20.500.12556/DiRROS-7416 Etanolamin v zaščitenem lesu Ethanolamine iin impregnated wood 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. 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. zaščita lesaq etanolamin fiksacija etanolamina barvna reakcija FTIR zaščiteni les wood preservation ethanolamine spot-tests fixation of ethanolamine FTIR of impregnated wood true false true Slovenski jezik Angleški jezik Neznano 2017-07-12 09:14:23 2017-07-12 09:14:23 2022-08-12 13:45:11 0000-00-00 00:00:00 2000 0 0 str. 143-159 Vol. 61 2000 0000-00-00 Zaloznikova Objavljeno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 630 0351-3114 URN:NBN:SI:doc-EEC57KEX 686758 6206978 zbgl-61-7.pdf zbgl-61-7.pdf 1 8BE112E2A0B8140439C84D55C923DA67 c44a4d1a7ea8eb9f7d16425ae757b20b32c21b03443200c582bea3dbc69ac4ab 0da8b488-17b5-11ed-b6b8-001a4af901a5 20.500.12556/dirros/52d9d0a4-1b08-4996-ba11-40f67c3b7311 https://dirros.openscience.si/Dokument.php?lang=slv&id=9266 Gozdarski inštitut Slovenije Acta Silvae et Ligni 0 0 0
