Keto-enol tautomerizing of ethyl acetoacetate was studied by UV.It was conformed that the content of enol ethyl acetoacetate decreased with the increasing polarity of solvents.

本文以紫外光谱为手段研究乙酰乙酸乙酯的酮-式异构现象;所得结果证实其式含量随溶剂极性的增加而减少。

Keto-enol tautomerism is the most common tautomery phenomenon.Keto -enol themselves are the real chemical substance.

酮及作用最普通的现象,它们都真实的化学实体。

In this thesis, the reaction of aldehydes with dimethyl -- dichlorosilane producingdimethylsilyl bis -- enol ethers has been studied.

本文对醛和二甲基二氯硅烷反应合成二甲硅基双醚进行了研究。
