Hydroxymethanesulfone acid

Hydroxymethanesulfonic acid (HMSA) is a complex formed from formaldehyde and S(IV). It has been detected in atmospheric liquids (i.e., rain and snow). The complex has high resistance to oxidation by oxygen as well as ferric ions and oxygen. Martin et al. (1989) first studied the oxidation of HMSA. Graedel et al. (1986) proposed that Fenton-type reactions are possible in atmospheric liquid water.

Water-soluble organic compounds in urban atmospheric particles can also contain organosulfur compounds. Methanesulfonic acid and hydroxymethanesulfonic acid have been found as the major organosulfur compounds in urban aerosols, most particularly in particles with the diameter range of 0.43-1.1 p.m. Monomethyl hydrogen sulfate has also been detected on urban particles from localities where no oil or coal power plant exist (Suzuki et al., 2001). 

Sodium hydroxymethanesulfinate Dithionites are the starting materials in the manufacture of sodium hydroxymethanesulfonate by the reaction of dithionites with formaldehyde in the presence of sodium hydroxide. In a variant of this process, zine dithionite, as starting material, reacts with formaldehyde in aqueous solution forming zinc salts of hydroxymethanesulfinic acid and hydroxymethanesulfonic acid. The latter is reduced to zinc hydroxymethanesulfinate with added zinc at 90 °C.

HMS is the anion of the strong hydroxymethanesulfone acid (HMSA), full dissociated (Munger et al. 1984). The second dissociation step to HCH(0) S0J corresponds to a weak acid with pK 10 (Sorensen and Anderson 1970). HMS slowly decomposes into the initial substances, thereby sometimes describing (5.286) and (5.288) as equilibrium with Ki.2z6is.2ss = 6.6 10 , A 5,288 = 7.7 and Mauersberger 1995).
