Abstract
NaCl-NaH2PO2-Zn(H2PO2)2-H2O
dörtlü sisteminin katı-sıvı faz dengeleri 333.15K’de izotermal çözünürlük
metoduna göre yapılmıştır. Bu tuzların doygun çözeltideki çözünürlük verileri
tespit edilmiştir. Bu dörtlü sistemin NaCl, NaH2PO2.H2O
ve Zn(H2PO2)2.H2O’den oluşan üç kristallenme alanlı, tek ötonik noktalı
basit ötonik tipli olduğu bulunmuştur. Çalışılan bu dörtlü sistemin ötonik
noktasının bileşimi %6.79
Zn(H2PO2)2, % 43.13 NaH2PO2,%6.71
NaCl ve %43.37 H2O olarak tespit edilmiştir. Ayrıca ötonik noktanın
100 mol tuz bileşimi 5.44 mol Zn(H2PO2)2, 76.62
mol NaH2PO2 ve 17.94 mol NaCl olarak hesaplanmıştır. Zn(H2PO2)2’in
kristallenme alanı en geniştir, aynı zamanda çözünürlüğü en düşük olandır ve
kristalizasyonla kolayca ayrılabilir.
