Hardcover Abstract: Volume IV/1 contains information on the densities of liquid systems. It may be considered as a supplement to volume II/1 of the 6th Edition, which contains only a few data on nonaqueous systems. Data are not listed for all systems but primarily for those of greater interest where data for a larger range of concentrations were available.

- 含量分析:取预经105℃干燥2h的试样3g(称准到mg)，放入一蒸馏瓶中，加50%磷酸200ml。煮沸2h并收集馏出液。在蒸馏过程中通过滴液漏斗加水，使蒸馏瓶中容积保持约200ml。用酚酞试液(TS-167)作指示剂，用lmol/L NaOH液滴定馏出液。每Ml Imol/LNaOH液相当于丙酸钾(C3 H5KO2)112.17mg。
