Abstract: Method of treating wood products to improve fire resistance thereof. The method comprises treating wet wood objects with compositions comprising an aqueous solution of bisphosphonate selected from 1-hydroxyethane 1,1-diphosphonic acid, an alkanol amine, and optionally an alkaline agent, the composition having a pH in the range of 4.0 to 7.0 to impregnate the object with the compositions, and subjecting the object so obtained to drying to achieve aspiration of the pits of the wood object. The method can be used for protecting wood not only against fire but also against mould, rot, blue stain, insect such as termite attacks on wood, dimensional changes, or a combination thereof due to environmental influence.

Abstract: Fire retardant composition for treatment of various wood products, method of producing the same and uses thereof. The compositions comprise an aqueous solution of bisphosphonate selected from 1-hydroxyethane 1,1-diphosphonic acid, an alkanol amine, and optionally an alkaline agent, the composition having a pH in the range of 4.0 to 7.0. The composition can be produced by mixing together 30 to 50 parts by weight of 1-hydroxyethane 1,1-diphosphonic acid; 1 to 10 parts by weight of an alkanol amine or mixture thereof, said alkanol amine being added in free form; and optionally 0.1 to 40 part by weight of an alkaline agent; and water. The compositions can be used for protecting wood not only against fire but also against mould, rot, blue stain, insect such as termite attacks on wood, dimensional changes, or a combination thereof due to environmental influence.

Abstract: A method for preparing a composition with low corrosive effect and low freezing point including mixing an ammonium cation source with a carboxyl anion source in an appropriate molar or weight ratio for obtaining an organic ammonium carboxylate of formula [NR1R2R3R4]+n [R5(COO)n]?n in which R1, R2, and R3 are selected from the group comprising hydrogen, substituted and unsubstituted alkyls containing 1-6 carbon atoms, R4 is a substituted or unsubstituted alkyl containing 1-6 carbon atoms, R5 is hydrogen, a substituted or unsubstituted hydrocarbon containing 1-6 carbon atoms and n is an integral of 1-6, and thereafter adding possible solvent and at the same time keeping alkali or alkali-earth metal content of the composition in a range of 0.001-30 wt % and halide content in a range of 0.001-1 wt %.

Abstract: The invention relates to a catalytic process for reducing nitrogen oxides in flue gases, in which process a reducing agent containing composition is mixed with flue gas and the mixture achieved is brought into contact with a catalyst. In accordance with the invention, the composition contains e.g. 1 to 60% of weight of ammonium formate. Especially a low freezing point can be achieved with such water containing composition. In addition, a good reduction conversion is achieved even at low temperatures.
