采用线性程序升温毛细管气相色谱法测定了几种酮类化合物的保留指数。以2-酮为标准进行指数计算。三次测定的95%置信区间为±0。13指数单位。这些保留指数和每个化合物的零、一、二级分子连通性因子用多元回归处理得到方程来预测。注意到对称酮的保留有一个有趣的趋势，并在屏蔽羰基氧的基础上加以合理化。
The retention indices (I) for a number of ketones were determined using linear temperature-programmed capillary gas chromatography. 2-Ketones were used as standards for the index calculations. The 95% confidence interval for triplicate determinations was found to be ± 0. 13 index unit. These retention indices and the zero-, first-, and second-order molecular connectivity factors for each compound were treated with multiple regression to yield equations to predictI. An interesting trend in the retention of symmetric ketones was noticed and rationalized on the basis of shielding of the carbonyl oxygen.
