Direct sulfonation of methane to methanesulfonic acid with SO2 using Ca salts as promoters.

چکیده
Direct liquid-phase sulfonation of methane to methanesulfonic acid (MSA) with SO2 has been achieved in triflic acid using K2S2O8 as the oxidant and a small amount of a Ca salt as the promoter. The effects of reaction conditions on the conversion of SO2 to MSA were examined. Included were the influence of solvent acidity, reaction duration, reaction temperature, amount of K2S2O8, and composition and amount of promoters.

Direct Sulfonation of Methane to Methanesulfonic Acid by Sulfur Trioxide Catalyzed by Cerium(IV) Sulfate in the Presence of Molecular Oxygen
Direct sulfonation of methane with SO3 to methanesulfonic acid (MSA) is accomplished in sulfuric acid with almost 100% selectivity in the presence of a catalyst, namely, Ce and Rh salts and molecular oxygen as the catalyst regenerator. In the absence of O2, the catalyst remains effective but the selectivity to MSA decreases to 53% and byproducts, principally CH3OSO3H, are formed. The effects of...
متن کاملCatalyzed sulfonation of methane to methanesulfonic acid
Direct sulfonation of methane with SO3 to methanesulfonic acid (MSA) and methylbisulfate was investigated in sulfuric acid using Hg(I), Hg(II), and Rh(III)-salts as catalysts. O2 was found to be an important component for the regeneration of the catalyst. The effects of O2 pressure, temperature, SO3 concentration, methane pressure, and catalyst concentration were examined on the rates of SO3 co...
متن کاملA high-yield approach to the sulfonation of methane to methanesulfonic acid initiated by H2O2 and a metal chloride.
Methane is abundant and relatively inexpensive, making it an attractive feedstock for producing bulk chemicals. However, the low reactivity of methane makes it difficult to develop commercially viable processes for methane conversion. Because of favorable thermodynamics, many authors have investigated the oxidation and oxidative carbonylation of methane. By contrast, the sulfonation of methane ...
متن کاملSolvent-free direct ortho C-acylation of phenolic systems by methanesulfonic acid as catalyst
The use of methanesulfonic acid as a Brønsted acid for direct ortho-acylation of phenols and naphthols proves to be a convenient, more general and direct route to various hydroxyaryl ketones. The route is regioselective, leading to ortho C-acylated products in satisfactory to high yields in most cases. The solvent free reactions described below exhibited environmentally benign in terms of faste...
