Soda–anthraquinone, kraft and organosolv pulping of holm oak trimmings
Bioresource Technology, 2006The operating conditions for an organosolv (ethyleneglycol) and two alkaline (soda-anthraquinone and kraft) processes for obtaining cellulose pulp and paper from holm oak (Quercus ilex) wood trimmings were optimized. A range of variation for each process variable (viz.

Summary Polyhydric alcohol pulping was developed to separate components of low-quality softwoods that are produced by thinning and improvement cutting as well as to establish a self-supporting pulping system. Propylene glycol (PG) was superior to ethylene glycol (EG) as solvent for polyhydric alcohol pulping at atmospheric pressure.

Organosolv delignification of southern pine – an alternative pulping process
Chemical Engineering & Technology, 1988AbstractAqueous ethylenediamine‐ethanol‐anthraquinone (EDA‐EtOH‐AQ) pulping of Southern Yellow Pine was studied for lignin removal and pulp yield. Temperature, time and ethylenediamine concentration in the solvent solution were studied and equations for lignin content and lignin‐free yield were developed.

The Properties of Organosolv Pulp and Cellulose from Eucalyptus with MK2
Advanced Materials Research, 2011In order to decline the energy consumption in pulping process and keep the crystallinity of the cellulose in pulp, eucalyptus was selected in this study. Different quantities of ethanol, formic acid and MK2 and different experimental conditions led to different contents of alpha -cellulose and different crystallinities of the cellulose.
