Standard Test Method for Dichloromethane-Soluble Matter in Cellulose

Importancia y uso:

4.1 Dichloromethane-soluble materials are typically referred to as extractives. These extractives are comprised of organic materials that originated in the wood or cotton. The measure is an indication of the efficiency of removal of these substances during pulping and bleaching. The extractive level is of concern to dissolving pulp users since the presence of large amounts of extractives could inhibit the processing of cellulose into the desired derivative.
