Abstract: An apparatus for measuring critical constants of organic compounds with the meniscus-disappearing method in an open tube was designed and set up. The critical temperatures and critical pressures of five organic compounds were measured. The critical densities of those compounds were determined by "the law of rectilinear diameter".
摘要: <正>1引 言 临界参数属于最重要的物性数据之一,很多作者曾对已发表的实验数据进行搜集和整理迄今为止,有临界参数实验值的物质并不很多,在有机化合物中约400种,很多重要化合物至今还没有临界参数的实验数据。在现有的数据中,有很多是几十年甚至一个世纪以前所测的,比较不同时期不同作者对同一种物质的测定结果就会发现差别往往较大,有时甚至相去甚远,这说明有些数据可靠性很差。以上表明,有待于进行的工作还很多
