摘要
以脂肪醛酮为研究对象,选取三种结构参数,并与脂肪醛酮热容、沸点、临界温度和临界体积关联,拟合成4个回归方程,其相关系数分别为0.9995,0.9920,0.9818,0.9950.均达到优良级.本方法计算简单,结构选择性达到唯一性表征.为预测脂肪醛酮热容、沸点、临界温度和临界体积提供了有效的办法.
Three structural parameters were chosen to study aliphatic aldehydes and alkones.Utilizing the link between physical properties of aliphatic aldehydes and alkones and structural parameters,4 linear equations are suggested.The related coefficients are 0.9995,0.992?0,0.981?8 and 0.995?0 respectively.The structural selectivity is unique and the calculation is simple.Therefore,an effective method to forecast heat capacity,boiling point,critical temperature and critical volume of aliphatic aldehydes and alkones is provided.
