Sulfidation is a process of installing sulfide ions in a material or molecule. The process is widely used to convert oxides to sulfides but is also related to corrosion and surface modification. ==Inorganic, materials, and organic chemistry== Sulfidation is relevant to the formation of sulfide minerals.〔Sillitoe, Richard H. "Porphyry copper systems" Economic Geology (2010), 105(1), 3-41. 〕 A large scale application of sulfidation is the conversion of molybdenum oxides to the corresponding sulfides. This conversion is a step in the preparation of catalysts for hydrodesulfurization wherein alumina impregnated with molybdate salts are converted to molybdenum disulfide by the action of hydrogen sulfide. In organosulfur chemistry, sulfiding is often called thiation. The preparation of thioamides from amides involves thiation. A typical reagent is phosphorus pentasulfide (P4S10). The idealized equation for this conversion is: :RC(O)NH2 + 1/4 P4S10 → RC(S)NH2 + 1/4 P4S6O4 The process involves no redox reaction. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Sulfidation」の詳細全文を読む スポンサード リンク
