摘要
An empirical method for estimating the standard enthalpy of some polar compounds is presended in this paper, that iswhere represents the standard enthalpy difference between CH3-X and R-X(R=Et, i-Pr, t-Bu, etc). It is a new polarity parameter defined by us. A good result was obtained for nearly 70 polar compounds.
