USE OF ALKOXYLATED AMINES TO IMPROVE WATER-REPELLENT PROPERTIES Russian patent published in 2011 - IPC B27K3/36 B05D7/06 B27K5/06 

FIELD: chemistry.

SUBSTANCE: invention relates to use of alkoxylated amines to treat wood in order to improve water-repellent properties of wood or reduce the amount of water absorbed by wood. Treatment is carried out with alkoxylated amines of formula where R¹ denotes C_8-20-alkyl; R² denotes -[CH₂CH(X)O]_bH (a-1) or n is an integer from 1 to 4; each of a, b and c independently denotes an integer ranging from 1 to 20; each X is independently selected from a group comprising hydrogen, methyl, ethyl and phenyl. Alkoxylated amines of formula (I), particularly N,N',N' -tris(2-hydroxyethyl)-N-cocoalkyl-1,3-diaminopropane or N,N',N'-tris(2-hydroxyethyl)-N-tall alkyl-1,3-diaminopropane can be used in the composition for treating wood in amount of 0.1-90 wt %.

EFFECT: use of alkoxylated amines of formula (I) to treat wood improves water-repellent properties of wood and reduces the amount of water absorbed by wood.
