通过脉冲辐解研究CCl_3OO,与胭脂树橙（BIX）,β-胡萝卜素（β-C）及番茄红素（LYC）在水/醇均相混液中反应.在与CCl_3OO反应过程中,类胡萝卜素本底吸收位置（BIX在500nm左右,β-C在450nm左右,LYC在500nm左右）有明显的漂白,BIX与β-C在650nm左右有反应产物生成过程的吸收峰出现.BIX和β-C与CCl_3OO反应的二级反应速率常数分别为1.78×10~8与7.8×108mol~(-10)·dm~3·s~(-1),LYC与CCl3OO反应只观察到漂白过程,表明LYC与CCl~3OO反应产物在检测范围内没有特征吸收,根据漂白过程求得二级反应速率常数为4×10~7mol~/(-1)·dm~3·s~(-1).
CCl 3OO was studied by pulsed radiolysis and reacted with BIX, β-C and LYC in a water / alcohol homogeneous mixture. During the reaction with CCl 3OO, carrot (BIX at about 500 nm, β-C at about 450 nm and LYC at about 500 nm), and the absorption peaks at about 650 nm for BIX and β-C appeared in the process of BIX and β- The second order reaction rate constants of C and CCl_3OO reaction were 1.78 × 10-8 and 7.8 × 108mol ~ (-10) · dm ~ 3 · s ~ (-1) respectively. Only LYC reacted with CCl3OO, indicating that LYC The reaction products with CCl ~ 300 have no characteristic absorption in the detection range. According to the bleaching process, the second - order reaction rate constant is 4 × 10 ~ 7mol ~ / (-1) · dm ~ 3 · s ~ (-1).
