    • A method for the “dry” production of sodium percarbonate (dry process), in which monohydrate crystals of sodium carbonate are reacted with a quasi-stoichiometric quantity of concentrated aqueous hydrogen peroxide solution, relative to the quantity of active oxygen required in the sodium percarbonate to be produced. This method can be combined to great advantage with subsequent compaction of the sodium percarbonate obtained. Sodium percarbonate products containing varying concentrations of active oxygen of at least 10 weight percent, particularly high active oxygen concentrations of above 14.5 weight percent, can be produced. The resulting sodium percarbonate products are distinguished in that they have remarkably advantageous dissolution rates, stabilities and compatibility with detergent bases, and are superior to conventional sodium percarbonates obtained, for example, by a crystallization process. The invention also relates to the sodium percarbonate products obtained and to detergent compositions containing such sodium percarbonate products.
    • 相对于过碳酸钠中所需的活性氧的量,将碳酸钠的一水合物晶体与准化学计算量的浓缩的过氧化氢水溶液进行“干”生产过碳酸钠(干法)的方法 要生产。 所得到的过碳酸钠随后的压实可以将该方法组合起来具有很大的优势。 可以生产含有至少10重量%的不同浓度的活性氧的过碳酸钠产物,特别是高于14.5重量%的特别高的活性氧浓度。 所得到的过碳酸钠产物的特征在于它们具有非常有利的溶解速率,稳定性和与洗涤剂碱的相容性,并且优于例如通过结晶方法获得的常规过碳酸钠。 本发明还涉及所得的过碳酸钠产品和含有过碳酸钠产品的洗涤剂组合物。

    • Cationic epoxy resin esters suitable as binders for stoving coating compositions, particularly for application by electrodeposition, and as mill base resins for grinding pigments and extenders; and a process for producing same is described. The resin esters are produced through reaction of a resinous compound carrying at least two 1,2-epoxy groups with carboxylic acids and, optionally, with primary and/or secondary alkyl- and/or alkanolamines. The carboxylic acid employed, totally or partially, is the reaction product of a dicarboxylic acid anhydride and a tertiary amine which has the structure - ##STR1## wherein R and R.sub.x are a hydrogen atom or an alkyl radical or an aryl radical which may be substituted, R.sub.7 is an alkyl radical, an amino-alkyl radical having the primary amino groups, if present, blocked (as a ketimine) or the moiety remaining after the reaction with an active hydrogen atom of an acrylic or methacrylic monomer monofunctional with regard to the double bond, and wherein n is 2 or 3, the quantity of basic component being chosen in order that the epoxy-free final product has an amine value of at least 35, and preferably of from 40 to 140 mg KOH/g.
