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展,包括二苯甲酮类、氯代甲类、异氰酸类、酰氯类、碳酸类化物。

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、碱催化下的氧化应,是成二苯乙烯(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。
