Description

Technical field [0001] The invention belongs to the technical field of production of nitrate esters of petrochemical products, and particularly relates to a device for continuous production of isooctyl nitrate. Background technique [0002] Nitrate esters are an important class of organic compounds, which are widely used in modern scientific fields such as aerospace, military applications, medicine and health, petroleum processing, dyes and pesticides. As an important nitrate compound, isooctyl nitrate is mainly used as a diesel fuel additive to increase the cetane number of diesel, thereby improving the combustion performance and safety of diesel, and reducing the pollution of combustion exhaust gas to the atmosphere. It is generally accepted Cetane number improver. The traditional production process of isooctyl nitrate mainly adopts the mixed acid method. This method is mostly carried out in a conventional tank reactor, the reaction process is not easy to control, the exother...
