The wet air co-oxidation (WACO) of a major commercial polybrominated diphenyl ether flame retardant congener, decabromodiphenyl ether (BDE209), was investigated using tetrahydrofuran (THF) as an initiator in a stainless autoclave at temperature range of 120-170 degrees C and 0.5MPa oxygen pressure. Compared to the single oxidation of BDE209 under the same conditions, the addition of THF in the reaction system greatly improved the removal efficiency of BDE209. The effect of temperature on the reaction was studied. The removals of BDE209 and Br increased with increasing temperature. In addition, the effect of NaNO(2) as the catalyst on the WACO was also investigated and the results showed that the addition of NaNO(2) could improve the Br removal efficiency.
在不锈钢高压釜中，以四氢呋喃（THF）为引发剂，在120 - 170℃温度范围和0.5MPa氧气压力下，研究了一种主要的商业多溴二苯醚阻燃剂同系物十溴二苯醚（BDE209）的湿空气共氧化（WACO）过程。与相同条件下BDE209的单一氧化相比，反应体系中加入THF大大提高了BDE209的去除效率。研究了温度对反应的影响。BDE209和溴的去除率随温度升高而增加。此外，还研究了亚硝酸钠作为催化剂对WACO的影响，结果表明加入亚硝酸钠可提高溴的去除效率。
