ABSTRACT:
C.sub.1 -C.sub.6 -Alkyl nitrites can be prepared by reacting nitrogen dioxide with C.sub.1 -C.sub.6 -alcohols, by, in a counterflow-operated column, feeding the alcohol or an alcohol/water mixture into the upper part of the column and the nitrogen dioxide or a nitrogen dioxide/inert gas mixture into the lower part of the column. The resulting alkyl nitrite is removed from the column as the top product and the co-formed nitric acid is removed from the column as the bottom product.
