Definitions

  • the present invention relates to the production of basic polycondensation products which can be obtained by reacting polyfunctional amines with aqueous acids, distilling off the water and then anhydrous polycondensation with cyano compounds.
  • Processes known in the prior art for producing comparable polycondensation products are based on the reaction of polyfunctional amines with ammonium salts and subsequent polycondensation with cyano compounds. Such processes could be optimized by adding solvents, as described for example in EP 0 431 423 B1 and EP 0 692 511 B1.
  • EP 0 938 515 B1 describes a process in which polyfunctional amines are reacted with cyano compounds in the presence of sulfamic acid or its salts with the addition of solvents. The reaction is shown in Reaction Scheme 1.
  • No. 6,008,316 A describes a process for the reaction of polyamines which can be obtained by polycondensation of monomeric amines with cyano or guanidino compounds. The reaction is shown in Reaction Scheme 2.
  • the object of the present invention is in particular to improve the methods of the prior art or to provide known products.
  • the present invention therefore relates to a process for the preparation of basic polycondensation products, characterized in that a) a polyfunctional amine selected from 1,4-butanediamine, 1,6-hexanediamine, N- (2-aminoethyl) - l, 3-propanediamine, dipropylenetriamine, N, N-
  • This process can be carried out in a controlled manner and with very high process reliability.
  • the reduction in the amount of ammonia released compared to completely anhydrous processes is the most important criterion for the technical implementation of the process.
  • These polycondensation products can be prepared in solvents, and it is also possible to accelerate the reaction by adding a catalyst.
  • Basic polycondensation products according to the invention can be neutralized with aqueous acid and then used to improve the fastness properties of textile dyeings or as pre-cationizing agents when dyeing textiles.
  • the aqueous solutions of acids used are inorganic or organic acids.
  • Preferred inorganic acids are, for example, hydrochloric acid or sulfuric acid and preferred organic acids are, for example, formic acid or acetic acid.
  • the distillation conditions for removing the water must be adapted to the reaction mixture.
  • the distillation is preferably carried out at temperatures up to a maximum of 180 ° C. It can take place under vacuum or under normal pressure, or it can begin under normal pressure and be completed under vacuum to complete the distillation.
  • Suitable cyano compounds for the process are, for example, cyanamide, dicyandiamide, guanidine or biguanidine.
  • the condensation reactions between the polyfunctional amine derivatives and the cyano compounds preferably take place in the temperature range from 100 ° C. to 250 ° C., preferably in the range from 120 ° C. to 230 ° C.
  • solvents are, for example, polyhydric alcohols such as ethylene glycol, di-, tri- or
  • Tetraethylene glycol, propylene glycol, butylene glycol and polyethylene glycol Tetraethylene glycol, propylene glycol, butylene glycol and polyethylene glycol. Mixtures of different solvents can also be used. If solvents are used, the addition can take place both at the beginning of the process and before the polycondensation with the cyano compound. The use of solvents reduces the viscosity during polycondensation.
  • a catalyst can optionally be added to accelerate the process.
  • Suitable catalysts are metal halides, such as zinc chloride.
  • the addition of a catalyst is not absolutely necessary to carry out the process.
  • the basic polycondensation products produced according to the invention can be used, for example, as textile treatment agents, in particular as aftertreatment agents to improve the fastness of dyeings or as pre-cationizing agents in dyeing.
  • Example 2 Parts of water added. In this way, 810.0 parts of a yellow to reddish solution were obtained. The amount of ammonia released is shown in the table.
  • Example 2 Example 2:
  • the temperature was then raised to 160 ° C. and this
  • Dicyandiamide added and heated to 160 ° C within 90 minutes, stirred at 160 ° C for 30 minutes and cooled to 100 ° C within 45 minutes. 25.5 parts of ammonia split off. Then 214.1 parts of water were slowly added, the temperature falling below 100
