<strong>摘 要：</strong>
<span>提出了一种基于元素和化学键的估算有机物临界压力的新方法。在有机物临界压力实验数据的基础上,回归出了4个临界压力估算式和估算式的参数值。对400余种有机物的临界压力进行了计算,其平均相对误差为5.013 3％,总体估算精度明显优于相比较的基团贡献法,对环烃类、酮类、醚类、含环氧键类、含苯环类,尤其是对烷烃类、卤代烃类、酯类和含硫类化合物的估算误差明显减小。</span>
<span><abstract>new method, elements and chemical bonds contribution method, was developed for estimating critical pressure of organic compounds. Four correlations had been established via this method. The average
relative percentage error was 5.013 3%,much smaller than that of the commonly used group - contribution method for cyclane, ketone, ether, epoxy, aromatic compounds, especially for paraffinic hydrocarbon, halo-hydrocarbon,ester and organic sulphide compounds.</span>
