Abstract: Nitrous ester is prepd. in vapor phase reaction. Nitrous ester is a colorless liquid, which is useful as a stabilizer for vinyl compd., a chemical for synthesis and a spasmolytic. Nitrogen oxide composition whose NO/NO2 molar ratio is more than one is evaporated, and then the evaporated nitrogen oxide composition is reacted with evaporated methanol (or ethanol) to give methyl nitrite(or ethyl nitrite). This reaction is performed in a diluent gas, such as nitrogen or carbon dioxide.

Abstract: The invention deals with the preparation of nitrite esters in vapor phase from nitrogen oxide, alcohol and an inert diluent. The reaction, which occurs between 50 and 140 DEG C at or above atmospheric pressure, takes place into a first reaction zone optimizing the reaction N2O3 + ROH -> RONO + HONO and a second reaction zone optimizing the reaction ROH + HONO -> RONO + H2O. The formation of acid by-products is minimized as compared to a unitary reaction zone.
