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: The production of combustion gas containing little or no carbon black by mixing a starting mixture of oxygen and methanol with more oxygen in specific proportions, igniting the mixture thus prepared and incompletely burning the methanol in the flame formed. The gas may be used advantageously in all cases where deposition of soot would be troublesome. It may be used with advantage for heating catalysts in catalytic syntheses, for example silver catalysts to be used for catalyzing the reaction of methanol with oxygen to form formaldehyde.
Abstract translation: 通过将氧和甲醇的起始混合物与特定比例的更多的氧混合，生产含有很少或不含炭黑的燃烧气体，点燃由此制备的混合物，并在形成的火焰中不完全燃烧甲醇。 在烟灰沉积麻烦的所有情况下，可以有利地使用气体。 它可以有利地用于在催化合成中加热催化剂，例如用于催化甲醇与氧气反应形成甲醛的银催化剂。

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of a silver catalyst and of certain amounts of steam and formaldehyde, some formaldehyde and a part of the water being withdrawn from the reaction mixture and recycled.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.

Abstract: 1480921 Stabilizing aqueous formaldehyde BASF AG 25 Nov 1974 [26 Nov 1973] 50896/74 Heading C2C Aqueous formaldehyde solutions are stabilized by means of a bis-guanamine of formula wherein the two substituent on the phenylene ring are in m or p-position to each other. 0À001 to 0À5% by weight of stabilizer may be used and the formaldehyde solution may contain 28-65% by weight of formaldehyde. The stabilizer may be added as a stock solution in a formaldehyde solution of higher strength than that to be stabilized and having a pH of 2À5 to 5À8 and the latter is preferably kept at 40-80‹ C. for 10-30 hours before adding the stock solution.
