PROCESS FOR PREPARING NITROPARAFFINS BY NITRATION IN A GASEOUS PHASE

摘要

abbreviated descriptionthe present invention relates to the production of nitroparaffins by nitration in the gas phase under pressure, if anyonly in the presence of an oxygen gas. the reagent is a nitrera mixture containing a substantial amount of propane, the temperature.the reaction temperature and pressure, the contact time, andthe quantitative relationships between the nitrant agent, mixingnitrer and oxygen gas is selected in such a way that the re -nitration action is implemented in the gas phase is homogeneous.the process allows to obtain a percentage of nitroin accordance with the "industrial and in additionthe use of less expensive raw materials at a time.
