Abstract

Phase equilibria in CaCl₂–CaCl₂⋅4CO(NH₂)₂–H₂O system sections are studied at temperatures from 0 to –55°C. The earlier hypothesis that the formation of a low-temperature eutectic (–55°C) in the system is caused by CaCl₂⋅4CO(NH₂)₂ is confirmed. A number of low-temperature eutectic mixtures promising for the development of anti-icing reagents on their basis are revealed.

温度为 0 至 -55°C 的 CaCl2-CaCl2⋅4CO(NH2)2-H2O 系统剖面中的相平衡

研究了 CaCl2-CaCl2⋅4CO(NH2)2-H2O 系统部分在 0 至 -55°C 温度下的相平衡。研究证实了之前的假设，即该体系中低温共晶（-55°C）的形成是由 CaCl2⋅4CO(NH2)2 引起的。揭示了一些低温共晶混合物，有望在此基础上开发防冰试剂。
