曾有不少人对有机物的物理性质与结构的关系进行过研究,并提出了一些经验公式。例如Greenshilds归纳了烃类和醇类的各种物理性质(包括多个参数)的计算公式。Ambrose提出计算脂肪醇沸点的公式.Ksiazczak提出计算酚和醇同系物的性质的公式.这些式子多数只适用于一类化合物,且有些计算方法比较复杂。为了归纳一个适用 Many people once studied the relationship between the physical properties and the structure of organic substances and put forward some empirical formulas. Greenshilds, for example, summarize the formulas for the various physical properties of hydrocarbons and alcohols, including multiple parameters. Ambrose proposed a formula to calculate the boiling point of fatty alcohols.Ksiazczak proposed a formula to calculate the nature of the phenol and alcohol homologues.Most of these formulas apply only to a class of compounds and some are computationally complex. In order to sum up a suitable
