脂肪醛和脂肪酮凝聚型性能与分子结构的关系

Relationship Between Cohesive Properties and Molecular Structure for Aliphatic Aldehydes and Aliphatic Ketones

用拓扑学的方法探讨了脂肪醛和脂肪酮的结构性能关系，提出了一个能表征和预测脂肪醛和脂肪酮凝聚型性能的普适性定量关系式，对脂肪醛和脂肪酮的沸点、密度、折光指数和临界温度的计算结果表明，计算值与实验值有较好的一致性。

Having discussed the structure-property relationship for aliphatic aldehydes and aliphatic ketones,the author proposes a quantitative relation that can characterize and predict the cohesive properties,such as densities,refractive indexes,boiling points and critical temperatures.The calculated results show that the predicted values are in good agreement with the experimental ones.
