Hardening by Autocondensation of Tannins the autocondensation reactions characteristic of polyflavonoid tannins have only recently been used to prepare adhesive polycondensates hardening in the absence of aldehydes [70] allergy symptoms to kiwi fruit generic 5 mg prednisone with amex. Although this reaction may lead to considerable increases in viscosity allergy medicine xy purchase prednisone 20mg, gelling does not generally occur allergy medicine restless leg syndrome cheap prednisone online amex. In the case of the more reactive procyanidin and prodelphinidin type tannins allergy forecast okc discount 10 mg prednisone with amex, such as pine tannin, cellulose catalysis is more than enough to cause hardening and to produce boards of strength satisfying the relevant standards for interior-grade panels [74]. In the case of the less reactive tannins, such as mimosa and quebracho, the presence of a dissolved silica or silicate catalyst of some type is essential to achieve panel strength as required by the relevant standards. The classical method of this type still used is the hide-power and derived methods. These methods were devised to determine which percentage of the extract would participate in leather tanning. The main drawback for their use for adhesives in their inability to detect and determine the approximate 3 to 6% of monoflavonoids and biflavonoids, or phenolic ``nontannins,' present in the extract which do not contribute to tanning capacity but which do definitely react with formaldehyde and contribute to adhesive preparation. Methods aimed at the determination of phenolic material present in the extract that can be reacted with formaldehyde. These methods were devised particularly for tanning extracts used in adhesives and are all based on the determination of some of the products of reaction of the flavonoids with formaldehyde. Accepted methods of the first type comprise the hide-power method [77], the refractometric method, and various visible, ultraviolet, and infrared spectrometric methods. Janiga, Masonite and lignosulphonate resins, Wood Adhesives 2000, Tahoe, Nevada, June 2000. On the other hand, technical utilization of lignin on a large scale is still at a very low level for the amount produced worldwide. Only about 20% is used for various purposes, such as dispersants, oil-well-drilling muds, pelletizing materials, molding stabilizers, and concrete grinding additives. As a major wood component, native lignin is neither hygroscopic nor soluble in water. Cross-linking in lignin can be achieved either by condensation or by radical coupling reactions. However, either high temperatures and long heating times or mineral acids are required for these condensation reactions, which cause structural changes or charring in the wood particles. Recently, cross-linking of the lignosulfonate molecules by radical combinations, which avoids mineral acids and high temperatures, has been developed, but this presents disadvantages as well, since the use of peroxides is not favored in wood processing plants, for a variety of reasons. The use of lignin by polycondensation reactions with formaldehyde also presents the disadvantage of slower pressing time in their application to panel products. The unpaired electron in R is delocalized and reacts at three different sites of the radical, indicated by four resonance structures, leading to dilignols. Cross-Linking by Condensation Reactions When lignosulfonate is treated with strong mineral acids at elevated temperatures or heated at temperatures above 180 C, condensation reactions leading to diphenylmethanes and sulfones take place. Of the four lignosulfonates obtained technically, the calcium-based exhibit the lowest and the ammonium-based the highest reactivity; the sodium and magnesium lignosulfonates show a medium reactivity. Hydrobenzyl alcohol groups as well as sulfonic acid groups on the carbon a to the aromatic rings of some of the phenylpropane units of the random polymer react in the presence of strong mineral acids with the aromatic nuclei of other phenylpropane units. This reaction, leading to diphenylmethanes, is of the same type as the formation of phenolic resins from phenol and formaldehyde. Lignin also reacts with formaldehyde and can be cross-linked by it in the same manner as that of synthetic polyphenolic resins.
