本文提出一套基团参数,用基团参数加和的方法估算有机物的汽化热△Н°_(ν,298)。对296种有机物试算的结果表明,其平均相对误差在2％以內。
In this paper, a set of group parameters is proposed to estimate the heat of vaporization of organic compounds △ Н ° _ (ν, 298) by adding the group parameters. The results of the trial calculation of 296 organic compounds show that the average relative error is within 2%.
