Simulation Experiments on Effect of Reaction Conditions for the Formation of Organic Sulfides

Key words:

Abstract: Orthogonal experimental on the system of noctylic acid and magnesium sulfate were carried out to investigate the relationship among temperature, reaction time and the amount of water in the system. The results show that temperature is the critical factor in the process of the formation of organic sulfides, which gives contributions of 59% to the experimental results. The second is the amount of water, 26 percent, and reaction time gives less effect. And also, the thermal simulation experiments and kinetics for systems of noctylic acid with magnesium sulfate and noctane with magnesium sulfate were carried out. It is shown that solid magnesium sulfate could react with noctylic and noctane gas to produce magnesium oxide, hydrogen sulfide, coke, carbon dioxide, and organic sulfides as the main products. With the increasing temperature, the conversion of inorganic sulfur to organic sulfur especially to thiophene sulfur increases. The values of apparent activation energy for noctylic acid with magnesium sulfate and noctane with magnesium sulfate are 45.23 kJ·mol1 and 48.6 kJ·mol1.
