Vapor Phase Nitration of o-Xylene Process by kanashibiotech is a document available to read on EtoBox.

The patent US 6,825,388 B2 describes a process for the vapor phase nitration of o-Xylene to produce 4-nitro-o-Xylene using dilute nitric acid over H-beta Zeolite catalyst. This method aims to improve yield and selectivity while being environmentally friendly by avoiding the use of sulfuric acid. The process operates under specific conditions, including a temperature range of 100-250°C and a molar ratio of nitric acid to o-Xylene between 2:1 and 1:2.
