Procedure: To a 100 ml round bottom flask was sequentially added 10 mmol (1.54 g) of silver nitrite (AgNO2) and 20 ml of acetonitrile, followed by stirring at room temperature for 5 minutes. Next, 10 mmol (0.90 g, 1.08 ml) of diethylthioether was dropwise added to the flask by means of a syringe over 10 seconds and stirred at room temperature. After stirring for 30 minutes, the reaction mixture was warmed to 50° C. and further stirred for 30 minutes. Following cooling to room temperature, the reaction mixture was filtered through a microfilter and evaporated under vacuum to produce a pale yellow solid matter. 1H-NMR result in CD3CN is as follows: 1.31 (t, 7.34 Hz, 6H), 2.72 (broad q, 7.35 Hz, 4H). To a 100 ml round bottom flask was sequentially added stirred at room temperature After stirring for 30 minutes the reaction mixture was warmed to 50° C. further stirred for 30 minutes Following cooling to room temperature the reaction mixture was filtered through a microfilter evaporated under vacuum to produce a pale yellow solid matter 1H-NMR result in CD3CN

Procedure: To a 100 ml round bottom flask was sequentially added 10 mmol (1.69 g) of silver nitrate and 20 ml of acetonitrile, followed by stirring at room temperature for 5 minutes. Next, 10 mmol (0.90 g, 1.08 ml) of diethylthioether was dropwise added to the flask by means of a syringe over 10 seconds and stirred at room temperature. After stirring for 30 minutes, the reaction mixture was warmed to 50° C. and further stirred for 30 minutes. Following cooling to room temperature, the reaction mixture was filtered through a microfilter and evaporated under vacuum to produce a pale ivory solid matter. 1H-NMR result in CD3CN is as follows: 1.34 (t, 7.36 Hz, 6H), 2.76(q, 7.36 Hz, 4H). To a 100 ml round bottom flask was sequentially added stirred at room temperature After stirring for 30 minutes the reaction mixture was warmed to 50° C. further stirred for 30 minutes Following cooling to room temperature the reaction mixture was filtered through a microfilter evaporated under vacuum to produce a pale ivory solid matter 1H-NMR result in CD3CN

Procedure: To produce a sulfide, the sulfur compound reactant stream 10b can be a mercaptan, such as methanethiol (methyl mercaptan) or ethanethiol (ethyl mercaptan). Either one of these mercaptans can be reacted with methanol or ethanol as the alcohol feed stream 8b to produce 2-thiopropane (dimethyl sulfide), 1-(methylthio)ethane (methyl ethyl sulfide), or 1,1′-thiobisethane (diethyl sulfide), depending upon the selected sulfur compound reactant stream 10b and alcohol feed stream 8b. For example, methanethiol (methyl mercaptan) can be reacted with methanol, in the presence of the catalyst blend 5b of the present invention, to produce 2-thiopropane (dimethyl sulfide) or with ethanol to produce 1-(methylthio)ethane (methyl ethyl sulfide). As another example, ethanethiol (ethyl mercaptan) can be reacted with methanol to produce 1-(methylthio)ethane (methyl ethyl sulfide) or with ethanol to produce 1,1′-thiobisethane (diethyl sulfide). As shown in FIG. 3, the catalyst blend 5b includes a plurality of zones with each zone having a lower volumetric ratio of the alumina diluent B to the hydrotreating catalyst A than the previous zone.
