烃是构成一切有机化合物的基础,是一类很重要的有机化合物。烃类物质的物性数据对更好地处理和解决设计、科研和生产中遇到的化工技术问题是非常重要的。本文将阐述正构烷烃物性的体算方法,并通过实例说明运算过程。所讨论的两种方法,用于正构烷烃系列,可由正常沸点(即在一个大气压下的沸点,t_b,℃)或链长计算正构烷烃的许多物性数据,如熔点、密度、折射率、表面张力、临界压力、汽化热、粘 Hydrocarbons form the basis of all organic compounds and are a very important class of organic compounds. Physical data on hydrocarbons are important to better address and resolve the chemical technology issues encountered in design, research, and production. This article will elaborate on the nomenclature of n-alkanes physical calculation method, and illustrates the operation process by examples. The two methods discussed, for the n-paraffins series, calculate many of the n-paraffins’ physical properties from normal boiling points (ie, boiling points at one atmosphere, t_b, ° C) or chain lengths such as melting point, density, refractive index, Surface tension, critical pressure, heat of vaporization, stickiness
