(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 structure

as 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 structure

as 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) structure

CMAH 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) structure

which 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.

While they prepare aqueous solutions of a concentration of 0.1-10.0 wt.% and measure the value of the surface tension (n/m) by a well-known method Rehbinder [A. Schwartz and J. Perry. Surfactants. M.: Izd. IL, 1953, S. 263]. For comparison, using an aqueous solution of Tetramethylammonium chloride (TMAH) the appropriate concentration. As a control, use the variant with the water that does not contain any additives. Received data (the results of three measurements) were averaged, and the average values were used for further calculations. Surface activity in % of control was determined by the formula

=a-bi/ini100%,

where a and bi- the value of the control sample and experimental, respectively. The results are summarized in table.

As can be seen from this table that the application of the proposed TND as a cationic surfactant leads to the following results.

If TNTC, use it as a cationic type surfactant at a concentration of 0.01 to 10.0 wt.% reduces the value in comparison with control by 40.7-261,5% (19,6-50,5 instead 71,0 n/m), while the use of known Tetramethylammonium chloride reduces this figure in comparison with what imago surfactants in comparison with the known decreased by 1.62% pH (pH value 1% aqueous solution 4,92 for TNTC, instead of the pH of 3.3 to 1%-aqueous solution of a known TMAH).

Thus, the use of the claimed TNTC as cationic type surfactants significantly reduce the magnitude of the surface tension of their aqueous solutions, and also to reduce the acidity of the solutions, which is very important from the point of view of subsequent practical application, since the solutions have a high surface activity even at high (1 to 10-1wt.%) the dilutions and low acidity, which reduces consumption by DV and improves the environment.
