    摘要： A novel, salt-free monoamphopropionate amphoteric surfactant is prepared in yields of from 75% to 80%, from a reaction comprising an imidazoline and a mixture of acrylic acid and sodium acrylate in an aqueous medium. The acrylic acid/sodium acrylate mixture is comprised of the two components in a range of molar ratios of from about 1:6 to about 1:3, respectively, and by replacing methyl acrylate, the reaction does away with the production of methanol which is an unwanted, hazardous and toxic byproduct. The imidazoline reacts in amounts in excess of 90% resulting in the highly pure yields and any left over unreacted acrylic acid can be easily removed by treating it with sodium bisulfate.

    摘要： A process for the neutralization, clarification and decolorization of organosilanes or organosilicones derived from the reaction of an organosilane or a hydropolysiloxane with an aliphatically unsaturated compound in the presence of an acidic platinum catalyst, a process for the conversion of a soluble platinum catalyst into an insoluble form and a process for the recovery of a platinum catalyst from an insoluble anion exchange resin which comprises:(a) contacting a reaction mixture of the organosilane or organosilicone with a basic anionic exchange resin having a free amino or quaternized ammonium salt functionality in an insoluble polymeric matrix under conditions suitable to bind the soluble platinum catalyst to said resin;(b) separating said resin containing bound platinum catalyst from the organosilane or organosilicone reaction mixture and, optionally,(c) treating the separated resin with an inorganic base to convert the bound platinum catalyst to a recoverable salt or(d) subjecting the resin containing bound platinum catalyst to combustion to recover elemental platinum.
