PROCESS FOR THE PREPARATION OF C1-C4-ALKYL NITRITES

摘要

Process for the preparation of C1-C4-alkyl nitrites A b s t r a c t C1-C4-Alkyl nitrites can be prepared by reaction of C1-C4-alkanols with nitrogen oxides with the participation of oxygen in a reactor designed as a scrubber column, nitrogen oxides having a proportion of more than 50% of NO of the total amount of gram atoms of N of the nitrogen oxides, oxygen and optionally inert gas being fed into the lower part of the reactor. 5 to 60% of the total amount of C1-C4-alkanol used is likewise fed into the lower part of the reactor in vaporous or atomized form, while the remaining C1-C4-alkanol is delivered to the column head.
