摘要： A process for the bleaching of chemical pulp, in which process the pulp is delignified with a peracid and additionally the pulp is chelated in order to bind heavy metals, such as Fe, Mn and/or Cu, into a chelate complex. According to the invention, the chelating is carried out using a chemical which has been selected from a group consisting of N-bis-((1,2-dicarboxy-ethoxy)-ethyl)-amine, N-bis-((1,2-dicarboxy-ethoxy)-ethyl)-aspartic acid and N-tris-((1,2-dicarboxy-ethoxy)-ethyl)-amine, as well as the alkali metal and earth-alkali metal salts thereof, and the peracid and chelating treatments are carried out simultaneously by combining the peracid and the said chelating chemical in the same solution phase. In the bleaching sequence the treatment according to the invention may follow, for example, an ozone delignification and precede an alkaline peroxide step, and in the latter case a magnesium compound, such as MgSO4, may be added to the pulp before the alkali step.

摘要： Methods for the preparation of an N-alkyl-N-bis-(2-( 1,2-dicarboxy-ethoxy)-ethyl)-amine derivative are described, products of the methods as well as uses of the products. The derivative is prepared by reacting an alkali or earth alkali metal salt of maleic acid with an N-substituted diethanolamine, the reaction taking place with the two ethanol groups of the diamine while the substituent group bound to the N atom remains unaffected, or alternatively by first reacting diethanolamine with an alkali or earth alkali metal salt of maleic acid to yield N-bis-(2-(1,2-dicarboxy-ethoxy)-ethyl)-amine, which is then reacted with a substitution reagent to obtain the final product. The derivative is useful as chelating agents, e.g., in the bleaching of chemical or mechanical pulp or in textile bleaches containing hydrogen peroxide or a peracid, or as a calcium binder in detergents and cleaning agents.
