摘要:

考察了亚氨基二乙腈晶体的晶习,测定了亚氨基二乙腈在水溶液中的溶解度和介稳区数据,同时考察了降温速率对介稳区宽度的影响.结果表明,亚氨基二乙腈在水中的溶解度随温度的升高而增加,且高温时增长幅度大;降温越快,结晶过程的介稳区越宽即系统的过饱和度越大.

Abstract:

The crystal habit of iminodiacetonitrile crystals was investigated, the solubility and metastable zone data of iminodiacetonitrile in aqueous solution were determined, and the influence of cooling rate on the width of the metastable zone was investigated. The results showed that the solubility of iminodiacetonitrile in water increased with the increase of temperature, and the increase range was large at high temperature. The faster the cooling, the wider the metastable zone of the crystallization process, that is, the greater the supersaturation of the system.
