Abstract
Since the properties of sulfur-containing compounds depend on the number of sulfur atoms (sulfur number) contained in the compounds, it is desirable to develop a method to control the sulfur number. A common method for synthesizing sulfur-containing compounds is to mix sulfur with a base to form linear sulfur, which is then reacted with an organic compound to obtain a sulfur-containing compound. In this study, we systematically investigated the relationships between the type of base, equivalent amount of base, the reaction solvent, and the sulfur number in the resulting sulfur-containing compound. The sulfur numbers of sulfur-containing compounds prepared in water were controlled by the equivalent ratio of elemental sulfur (S8) and base. Sulfur-containing compounds with high sulfur values were obtained using solvents with low dielectric constants and with lower base equivalents compared to S8.
We systematically investigated the relationship between the type of base, equivalent amount of base, the reaction solvent, and the number of sulfur atoms in a sulfur-containing compound. The number of sulfur atoms in sulfur-containing compounds prepared in water was controlled by the ratio of sulfur and base.
