Methane sulphonic acid density
Methanesulfonic acid (MsOH) or methanesulphonic acid (in British English) is an organosulfuric, colorless liquid with the molecular formula CH3SO3H and structure H3C−S(=O)2−OH. It is the simplest of the alkylsulfonic acids (R−S(=O)2−OH). Salts and esters of methanesulfonic acid are known as … Meer weergeven The first commercial production of MSA, developed in the 1940s by Standard Oil of Indiana (USA), was based on oxidation of methylsulfide by O2 from air. Although inexpensive, this process suffered from a poor product … Meer weergeven Since ca. 2000 methanesulfonic acid has become a popular replacement for other acids in numerous industrial and laboratory applications, because it is: (1) a strong acid, (2) has a low vapor pressure (see boiling points in the … Meer weergeven • Trifluoromethanesulfonic acid - the more acidic trifluoro analogue Meer weergeven WebTwo metal organic frameworks bearing sulfonic acid moieties are investigated: HSO3-MIL-101(Cr) synthesized following different approaches and a new structure based on HSO3-bdc and Zr.
