direct gas phase nitration of low carbon alkanes is mainly used in industrial production. With ethane as raw material, can be nitromethane and nitroethane two products, with propane as raw material, can be prepared nitromethane, nitroethane and 1-and 2-nitropropane four products. Using ethane and propane as raw materials for nitration can change the reaction conditions to change the product ratio.
used as solvents, pharmaceutical intermediates, explosives, rocket fuels and analytical chemical reagents.
