(57) Abstract:The invention relates to organic chemistry, in particular to derivatives of 1,3,5-triazine - 2-trimethylammoniumchloride-4,6-bis(nonaxisymmetric)-1,3,5-triazine structureas cationic type surfactant 1 table. The invention relates to organic chemistry and chemistry of surface-active substances (surfactants), specifically to new, substituted 1,3,5-triazine - 2-trimethylammoniumchloride-4,6-bis(nonaxisymmetric)-1,3,5-triazine structureas cationic type surfactant.As you know, the chemistry of surfactants is booming. This is due not only to the level of sanitary-hygienic preparation of the population, but also the need to develop new, effective, non-toxic and do not cause allergic reactions of compounds capable of lowering the surface tension of liquids and having good detergency even in hard water. The last condition is the best answer cationic type surfactant, a range which, unfortunately, is very limited. Development of new cationic surfactants of the type of task is most important.Known 2-allylamino-4,6-bis(ethoxycarbonylmethyl epoxy oligomers in the anhydrous compositions cure [U.S. Pat. Of the Russian Federation No. 2187505 / S. N. Mickle, A. A., Cesnik, L. D. Konyushkin, C. N. Zaplishny. 2 Allylamino-4,6-bis(ethoxycarbonylmethylene)-1,3,5-triazine as an effective modifier-souvenires epoxy oligomers in the anhydrous compositions of curing. Bull. Fig., 2002, No. 23] (the prototype structure).Its use as surface-active substances is unknown.Known also Tetramethylammonium chloride (TMAH) structureCMAH get known quaternization reaction of dimethylaminoacetyl chloride stands for Hoffman and used as cationic surfactants (cationic surfactant) [Surface-active substances and compositions: a Handbook / edited by M. Y. Pletnev. - M.: OOO “firma Clavel”, 2002, 768 S.]. CMAH successfully used as surfactants and conditioning supplements in conditioners and balms - (prototype).The disadvantage of applying CMAH is relatively low ability to reduce the surface tension of aqueous solutions, as well as the high acidity of solutions.Technical solution to the problem is to increase the ability to reduce the surface tension of aqueous solutions, the new reduction of the derived series of 1,3,5-triazine - 2-trimethylammoniumchloride-4,6-bis(nonaxisymmetric)-1,3,5-triazine (TCT) structurewhich can be used as an effective cationic type surfactants (cationic surfactant).The novelty of the claimed proposal is seen that a new derivative of 2-substituted 1,3,5-triazines as a cationic surfactant that reduces the surface tension of aqueous solutions. The connection has a high surface activity even at high (1 to 10-1wt.%) the dilutions that dramatically reduces consumption by DV and improves the environment.At the same time declared TNCT get known method is the reaction of 2-chloro-4,6-bis(nonaxisymmetric)-1,3,5-triazine with dry, gaseous trimethylamine in a mixture of benzene: ether at a temperature of 20-25 With [A. A., Cesnik, S. M. Mickle, B. C.) and C. N. Zaplishny. CHC, 2002, No. 2, S. 197-203]. The original 2-chloro-4,6-bis(nonaxisymmetric)-1,3,5-triazine get known method, the reaction of cyanuric chloride with p-colorselectiondialog (1:2 mol) in solution in acetone, in the presence of equimolar amount of sodium bicarbonate [Century. N. Zaplishny, I. A. Asaturyan, G. M. Poghosyan. Sint is p cyanuric chloride immediately before use purify by crystallization from CCL4and the solvent is subjected to fractionation and dried by known methods [A. Gordon, R. Ford. Satellite chemist. M.: Mir, 1976, 541 S.].For comparison, the surface activity use a known cationic surfactant Tetramethylammonium (TMAH) - the prototype for the application.Examples of performance stated suggestions are presented below.Example 1. 2-Chloro-4,6-bis(nonaxisymmetric)-1,3,5-triazine (HNAT). A mixture of 1.5 g (0.02 mol) aminouksusnoy acid, 3,47 g (0.02 mol) of nonanol-1 and 3.8 g (0.02 mol) of p-toluenesulfonic acid in 25 ml of benzene is boiled with a nozzle Dean-stark and reflux to the visual termination of water in the nozzle.
