    Abstract: A process and reaction vessel for producing alkyl nitrite is disclosed, the process comprising (a) contacting nitric oxide¸ lower alcohol and oxygen in a reaction zone such that alkyl nitrite is formed, said reaction zone comprising a reactor section and a rectification section, (b) supplying a liquid scrubbing agent to an upper portion of the rectification section, (c) withdrawing a gaseous alkyl nitrite product stream from the upper portion of the rectification section, and (d) withdrawing a liquid stream from a lower portion of the reactor section. The reactor section provides intimate vapor-liquid contact sufficient to enhance the conver­sion of nitric oxide to alkyl nitrite and the rectification section provides sufficient vapor residence time to enhance conversion of oxygen, as well as sufficient rectification capabilities to reduce the amounts of water and nitric acid in the gaseous alkyl nitrite product stream.
