Application of liquid fertilizers can significantly improve the fertilizer utilization efficiency and labor efficiency. Phase equilibrium of various fertilizers in aqueous solution is the basis of manufacturing liquid fertilizers. The solid-liquid phase equilibria of ternary systems NH4H2PO4 + CO(NH2)2 + H2O, (NH4)2HPO4 + CO(NH2)2 + H2O, K2SO4 + CO(NH2)2 + H2O, K2SO4 + NH4H2PO4 + H2O and K2SO4 + (NH...
In this work, three ionic liquids (ILs), namely monoethanolamine chloride ([HMEA][Cl]), monoethanolamine acetate ([HMEA][OAC]) and 1-ethyl-3-methylimidazole acetate ([EMIM][OAC]), were studied as entrainers to separate acetone+methanol azeotropic mixture by extractive distillation. Isobaric vapor liquid equilibrium of ternary systems containing ILs was investigated to examine the effect between the...
