PREPARACION DE ESTERES DE NITRITO

摘要

The invention deals with the preparation of methyl or ethyl nitrite from the corresponding alcohols in a vapor phase process.
A molar amount of nitrogen oxide composition containing a nitric oxide to nitrogen dioxide molar ratio of greater than 1 is reacted in a vapor state in a reactor (76) with a molar amount of vaporized methanol or ethanol wherein the molar ratio of methanol or ethanol to the combined molar amount of nitric oxide and nitrogen dioxide is greater than 1, at a temperature of 10 DEG C to 300 DEG C in the presence of an inert gaseous diluent.
This process may be run at relatively low temperature and pressure while minimizing the formation of by-products.
