods about 19 to 25%.
• Pentosan content in pulp indicates the retention or loss of hemicelluloses in general during pulping and bleaching processes.
