The experiment was carried on the waste liquid of molasses alcohol by the way of ozone oxidation and found out that reaction mechanism was free radical reaction under alkaline condition. 利用臭氧氧化法处理糖蜜酒精废液,碱性条件下其反应机理属于自由基型反应。
Alcohol Radical Coating for Clay Green Sand Mold and It's Application 粘土砂湿型用醇基涂料及其应用
The novel methods for synthesis of ethoxylated fatty alcohol carboxylate ( AEC) by catalytic oxidation with a stable free radical nitroxide or a noble metal catalyst were reviewed. 详细介绍了氮氧自由基催化氧化法和贵金属催化氧化法合成脂肪醇醚羧酸盐。
Results: Aqueous extracts of different processed products of Ramulus Cinnamomi were stronger than the alcohol extracts in the scavenging superoxide anion ( O 2-), but weaker in the scavenging hydroxyl free radical(· OH) and the anti lipid peroxidation. 结果:桂枝炮制品水提取物清除超氧阴离子(O2-)能力强于醇提取物,而清除羟自由基(·OH)能力和抗脂质过氧化作用弱于醇提取物。
Addition of inhibitor on free radical ( tert-butyl alcohol) reduced ozone degradation of 2,4-D obviously, showing the importance of free radical reaction path on the 2,4-D degradation. 自由基抑制剂(叔丁醇)的加入,显著降低臭氧化反应去除2,4-D的效果,自由基参与的反应历程对于2,4-D的降解十分重要。
Objective To study the correlation between abusing alcohol and antioxidants, antioxidases and oxygen free radical reaction. 目的探讨滥用酒精与抗氧化剂、抗氧化酶和氧自由基反应的关系。
