【摘要】 为了表述和估计直链烷基苯的性质,提出苯基位置指数.该指数与直链烷基苯的沸点以及气相色谱保留时间存在良好的相关关系.结果表明:直链烷基苯的异构体和低碳烷基苯的苯基位置指数作为一种拓扑指数,可应用于结构-性质相关关系的研究.更多还原

【Abstract】 In order to describe and estimate properties of straight chain alkylbenzenes,the phenyl site index was proposed.The good correlation between the phenyl site index and the properties (such as boiling point and gas chromatographic retention time) was ob- tained.It was shown that the phenyl site index of straight chain alkylbenzene isomers and low-carbon alkylbenzenes is a useful topological index and can be applied to structure- property correlation.更多还原
