Definitions

  • the invention relates to the use of polymers containing aminomethylenephosphono groups and their alkali metal or ammonium salts as complexing agents for alkaline earth metal and heavy metal ions in pulp bleaching, cellulose bleaching, cellulose production, paper production, textile finishing and deinking of printed waste paper.
  • complexing agents both in the oxidative and in the reductive bleaching of fibrous materials which are used for the production of paper, in particular wood pulp. Their main task is to complex interfering metal ions.
  • Complexing agents which also used in the paper industry are, for example, nitrilotriacetic acid, ethylenediaminetetraacetic acid and ethylenediaminetetramethylenephosphonic acid.
  • the phosphonomethylated polyvinylamines known from WO-A-91/02011 and the phosphonomethylated polyacrylamides described in DE-A-41 28 510 are used as scale inhibitors and as additives to detergents and cleaning agents.
  • EP-B-0 444 542 discloses the use of N-oxides and of alkylated phosphonomethylated polyethyleneimines as dispersants for aqueous cement compositions containing hydraulic cement.
  • the invention has for its object to provide new complexing agents for the paper industry, the pulp industry, textile finishing and deinking of printed waste paper.
  • the object is achieved according to the invention with the use of polymers containing aminomethylene phosphono groups and their alkali metal or ammonium salts and the N-oxides derived therefrom and the polyammonium salts obtainable therefrom by alkylation as complexing agents for alkaline earth metal and heavy metal ions in pulp bleaching, pulp bleaching, cellulose production, paper production, textile finishing and deinking of printed waste paper.
  • Polymers containing aminomethylene phosphono groups can be obtained by polymerizing the phosphonomethylatable
  • the phosphonomethylated polyvinylamines or copolymers containing vinylamine units described in WO-A-91/02011 are suitable for the purpose of use according to the invention.
  • the quaternary ammonium salts obtainable therefrom by alkylation and the corresponding N-oxides and the polyacrylamides known from DE-A-41 28 510 are also suitable.
  • Phosphonomethylated polyamines and N-oxides derived therefrom and ammonium salts obtainable by quaternization are also suitable for the use according to the invention.
  • Such compounds are known for example from the above-mentioned EP-B 0 444 542. They are made by phosphonomethylation of polyamines.
  • suitable polyamines are all compounds which contain at least as many basic, phosphonomethylatable nitrogen atoms in the molecule that the aminomethylene phosphonates obtainable therefrom have complexing properties.
  • the polyamines also include polyallylamines. The molar mass of the polyamines is, for example, at least 200, preferably 500 to 2 million.
  • Phosphonomethylated polyethyleneimines or their alkali metal or ammonium salts are particularly preferred as complexing agents. These products are obtained, for example, by phosphonomethylating polyethyleneimines.
  • Polyethyleneimines are known to be produced by polymerizing ethyleneimine in the presence of acids, boron trifluoride or halogenated hydrocarbons such as carbon tetrachloride, chloroform, methylene chloride, ethylene chloride or ethyl bromide as a catalyst.
  • the polyethyleneimines have molecular weights of 200 to 2 million, preferably 500 to 1.2 million, polymers of this type are commercially available. They contain structural units of the formula -CH 2 -CH 2 -N- (I),
  • Me H, alkali metal or ammonium equivalent
  • the phosphonomethylated compounds are used, for example, in amounts of 0.02 to 0.5 preferably 0.1 to 0.3% by weight, based on dry fiber material, is used as the complexing agent.
  • the polymers containing aminomethylene phosphono groups and their alkali metal and ammonium salts have e.g. an organically bound phosphorus content of 0.005 to 20, preferably 0.01 to 18,% by weight.
  • the above-described polymeric complexing agents which contain all phosphonomethyl groups, are used in wood pulp bleaching, cellulose bleaching, cellulose production, paper production, textile finishing and deinking of printed waste paper.
  • the technical raw materials and auxiliary materials used in paper production mostly contain traces of heavy metals, especially iron and manganese ions.
