1.This paper reviews the research and development of phosgene Derivates,including diphenyl ketone,chlorocarbonate,isocya-nate,acyl chloride and carbonates.
2.As the isocyan group is polymerized further, diphenyl carbondiimine may be formed, further polymerization of which forms a nitrogen-containing polycyclic aromatic compound.
异基化合物一步二聚成二苯基碳化二亚胺,后者又聚合生成含氮多芳烃。
3.The oxidative dimerization of aryl methanes in organic solvents by using alkaline catalysts is an important way to prepare diphenyl ethanes and diphenyl ethylenes.
芳基甲烷在有机溶剂介质中、碱催化下氧化缩合反应,是合成二苯乙烯(烷)类化合物重要途径.
4.Methods Using the assay system of peroxide value (POV), diphenyl picryl-hydrazyl (DPPH), the antioxidative activities of various extracts were studied and comparedwith VE and VC.
