Parachor Studies at Various Temperatures

Abstract: The parachor, P, as derived by Sugden, has been stated in the form d My\ D-d' where M is the molecular weight, 7 the surface tension, and D and d are the densities of the liquid and vapor respectively at the same temperature.The CHt group.*-By applying the above formula to hundreds of organic compounds and fixing, as a standard for comparison, the covalent bond at zero, Sugden1 arrived at an average value of 39.0 for the CH2 group. This value has been the subject of much discussion ever since. Mumford and P… Show more

“…For many alkylbenzenes an assumption of an average value of 0.86 for density and 1. 49 for refractive index wrould be less in error than to use the published observations. For example, the lowest of the fifteen observations on the density of isobutylbenzene included in Egloff's compilation (95) is 0.8628, although the value now accepted (8) and supported by three recent excellent observations (50,121,142) is only 0.8532.…”
