摘要： A process to produce N-vinylformamide includes the steps of: reacting hydroxyethyl formamide with a reactant comprising at least one cyclic anhydride group to form an ester, and dissociating the ester via heat in a thin film evaporation to synthesize N-vinylformamide and a compound comprising at least one diacid group, the N-vinylformamide separating from the diacid during the thin film evaporation. The reactant including at least one cyclic anhydride group can, for example, be succinic anhydride, maleic anhydride, phthalic anhydride, (2-docecen-1-yl)succinic anhydride, exo-3,6-epoxy-1,2,3,6 -tetrahydrophthalic anhydride or a polymer including at least one cyclic anhydride group. A process to produce N-vinylformamide comprises the steps of: mixing acetaldehyde, formamide and a source of anhydride in a single reaction vessel, reacting the acetaldehyde, formamide and the source of anhydride in the reaction vessel under pressure, dissociating an ester formed by a reaction between the source of anhydride and hydroxyethyl formamide formed in the reaction vessel to synthesize N-vinylformamide and a compound comprising at least one diacid group.

摘要： A process to produce N-vinylformamide includes the steps of: reacting hydroxyethyl formamide with a reactant including at least one cyclic anhydride group to form an ester, and dissociating (or cracking) the ester to synthesize N-vinylformamide and a compound including at least one diacid group. The ester can be dissociated using heat. The reactant including at least one cyclic anhydride group can, for example, be succinic anhydride, maleic anhydride, phthalic anhydride, a polymer including at least one cyclic anhydride group, or a solid support to which at least one cyclic anhydride group is covalently tethered. Preferably, the cyclic anhydride is regenerated from the diacid formed in the synthesis of the ester by heating the diacid to dehydrate the diacid. The temperature required to dehydrate diacid groups is preferably higher than the temperature use to dissociate the ester.

摘要： The present invention provides methods and compositions for treating clay-bearing aggregates, particularly those used for construction purposes, whereby inclusion of fines is maximized due to minimization of clay washing which tends to remove such fines, and whereby performance of the aggregate-containing construction material is enhanced. Exemplary methods comprise introducing to clay a water-soluble, functionalized polyamine comprising a water-soluble polyamine formed by reacting an amine compound with an epoxy compound, the polyamine thus reacted being functionalized through the use of certain halide, sulfate, or epoxy compounds.
