三硝酸六尿素合铁〔Fe(N_2H_4CO)_6〕(NO_3)_3是一种含氮和铁的复合肥料。G.Malguori曾测定过硝酸铁在水中的溶解度,H.Kakinuma等都报道过尿素在水中的溶解度。对尿素——硝酸铁——水体系的溶解度相图,仅仅有等用多温法进行过研究。本文提供了尿素——硝酸铁——水体系在20℃和60℃两个温度下的溶解度相图数据,在65℃以上由于该三元
Three urea nitrate [Fe (N_2H_4CO) _6〕 (NO_3) _3 is a compound fertilizer containing nitrogen and iron. G. Malguori has measured the solubility of ferric nitrate in water, H.Kakinuma et al have reported the solubility of urea in water. The phase diagram of the solubility of the urea-ferric nitrate-water system has only been studied using the thermophilic method. This article provides data on the phase diagram of the solubility of urea-ferric nitrate-water systems at two temperatures of 20 ° C and 60 ° C. Due to the ternary
