The role of crystalline structure of molybdenum oxide catalysts onto the activity and stability in sulfoxidation of thioethers
Sulfoxidation of 2-thiomethyl-4,6-dimethyl-pyrimidine and methyl-dodecyl-sulfure was carried out in liquid phase using H 2O 2 in dioxane (6 or 18 wt%) and several molybdenum and mixed antimony–molybdenum oxides such as: Mo 8O 23, MoO 3-basal, MoO 3-iso, Sb 2MoO 6 and a mixture of Sb 2Mo 10O 31 and S...
