将作者提出的气相色潜中同系物的保留指数与同系序数间的定最关系用于脂肪醇在15种固定相上保留指数的关联和计算。确定了4种端基在15种固定相上的当量参数,用试验和大量文献数据证明所提方法是准确可靠的。进而指出端基当量参数与温度的近似直线关系,据此,可进行更大范围内的保留指数的预测。 The relationship between the retention index and the same ordinal number of the gas chromatophysical potential homologues proposed by the authors was used to correlate and calculate the retention index of fatty alcohols on 15 stationary phases. The equivalent parameters of four kinds of end groups on 15 kinds of stationary phases were determined. The experimental results and the large amount of literature proved that the proposed method is accurate and reliable. Furthermore, the approximate linear relationship between the equivalent parameters of end groups and temperature is pointed out. Based on this, a larger range of retention indices can be predicted.
