Abstract: The invention discloses a method for the continuous preparation of n-butyl nitrite with a low content of n-butanol comprising the reaction of n-butanol, an acid and NaNO2 in a continuous way, in which the n-butanol, an acid and NaNO2 are mixed in a mixing device which provides for a pressure drop of at least 1 bar; the acid is selected from the group consisting of HCI, H2SO4, formic acid, methanesulfonic acid, and mixtures thereof; and the amount of HCI is at least 1.02 molar equivalent based on the molar amount of n-butanol.

Abstract: The invention relates to a continuous method for producing alkyl nitrites and alkyl dinitrites. According to said method, (i) an alkanol or dialkanol is mixed with an aqueous solution of a mineral acid, whereby on average no more than 1.01 mol acid equivalents per mol hydroxyl group of alkanol or dialkanol is used, (ii) in a reaction zone, an aqueous solution of an inorganic nitrite is continuously added to the aqueous mixture obtained in step (i), (iii) the organic phase is optionally isolated.

Abstract: An alkyl nitrite can be produced on an industrial scale with a high efficiency and with a low yield of by-products by the process wherein nitrogen oxide-containing feed gas is brought into an alkyl alcohol liquid in a distillation column reactor while circulating a liquid fraction, produced in the reactor and containing the alkyl alcohol, through a circulation path including a lower section of the reactor and a cooler to remove the reaction heat vigorously generated in the reactor, and while controlling the weight ratio of the circulating liquid fraction to the total alkyl alcohol fed into the reactor to 50:1 to 200:1, the molar ratio of the total alkyl alcohol fed to the reactor and contained in the circulating liquid fraction to nitrogen oxide in the feed gas to 20:1 to 150:1, and the content of the alkyl alcohol in the liquid fraction to 15 to 60% by weight; and the resultant gas fraction containing the target alkyl nitrite is collected from the reactor.

Abstract: C₁-C₄-Alkyl-nitrite können durch Umsetzung von C₁-C₄-Alkanolen mit Stickstoffoxiden ohne Beteiligung von Sauerstoff in einem als Wäscherkolonne ausgebildeten Reaktor hergestellt werden, wobei als Stickstoffoxid Distickstofftrioxid im unteren Teil des Reaktors eingesetzt wird, und zwar a) als solches, b) als Gemisch mit Stickstoffmonoxid oder c) als Gemisch seiner Vorläufer Stickstoffmonoxid/Stickstoffdioxid bzw. Stickstoffmonoxid/Distickstofftetroxid. Das C₁-C₄-Alkanol wird zu 5 bis 60 % seiner gesamten Einsatzmenge ebenfalls im unteren Teil des Reaktors in dampfförmiger oder verdüster Form eingesetzt, während das restliche C₁-C₄-Alkanol auf den Kolonnenkopf gegeben wird.
