Abstract:Zaščita lesa je, kljub poostrenim okoljevarstvenim zahtevam, še vedno nujno potrebna in ekonomsko upravičena. Zaradi dobrih fungicidnih lastnosti se za impregnacijo lesa množično uporablja tudi bakrove spojine. Ker se dokaj slabo vežejo v les, se iz njega izpirajo. V kombinaciji s kromom pa se baker v lesu dobro fiksira. V zadnjem času so v mnogih državah omejili uporabo kromovih soli, oziroma jih nameravajo prepovedati. Strokovnjaki zato za fiksacijo bakra iščejo druge spojine. Kot primerni in potencialno uporabni so se izkazaliamini. Raziskovali smo interakcije med bakrovimi pripravki z etanolaminom (C2H7NO, 2-aminoetanol) in komponentami lesa. Opazili smo, da etanolamin z lesom reagira. Z metodo nihajne spektroskopije (FTIR) smo opazilispremembe na skupinah lignina in polioz. Razvili smo tudi metodo, kjer reagent z barvno reakcijo dokaže prisotnost etanolamina v lesu.

Title:Ethanolamine iin impregnated wood
Abstract:Wood preservation is necessary and is economically important. Copper compoundsare used for wood preservation because of their good fungicidal properties. Since copper compounds do not fix into wood, they can leach out of it. A presence of chromium prevents leaching of copper from wood. Recently, many countries intend to bound or limit the use of chromium salts. Therefore, experts looking for other suitable compounds to fix copper and amines seem to be suitable substitutes for chromium. We report about our investigations of interactions between copper(II) octanoate and ethanolamine (C2H7NO, 2-aminoethanole) and wood or its components. We found out that ethanolamine chemically reacts with wood. With the FTIR method, we noticed changes on groups belonging to lignin or hemicelluloses. We developed an indicator for spot-tests spot-tests of ethanolamine in wood.
Keywords:wood preservation, ethanolamine, spot-tests, fixation of ethanolamine, FTIR of impregnated wood
