叔丁基羟基茴香醚(BHA)和二叔丁基对甲酚(BHT)的氧化特性和/或代谢产物也许具有致癌性或致瘤性,不过,同样的反应也有可能应对氧化压力。
The oxidative characteristics and/or metabolites of BHA and BHT may contribute to carcinogenicity or tumorigenicity; however the same reactions may combat oxidative stress.
臭氧与DDT的反应性较差, 加入H2O2能有效地去除母体化合物DDT,但不能有效去除其臭氧氧化中间产物的雌激素活性。
Ozonation was shown to be less reactive for oxidation of DDT, and could be enhanced with combination of H2O2, however couldn't get an effective estrogenic activity removal.
催化剂的加入可提高等离子体反应中污染物的脱除效率和二氧化碳的选择性,减少副产物的产生,并进一步降低能耗。
Catalyst could enhance pollutants removal efficiency and selectivity to carbon dioxide in the plasma reaction, inhibit by-products formation and lower energy consumption.
以丙酮为溶剂,30%H2O2为氧化剂,两种体系催化苯甲硫醚氧化反应分别可以循环使用两次和三次,但产物亚砜的对映选择性很低。
The two catalytic systems can be recycled twice and three times, respectively, with very low enantioselectivities for the oxidation of phenyl methyl sulfide with 30% H2O2 as oxidant in acetone.
