    Abstract: PROBLEM TO BE SOLVED: To provide a method for efficiently producing an alkyl nitrite in higher yield by reaction between nitrogen dioxide and an alkanol. SOLUTION: The method for producing the alkyl nitrite comprises feeding a reaction column with the alkanol and water to allow them to flow down and countercurrently contacting them with the nitrogen oxide while feeding it into the reaction column. More specifically, this method comprises the step (1) of introducing bottoms extracted from the bottom of the reaction column into a reactor, into which carbon monoxide or hydrogen is fed in the presence of a platinum metal catalyst and both the alkanol and nitric acid in the bottoms are reacted with the carbon monoxide or hydrogen to form the alkyl nitrite and the step (2) of feeding the alkyl nitrite into the zone where the alkanol in the reaction column is flowing down.

    Abstract: PROBLEM TO BE SOLVED: To provide an industrially preferable method for preparing an alkyl nitrite which is capable of preparing the alkyl nitrite easily and at a low cosy with a high efficiency. SOLUTION: The method for preparing the alkyl nitrite is characterized by reacting nitric acid and an alkanol, in the presence of a platinum group metal catalyst, with carbon monoxide or hydrogen. Further, a method for preparing the alkyl nitrite is characterized by using an aqueous solution containing nitric acid wherein the concentration of nitric acid is not higher than 60% by weight and contains 5 to 70% by weight of an alkanol, in the presence of the solid catalyst in which the platinum group metal or its compound is supported on the carrier, and the reaction is conducted until the concentration of nitric acid reaches not higher than 1% by weight.
