Definitions

  • the invention relates to an aid for improving the retention of washable solids, for accelerating the dewatering of suspensions and for the faster treatment of industrial water, waste water and sludge by adding basic water-soluble polymers as an aqueous polymer solution, in particular in the paper industry.
  • DT-AS 15 46 290 describes reaction products made from polyalkylene polyamines and bifunctional polyalkylene oxide derivatives which are suitable for the flotation of fibers and fillers from paper machine waste water, but not at the same time, as would be desirable, for use as retention and Drainage aids are equally suitable in the paper industry.
  • US-PS 35 75 797 viscous flotation agents for paper machine waste water are described.
  • These flotation agents are reaction products of polyalkylene polyanines with polyethylene glycol derivatives which contain at least 2 chloroformate groups. Unfortunately, these products can only be prepared as a 10% solution and, moreover, have only relatively low retention and drainage capacities on.
  • mol of the polyethylene glycol of the general formula where x is an integer between 1 and 27, is formed with 2 moles of epichlorohydrin, with 0.5 to 7 moles, based on polyalkylene polyamine of the basic polyaminoamide as the known second partial product B, with subsequent reaction of the intermediate product AB thus formed with the polyfunctional connection.
  • auxiliaries can be obtained in the above-mentioned manner which, for example in 20% by weight aqueous solution at 25 ° C., have a viscosity of 50 to 1000 cp on the one hand.
  • the above-mentioned newsprint suspension is obtained by mechanical defibration of commercially available newsprint and subsequent speck-free beating of the defibrated product in a conventional kitchen mixer.
  • the measurements are carried out at a pH of 6.5 and 4.8, which is adjusted with a 1% by weight aqueous alum solution.
  • the fiber concentration is 2g / l water.
  • the 0 sample listed in Table 5 is of course dependent on the choice of waste paper used.
  • the reaction takes place at a reaction temperature of at most 65 ° C in a time of 2.5 hours in the form of an addition reaction.
  • the resulting product namely polyethylene glycol-bis- ⁇ -hydroxy- ⁇ -chloropropyl ether, is now added with 35.4 g DTRA, corresponding to 0.336 moles, after adding 271.7 ml deionized water, which is stirred in at 65 ° C. in two minutes moved an inlet funnel.
  • the temperature is adjusted if necessary
