摘要： A very pure aqueous solution of free hydroxylamine is prepared by a process in which the dilute, aqueous hydroxylamine solution is concentrated in a column by removing hydroxylamine-containing vapors via a side take-off in the bottom of the column, and very pure hydroxylamine is obtained by condensing the vapors. The novel process can be carried out simply, in a gentle manner and on a large scale and gives electronic grade hydroxylamine.

摘要： A regenerative process for the preparation of olefinically unsaturated compounds by oxidation/dehydrogenation of selectively oxidizable hydrocarbons over an oxygen carrier acting as catalyst, in the absence of molecular oxygen, alternating (in repeated cycles) with regeneration of the spent oxygen carrier with a gaseous molecular oxidizing agent, in which the spent (reduced) catalyst is cooled, prior to introduction of the regenerating gas, to a temperature which is below the temperature of the reaction, regeneration being controlled in such a manner that the highest temperature occurring during regeneration does not exceed the temperature of reaction at which dehydrogenation is commenced.

摘要： An aqueous solution of free hydroxylamine is prepared by a process in which the solution obtained by treating a hydroxylammonium salt with a base is separated into an aqueous hydroxylamine solution and a salt fraction by treatment with water or steam at .ltoreq.80.degree.0 C. The novel process can be carried out in a simple and gentle manner and on a large industrial scale. Owing to the low thermal load, the low concentration of hydroxylamine and the short residence time in the process, the risk of decomposition is minimized.
