| Abstract: | Dibromoneopentyl glycol chlorophosphate was prepared by reaction of dibromoneopentyl glycol and phospous oxychloride in the presence of triethylamine. Then titled compound was synthesized by as-prepared phosphate and 1, 2, 3-trihydroxybenzene. The over yield was 71.3%. The structure of product was confirmed by elementary analysis, IR, MS and ~1H NMR. The termogravimetry showed that it had high thermal stability and excellent char-forming ability. The beginning temperature of the product decomposition was ab... |
