两种芳香酯的合成及其荧光特性

Synthetic and spectrum characteristic of the aromic ester

报道了顺丁烯二酸二间甲苯酯和邻苯二甲酸二间甲苯酯的合成与光谱性质.由顺丁烯二酸酐或邻苯二甲酸酐与间甲基苯酚在浓硫酸催化下反应得到了两种新的二元酸酚酯,通过核磁共振谱、红外光谱及质谱确定了其结构.并通过紫外可见光谱和荧光光谱比较了目标化合物的光谱性质,证实了芳香酯类化合物有较好的荧光特性.

The syntheses and spectral characteristics of bis-m-methylbenzene maleate and bis-m-methylbenzene phthalate is reported in this paper. Through maleic anhydride or phthalatic anhydride reacting with m-methyl phenol by sulphuric acid catalysis, two kinds of new compounds is are obtained. The structure of two compounds is confirmed by ^1H NMR, ^13CNMR, IR and MS spectrum. Comparing with the spectrum characteristics of the two compounds through UV-Vis spectrum and fluorescence spectrum, It is proved that the aromic esters compounds have better fluorescence characteristics.
