铅-铝与铁-银二系统的液态溶解度很小,熔化时分为二层,故可测定银在铅与铝间及铝在铁与银间的分配比。根据文献中已有的分配数据,铅-银相及有关热化学数据,作者等计算了铅-银,银-铝及铁-铝等液态二元系统中的活度。最后作者等算出了铝脱氧反应的平衡常数,与 Gokcen & Chipman 的实验数据大致相符,惟温度系数尚不能确定,有待将来研究。

The chemical method of organic qualitive analysis is rather time consuming. This paper presents a simple method of identification, utilizing the data obtained chiefly from a few physical measurements. The method is also suitable for identifying new compounds and compounds whose derivation is unknown.Physical properties, such as density, refractive index, boiling point and viscosity are related to the molecular weight and to the chemical constitution of a molecule. The system presented, based on these correlations, enables one to tell the kind as well as the number of functional groups, to detect the presence and the nature of a ring be it saturated or unsaturated, cyclic or heterocyclic, and to construct the empirical formula of the compound. With the empirical formula, and the kind and number of functional groups established, it is possible by the use of references, such as Beilstein and Chemical Abstracts, to list the physical properties of all possible known isomers. Often the detail structure of nknown can be reasonably ascertained by comparing the physical properties of the unknown with those of the known compounds.The method presented covers liquid substances containing carbon, hydrogen and oxygen only, but the same principle is applicable to those compounds containing sulfur, nitrogen, phosphorus and halogens.

本文提出一有机定性分析的简单方法,主要是根据几种物理常数。这法亦适用于鉴定新的或不知来源的化合物。物理性质,如密度、折射率、沸点及粘度,与分子量及化学结构有关。根据此关系可测定官能团的种类及数目;检验有无环;并求得化合物的实验式。知道实验式及官能团的种类、数目后,可从参考书中查出所有可能异构体的物理性质。比较未知物与已知物的物理性质后,通常即能推定未知物的结构式。本文所述方法只可用于含碳、氢及氧的液态化合物,但同样原理应可用于含硫、氮、磷及卤素的化合物。

The infrared spectra of more than thirty pure saturated hydrocarbons were determined. The equations in terms of average absorption for calculating the composition of CH_3, CH_2, CH_2 and CH_2 groups in saturated hydrocarbons were obtained by using least squares method in matrix form.Comparing the results calculated from the equations mentioned above with the theoretical values of known mixtures and pure compounds, it is shown that the error of such method is as follows: CH_3<±4%, CH_2<±5%, CH_2 and CH_2 <±10%.The...

The infrared spectra of more than thirty pure saturated hydrocarbons were determined. The equations in terms of average absorption for calculating the composition of CH_3, CH_2, CH_2 and CH_2 groups in saturated hydrocarbons were obtained by using least squares method in matrix form.Comparing the results calculated from the equations mentioned above with the theoretical values of known mixtures and pure compounds, it is shown that the error of such method is as follows: CH_3<±4%, CH_2<±5%, CH_2 and CH_2 <±10%.The abnormal phenomena observed from the absorption of the methyl groups on the branched chain at 1340—1400 cm~(-1) were discussed. The absorption coefficient of these methyl groups on the branched chain is about 2.8 times that of the normal methyl groups.The absorption for normal paraffins at 3000 cm~(-1) was found to be consistent with the results reported by Jones, when the value of computed spectral slit width/observed half width of the spectrum (s'/Δν_(1/2)~a) is not more than 0.2. Therefore, this spectral condition may be used as a standard for the intercommunity of spectral data from different laboratories.

根据30多个纯饱和烃的红外光谱数据以及文献数据,并将短阵运算用于最小二乘法,求出了测定饱和烃中CH_3,CH_2,和结构族组成的多重迴归方程式.可用来分析石油馏分饱和烃的结构族组成.经用单体烃和配制的饱和烃混合物校验,求得平均分析误差如下:CH_3<±4%,开链CH_2<±5%,及。讨论了饱和烃支链甲基在1340—1400厘米~(-1)区吸收的反常现象,计算出支链甲基吸收为尾端甲基的2.8倍.在计算光谱狭缝宽度/谱带表观半宽度≯0.2的情况下,所得吸收率与Jones的正烷烃在3000厘米~(-1)处的数据相吻合,作者认为此条件可能成为统一各实验室测定液态烷烃红外光谱数据的标准.
