General description
三氧化硫 (SO 3 ) 是硫的氧化物。在含硫燃料燃烧过程中释放。在钒催化剂存在下，二氧化硫氧化生成三氧化硫。对该反应的动力学进行了研究。用密度泛函理论和从头算 方法研究了 SO 3 水解成硫酸的过程。
Application
三氧化硫 (SO 3 ) 可用于甲烷磺化合成甲磺酸 (MSA)。

Sulfur emission from a Victorian brown coal was quantitatively determined through controlled experiments in a continuously fed drop-tube furnace under three different atmospheres: pyrolysis, oxy-fuel combustion, and carbon dioxide gasification conditions. The species measured were H(2)S, SO(2), COS, CS(2), and

Polysaccharide extracted from Ulva pertusa (Chlorophyta) is a group of sulfated heteropolysaccharide; for simplicity, the sulfated polysaccharide is referred to as ulvan in this paper. In this study, different sulfate content ulvans were prepared with sulfur trioxide/N,N-dimethylformamide (SO3-DMF) in formamide
