Synthesis of (2, 3-Dibromopropyl)Phenyl Octadecanoyl Phospate and Its Application as Softening Flame Retardant

(2,3-Dibromopropyl)Phenyl Octadecanoyl Phosphate 합성과 유연난연제로서의 응용

(2, 3-Dibromopropyl) phenyl phosphate[DPP] was synthesized from 2, 3-dibromopropyl alcohol and chlorophenyl phosphate. Also, (2, 3,-dibromopropyl)phenyl octadecyl phosphate[DPOP] was synthesized from DPP and n-octadecyl chloride. Flame retardants, DPPF and DPOPF, were prepared by blending DPP and DPOP with emulsifier, respectively. The flame retardants prepared were o/w(oil in water) type emulsion flame retardants. As a result of treatments of the flame retardants on various synthetic textiles, DPPF showed only good flame retardancy, but DPOPF showed both good flame retardancy and good softness.

2, 3-Dibromopropyl alcohol과 chlorophenyl phosphate로 부터 (2, 3-dibromopropyl)phenyl phosphate[DPP]를 합성하고, 또한 DPP에 n-octadecyl chloride를 가하여 (2,3-dibromopropyl)phenyl octadecyl phosphate[DPOP]를 합성하였다. DPP와 DPOP에 각각 유화제를 블렌딩시켜 난연제 DPPF와 DPOPF를 제조하였는데, 모두 o/w(oil in water)유화형 난연제였다. 이 2종류의 난연제를 각종 합성직물에 처리하여 난연성과 인열강도를 측정한 결과 DPPF는 난연성만이, 그리고 DPOPF는 난연성과 유연성 모두 양호하였다.
