Abstract:
With the model that the number of repeating units of the homologous series varise successively, they were able to described as the following equations: P=a+bn(1/c),where a、 b、 c all refer to the constants, n to the number of repeating units, p to the physical properties of homologous straight-chain alkanes compounds series. Significant correlation was found between the physical properties of homologous straight-chain alkanes series and their number of repeating units in this models.

摘要:
以直链烷烃同系物结构重复单元数值连续变化为模型假定,获得了描述直链烷烃同系物物理性质递变规律的数学表达式:P=a+bn(1/c),其中a、b、c均为常数,n为结构重复单元数值,P为直链烷烃同系物的物理性质。通过非线性回归分析,得到回归方程,结果表明直链烷烃同系物的物理性质与重复单元数值之间满足上述关系式,均显示优良的相关性。
