Title
Methane oxidation to methyl bisulfate in oleum at ambient pressure in the presence of iodine as a catalyst
Abstract

Methane oxidation to methyl bisulfate at ambient pressure in absorption reactor packed with glass balls in presence of iodine as a catalyst was investigated. The process was performed at temperature 120–130 °C, sulfur trioxide concentration in oleum 16–25 wt.%, catalyst concentration 0.008–0.024 mol dm−3, methane flow: 8.69 cm3 min−1. The optimal conditions for high ester concentration were defined.
