The invention relates to a method for producing modified lignocellulosic materials. Said method consists of the following steps a) the lignocellulosic material is impregnated with an aqueous composition which contains i) at least one cross-linkable nitrogen compound and ii) at least one substance which catalyses the cross-linking, b) the impregnated lignocellulosic materials are treated at higher temperatures in order to remove the water and to cross-link the cross-linkable nitrogen compound. In step b) the impregnated lignocellulosic material is treated with overheated steam. The invention also relates to lignocellulosic materials which are obtained according to said method.

The invention relates to a method for impregnating lignocellulosic materials, in particular, wood, wood materials or materials for manufacturing wood materials, with effect agents. The invention also relates to novel compositions, containing effect agents. Said method comprises the steps of a) impregnating the lignocellulosic material with a fluid formulation, which contains at least one effect agent in a dissolved or dispersed form, b) impregnating said material, during or after step a), with a hardenable aqueous composition, which contains at least one cross-linkable compound, selected from &agr;) low-molecular weight compounds V, having at least two N-bonded groups of formula CH2OH, wherein R=hydrogen or C1-C4 alkyl, and/or one 1,2-bishydroxyethan-1,2-diyl group, bridging two nitrogen atoms, &bgr;) precondensates of the compound V and ϝ) reaction products or mixtures of the compound V with at least one alcohol, selected from C1-C6 alkanols, C2-C6 polyols and oligoalkylene glycols, and c) treating the material obtained in step b) at an elevated temperature.
摘要:
Glyceric acid compounds of the formula (I) R1R2C(OH)—CR3(OH)—COOX (I) where R1, R2 and R3 are independently hydrogen, C1-12-alkyl, C6-12-aryl, C7-13-alkaryl or C7-13-aralkyl and X is hydrogen, an alkali metal, an alkaline earth metal/2 or NH4, are prepared by saponification of glycidic acid compounds of the formula (II) where Y is NH2 or OR4 in which R4 is C1-12-alkyl or C7-13-aralkyl, with ring-opening addition of water onto the epoxide ring. Preferably, Y is NH2 and the glycidamide of the formula (II) which is used is prepared by reacting acrylonitriles of the formula (III) R1R2C═CR3CN (III) with hydrogen peroxide.
