摘要:N,N-dimethyl twelve/fourteen quaternary ammonium DSD acid-1,3,5-triazine derivatives containing three-component were prepared through three-step condensation reaction using inexpensive twelve/fourteen tertiary amines as raw materials. The obtained products were confirmed by UV and IR spectrum. The maximum UV absorptions of 5a-i were in the range of 250-350 nm. The absorption peaks of cis- and trans- isomers were in 272-274 nm and 326-328 nm, respectively. The maximum fluorescence emission peaks of the products located in the range of 428-430 nm. The physical properties of the products were performed by whiteness measurement. The results show that the nine products have obvious effect on the filter paper whiteness. In particular, the product 5e have the best effect on the filter paper whiteness at a concentration of 1.6 (o.w.f %), which the value of whiteness is 96.78. © (2013) Trans Tech Publications, Switzerland.
