Abstract: A process for the production of an alkali-condensed phenol-urea-formaldehyde (PUF) resin with a mol ratio of P:F:U = 1:(1.5-3.5):(0.3-2.5), comprising (a) preparation of a PF condensate by reacting phenol (P) with 60-90% of the total amount of formaldehyde (F) to be used, and (b) reaction of this PF condensate with the remaining 10-40% F and the urea. Also claimed is PUF resin obtained by this process.

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.

Abstract: The present invention relates to agents containing a polyamine, a sugar and one or more components from the group formed from dicarboxylic acid derivatives, aldehydes having two or more carbon atoms and epoxides. The invention furthermore relates to the use of such agents for the preparation of binders for gluing wood.

Abstract: Formaldehyde is manufactured by oxidative dehydrogenation of methanol in the presence of a silver catalyst and of certain amounts of steam and formaldehyde, some formaldehyde and a part of the water being withdrawn from the reaction mixture and recycled. The formaldehyde manufactured by the process may be used as a disinfectant, tanning agent, reducing agent and starting material for the manufacture of synthetic resin, adhesives and plastics.
