This paper reviews the research and development of phosgene Derivates,including diphenyl ketone,chlorocarbonate,isocya-nate,acyl chloride and carbonates.

本文综述了光气下游精细化学品的开发及产进展,包甲酮类、氯代甲酯类、氰酸酯类、酰氯类、碳酸酯类化物。

As the isocyan group is polymerized further, diphenyl carbondiimine may be formed, further polymerization of which forms a nitrogen-containing polycyclic aromatic compound.

氰基化物进一步聚基碳化亚胺，后者又聚含氮杂环的多环芳烃。

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、碱催化下的氧化缩反应,是乙烯(烷)类化物的重要途径.

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.

方法以过氧化值(POV)法和DPPH法对提取物进行抗氧化活性的测定,以维素E(VE)和维素C(VC)作抗氧化性能对照。