  • Wood chips that are difficult to bleach and other paper raw materials, such as thermomechanical material (TMP) and chemothermomechanical material (CTMP) often contain a disproportionate amount of iron ions. In contrast to iron-II ions, iron-III ions react with parts of the wood to form dark-colored compounds.
  • the use of the compounds to be used according to the invention in bleaching solutions also saves hydrogen peroxide in oxidative bleaching.
  • the compounds to be used according to the invention are therefore also suitable as complexing agents in textile finishing, in particular in pretreatment, for example prewashing and pre-cleaning, desizing, alkaline decoction and hydrogen peroxide bleaching of textile materials of all kinds, preferably textile materials containing cotton.
  • Textile materials are understood to mean, for example, yarns, woven fabrics, nonwovens or knitted fabrics.
  • hardness builders Due to the ever increasing closing of the water cycle of the paper machines, there is a constant accumulation of hardness builders. This can include lead to precipitation of carbonates and silicates, which can have a direct impact on paper properties, e.g. Strength, absorbency, dyeability and the dust behavior of the paper.
  • the hardening agents can also impair the effectiveness of auxiliaries and the properties of dyes. If the phosphonomethylated polyamines and their derivatives which contain units of form II, III or IV to be used according to the invention as complexing agents are added to the paper stock in the production of paper, the negative influence of the hardness forming agents in the paper production is thereby eliminated or reduced.
  • the use of the phosphonomethylated polyamines to be used according to the invention together with wetting agents has proven useful in the continuous washing of felt. Precipitations of hardness formers with resin glue or cellulose resin and precipitation products of aluminum sulfate are dissolved, so that laying of the wet felts of the paper machines is largely prevented. This keeps the felts drained for a longer period of time.
  • the reaction mixture is stirred at 110 ° C. for a further 20 h.
  • about 170 g of water are distilled off from it under vacuum and the remaining solution is dropped into a methanolic sodium hydroxide solution for precipitation.
  • the amount of sodium hydroxide used corresponds to the acid
  • Example 1 was repeated with the only exception that complexing agent II was now used.
  • the whiteness of the leaves made from the bleached wood pulp was 65.2%.
  • Example 1 was repeated with the only exception that 2% water glass was now used as the complexing agent instead of the complexing agent I.
  • the whiteness of the sheets obtained from the bleached wood pulp was 65.2%.
  • Comparative example 1 was repeated with the only exception that 0.2% diethylene triamine penta acetate in the form of the sodium salt was used instead of water glass. The whiteness of the leaves obtained from the bleached wood pulp was 65.5%.
  • Example 3
  • the bag is placed in a water bath at a temperature of 60 ° C. for 1 h.
  • the bleached wood pulp suspension is then turned into paper sheets with a weight per unit area on a Rapid Koethen sheet former
  • Example 1 35 400 g / m 2 produced and - as indicated in Example 1 - determined the whiteness of the paper sheets.
  • the paper whiteness was 64.1%. Paper sheets with a whiteness of 54.2% were obtained from the unbleached paper stock.
  • Example 3 was repeated with the only exception that complex complexing agent II was now used instead of the complexing agent used there.
  • the whiteness of sheets of paper made from 45 bleached wood chips is 63.8%. Comparative Example 3
  • Example 3 is repeated with the only exception that 0.06% diethylenetriaminepentaacetate is now used as the complexing agent.
  • the whiteness of sheets of paper made from a wood pulp bleached in this way is 62.8%.
  • the measured values given in examples and comparative examples are average values from 10 individual measurements.
  • An effect advantage for a complexing agent of at least 0.5 percentage points in the degree of whiteness can already be described as significant.
  • the adsorption behavior of the phosphonomethylated polyethyleneimines on the sewage sludge in sewage treatment plants has proven to be particularly advantageous. They can thus be largely removed from the wastewater from paper factories.
  • a static adsorption test was carried out to determine the adsorption potential of the phosphonomethylated polyethyleneimines on the activated sludge.
  • the DOC determination i.e. determination of the dissolved organic carbon
  • the complexing agent I had a DOC adsorption degree of approximately 90%, largely independent of the initial concentration, after a dwell time of 3 h.
