Abstract: PROCESS FOR SEPARATING TRIETHANOLAMINE CONTINUOUSLY BY DISTILLATION FROM A MIXTURE OF MONOETHANOLAMINE, DIETHANOLAMINE AND TRIETHANOLAMINE TOGETHER WITH ETHANOLAMINE ETHERS AND WATER OBTAINED BY REACTION OF AMMONIA WITH ETHYLENE OXIDE IN THE LIQUID PHASE UNDER SUPERATMOSPHERIC PRESSURE AND AT ELEVATED TEMPERATURE, IN WHICH THE MIXTURE IS DISTILLED IN TWO STAGES. THE LOW-BOILING FRACTION AND THE HIGH-BOILING FRACTION ARE TAKEN OFF AND DISCHARGED IN THE FIRST STAGE AND THE INTERMEDIATE-BOILING FRACTION COMPRISING > 99.4% BY WEIGHT OF TRIETHANOLAMINE AND

Abstract: The invention concerns a process for preparing aqueous aminoplastic resins which are suitable as binders for producing derived timber products. The process is characterized in that: a) 1 mole melamine; b) a concentrated aqueous solution of 0.5 to 5 moles urea and 3 to 6 moles formaldehyde per mole of urea, in which urea and formaldehyde can also be present in the form of their reaction products, c) 0.01 to 0.5 moles phenol or a phenol derivative which can be polycondensed, d) 0 to 9 moles formaldehyde, and e) 0 to 1 mole of a further compound which can be polycondensed are reacted with one another at 50 to 100 DEG C and a pH of 7.5 to 10.0 until the solution attains a viscosity of 10 to 1500 mPa.s, after which this solution is left to cool, and f) is mixed with 0.55 to 0.75 moles urea per mole of the total amount of urea used as components (b) and (f).

Abstract: Disclosed are aqueous binder mixtures suitable for producing derived timber products and containing (A) an aqueous aminoplast resin consisting of (a1) melamine, (a2) 0.8 to 6 mol urea per mol melamine, (a3) 2 to 20 mol formaldehyde per mol melamine and (a4) 0 to 1 mol of another compound that can react with formaldehyde in an addition reaction or condensation reaction and is different from phenol or a condensation-polymerizable phenol derivative, per mol melamine, and (B) 0.55 to 0.75 mol urea per mol of the total amount of urea used as components (a2) and (B), with the proviso that the molar ratio of the melamine (component (a1)) to the total amount of urea (components (a2) and (B)) is 1:3.5 to 1:13 and that the molar ratio of formaldehyde (component (a3)) to the -NH2 groups in components (a1), (a2) and (B) is 0.2:1 to 0.7:1.
