Using acrylamide, siloxane, acrylonitrile, methyl acrylic acid hydroxyl ethyl ester, N. N ' - methylene-bis acrylamide as radiation grafting monomers, the results of comparative tests showed that treated with acrylonitrile and acrylamide, the color of fabrics would be yellowing; 分别采用丙烯酰胺、硅氧烷、甲基丙烯酸羟乙酯、丙烯腈、N,N′-亚甲基双丙烯酰胺作为辐照接枝单体,对比实验结果表明,丙烯酰胺以及丙烯腈处理后的真丝织物颜色发黄;
Study on the Scavenger Activities of Methyl Salicylate against Hydroxyl Radical 水杨酸甲酯清除羟基自由基活性的研究
Methyl lactate is a kind of important hydroxyl ester. It is used in spices and herbicides mainly. 乳酸甲酯是一类重要的羟基酯类化合物,主要用作合成香料和除草剂。
IR analysis shows that the product contains peptide bond, lactone bond, and aliphatic chain GC MS analysis indicates that hydrophobic moiety contains β methyl C 14 fatty acid and β hydroxyl C 18 fatty acid. IR分析表明该物质含有肽键、内脂键及脂肪族侧链等官能团;GC-MS和PC分析表明,其疏水基半分子为β-甲基十四碳脂肪酸及β-羟基十八碳脂肪酸;
The effects of pH, initial methyl orange concentration, reaction time, temperature, concentration of hydroxyl radical, concentration of ozone and flow of ozone on the degradation of methyl orange were studied. 研究了pH值、甲基橙染料废水初始浓度、反应时间、温度、自由基浓度、臭氧浓度及其流量等因素对甲基橙染料降解性能的影响。
