摘要： 由于含硅有机物测量所需纯样的制备困难,且有些含硅有机物燃烧不完全,难以用氧弹量热法准确测定生成热,所以它们的标准生成热大多未见报道[1,2],而这些数据又是研究有机硅化学热力学和反应性的重要参数,因此有必要建立一套简单而准确的估算方法[2].

Abstract: This paper analyzes the relation between the standard heats of formation of XSiRxH3-x and the group electronegativity proposed by the author for group Xand builds up two methods for calculating the standard heats of formation of alkylsiliane derivatives.Besides, two formalas for calculating the dissociation energies of X—SiRxH3-x are suggested.

Key words: Alkylsilane derivatives, Group electronegativity, Standard heats of formation, Bond dissociation energy
