摘要： The preparation and use of mixed salts of hydroxyalkane sulfinic acids and optionally hydroxyalkane sulfonic acids as a reducing agent are disclosed. The reducing power of the salts is significantly higher than the reducing power of the corresponding zinc salt. The storage stability of the salts as solids and as aqueous solution is significantly higher than one of the corresponding sodium salts.

摘要： A sulfonic acid salt composition includes compounds of formula (I), wherein n is 1 or 2, R1 is H or C1-C6 alkyl, R2 is COOM, SO3M or CH(OH)SO2—OM, each M is an equivalent of a multivalent metal, preferably magnesium, calcium, aluminum, zinc and combinations thereof. The molar ratio of a compound wherein n is 1 to a compound wherein n is 2 is below 0.1. The sulfonic acid salt composition is useful for color stabilization of non-living organic matter such as from lacquers, paints, powder-coatings, and polymers in particular water-absorbent polymers.

摘要： The invention relates to the use of a synergistically active composition which comprises at least one metal sulfite and at least one metal hydroxymethane sulfmate as reducing agent in emulsion polymerizations.The reducing power of the composition of the invention is significantly higher than the additive reducing power of the components. Furthermore, the composition results in a reduced amount of free formaldehyde.
