PENTOSANS IN WOOOD AND PULP
Wood, Pulp, Pentosans, Hemicellulose

Product Details
- 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.
