Environmentally Friendly Wood Preservative System Based on Polymerized Tannin Resin-boric Acid for Outdoor Applications♣
Boron compounds are used as wood preservatives as they are both fungicide and insecticide, relatively inexpensive and environmentally acceptable. Nevertheless, in the field of wood protection, borates are only used for indoor non-exposed applications or in association with other biocides, due to their main disadvantage of being readily leachable from treated wood. To overcome this problem, bori...

This article reviews the various aspects of tannin, which is finding varied uses in leather industry and pharmaceutics.
متن کاملSystematic studies of tannin–formaldehyde aerogels: preparation and properties
Gelation of tannin-formaldehyde (TF) solutions was systematically investigated by changing pH and concentration of TF resin in water. In this way we constructed the TF phase diagram, from which chemical hydrogels could be described, and also synthesized thermoreversible tannin-based hydrogels. Conditions of non-gelation were also determined. Hydrogels were dried in supercritical CO2, leading to...
متن کاملOrigin of Oak - Bark Tannin
DRUGS AND UPTAKE OF 32p BY ERYTHROCYTES 533' 5. Sodium salicylate and sodium thiopentone depressed the 32p uptake of 2:3-diphosphoglycerate and adenosine triphosphate to a greater extent than they depressed the 32P exchange of inorganic phosphate and hexose monophosphate. These agents do not depress 32p uptake by inhibiting triose phosphate dehydrogenase, for neither drug had any effect on glyc...
متن کاملVariability in tannin content, chemistry and activity in a diverse group of tannin containing sorghum cultivars.
BACKGROUND Tannins are large polyphenolic polymers and are known to bind proteins, limiting their digestibility, but are also excellent antioxidants. Numerous studies investigating the functional properties of sorghum tannin have been conducted by comparing grain samples from different sorghum lines without considering the other intrinsic characteristics of the grain. The purpose of this study ...
