摘要：The cetyl \ octadecyl dimethyl tertiary amine(percentage composition 7:3)is a very common and inexpensive chemical raw material in the chemical market. In this paper, a series of the new chemical composite DSD acid-triazine structure containing long chain quaternary ammonium salt fluorescent brighteners (FBs) were synthesized through a three-step condensation reaction of cyanuric chloride, DSD acid, cetyl \ octadecyl dimethyl tertiary amine and amino compound. The obtained compounds were characterized by the analysis of the IR spectrum, UV spectrum and fluorescence excitation and emission spectrum, and whiteness were tested through dyeing filter paper. The results show that compounds 7a-j have the obvious UV absorption, fluorescence emission and dyeing properties, with a wider absorption, emission wavelength range and enhancing fluorescence quantum yield, achieving the synergetic enhancement effect by compounding. © (2013) Trans Tech Publications, Switzerland.
