Abstract: A process for producing formaldehyde by oxidizing dehydrogenation of methanol in the presence of a silver catalyst, wherein a vaporous mixture of water and oxygen is introduced into the vaporous starting mixture containing water, methanol and oxygen before entry into the catalyst bed. Formaldehyde produced by the process is a disinfectant, tanning agent, reducing agent and raw material for the production of synthetic resins, adhesives and plastics.

Abstract: Aq. amino resins (I) contg. 60-75 wt.% solids are claimed; (I) are obtd. by heating a mixt. of (A) 60-98 wt.% aq. UF precondensate and (B) 2-40 wt.% M/UF precondensate for 10-45 mins. at 70-100 deg.C and pH 7.5-9; (A) is derived from (a1) 30-50 mol.% urea, (a2) 50-70 mol.% formaldehyde (F) and (a3) 0-2 mol.% other condensable components, and (B) is derived from (b1) 15-35 wt.% melamine, (b2) 10-15 mol.% urea, (b3) 55-70 mol.% (F) and (b4) 0-2 mol.% other condensable components; the theoretical mol. ratio (F):(amino gps. in I) is (0.45-0.6):1, and this condition is fulfilled if necessary by addn. of urea after heating (A) and (B). - 2. The above process is claimed as such.
