本文研究了在少量FeCl_3的存在下,当溶液的PH=11～13时,对氨基酚与次氯酸钠及苯氧负离子的氧化偶合反应。结果表明,反应所生成的有色化合物在λ=632nm处有最大吸收,且表观摩尔吸光系数ε_(632)=4.0×10~4L·mol~(-1)·cm~(-1)
In this paper, we studied the oxidative coupling reaction of p-aminophenol with sodium hypochlorite and phenoxyanions in the presence of a small amount of FeCl_3 when the pH of the solution was between 11 and 13. The results showed that the maximum absorption of the colored compounds at λ = 632 nm and the apparent molar absorptivity ε 632 = 4.0 × 10 4 L · mol -1 cm -1,
