Abstract

An impregnation composition for a thermochemical modification of wood comprising a balanced aqueous-alcoholic solution and having the following chemical formulation, parts by mass: water-soluble oil shale crude phenols 100 urea 28-36 formaldehyde 35-40 ammonia 13-15 ethylene glycol, its homolog or glycerol 3-10 ethanol 5-1,750 water 100-3,370. A process for preparing an impregnation composition consists in that a mixture of 100 parts by mass of said water-soluble oil-shale crude phenols, 28-36 parts by mass of urea, 3-10 parts by mass of ethylene glycol, a homolog thereof or glycerol 6-1,025 parts by mass of ethanol and 3-1,492 parts by mass of water is heated at a temperature of from 60 to 95.degree.C to give an aqueous-alcoholic solution A; a mixture of 95-107 parts by mass of a 37% aqueous solution of formaldehyde, 54-62 parts by mass of a 24% aqueous solution of ammonia, 1-725 parts by mass of ethanol and 1-1,764 parts by mass of water is maintained at 20-60.degree.C to give a solution B; solutions A and B are mixed in the mass ratio of 1:1.
