An investigation of the effect of dihydroquercetin and quercetin on bleaching of Douglas-fir groundwood

Creator:: Meng, Tommy Yi
Abstract:: Sapwood and heartwood groundwood samples were prepared separately from a second growth, coastal range, young Douglas-fir (Pseudotsuga menziesii (Mirb.) Franco). The bleaching responses of these two groundwoods to zinc hydrosulfite were examined, and the roles of both dihydroquercetin and quercetin in this bleaching reaction were investigated. Heartwood groundwood was identified...

Molecular weight distribution analysis of wood pulp cellulose by size exclusion chromatography

Creator:: Silva, Arlene Avenido
Abstract:: Automated size exclusion chromatography with a differential refractometer detector was employed to study the molecular weight distribution patterns in various types of wood pulp cellulose. The results obtained were correlated with the conventional methods of measuring these properties. The dissolution of pulp celluloses in N,N-dimethylacetamide-lithium chloride solvent was optimized. This...

Foam separation of organic and toxic materials in kraft mill effluents

Creator:: Blazier, James Lewis
Abstract:: Because of the organic nature and the natural foaming characteristics of kraft mill effluents, it was decided to investigate the feasibility of using foam separation as a method of treatment. The treatment efficiency was evaluated by BOD and COD reductions as well as the decrease in toxicity to marine life....

Improving the durability of second growth timbers of naturally durable species

Creator:: Cabrera Orozco, Yohanna
Abstract:: While the heartwood of many wood species exhibits excellent resistance to fungal and insect attack, this resistance is sometimes diminished in second-growth material of the same species. The reasons for the reduced durability are unclear, but they may reflect a combination of both higher proportions of sapwood as well as...

Bark chemicals from Shasta red fir as stiffening agents for corrugating medium

Creator:: Oregon Forest Research Center
Abstract:: In these tests, phenolic constituents from bark of Shasta red fir were found ineffective as stiffening agents for corrugating medium. Other means of application, however, may be effective. Gum from inner bark of Shasta red fir was not so effective as a beater additive as was locust bean gum, but...
