Abstract: An aqueous solution of a resin glue comprising formaldehyde, urea, melamine and phenol is obtained when phenol, formaldehyde and not more than 0.35 mole of an alkali metal bisulfite per mole of phenol are reacted to give a phenol-formaldehyde condensate, formaldehyde and urea in a molar ratio of not more than 2.5 are reacted to give a urea-formaldehyde condensate, and the reaction products are in turn reacted with melamine and formaldehyde.

Abstract: Diketones are prepared by oxidizing glycols in the presence of a silver catalyst and/or copper catalyst of a specific particle size, under specific temperature conditions and with a specific composition of the catalyst. The end products are starting materials for the preparation of dyes, drugs, plastics, scents, wrinkle-resist finishes and assistants for increasing the tear strength and resilience of fibrous materials, hardeners for use in the photographic industry, textile assistants for preventing shrinkage after washing, and paper assistants.

Abstract: The reaction is by dehydration of methanol over a silver catalyst. The screen, which is fastened to the base in several places carries the catalyst a small distance above the base thereby reducing the pressure drop across the catalyst bed.

Abstract: Process for the preparation of N,N-dialkylarylamines (I) by reacting arylamines (II) with alcohols (IIIa) or dialkyl ethers (IIIb) in the presence of an oxyacid of phosphorus or of an ammonium salt thereof as catalyst, characterised in that the oxyacid of phosphorus is reacted with an arylamine (IV) before the beginning of the reaction. The invention furthermore relates to the regeneration of the catalyst, by interrupting the reaction occasionally and treating the catalyst phase with steam or water at 100 to 300 DEG C.
