摘要
葡萄糖、果糖、蔗糖和麦芽糖在0.05 M和0.5 M KCl溶液中,在298.15、303.15、308.15和313.15 K下进行了体积学和粘度学研究。表观摩尔体积(φv)值随KCl溶液浓度的平方根呈线性变化。极限表观摩尔体积(φ 0 v)用溶质-溶剂相互作用来解释。φ 0 v值随温度变化,可以用结构的幂级数表示,通过dB/dT值的符号可以推断电解液的破断能力。测定了表观摩尔膨胀率。葡萄糖、果糖、蔗糖和麦芽糖从摩尔体积和粘度的研究中发现在氯化钾水溶液中是结构的制造者和破坏者。
Study of Structure Making/Breaking Properties of Glucose, Fructose, Sucrose and Maltose in Aqueous KCl at Various Temperatures
The volumetric and viscometric studies of glucose, fructose, sucrose and maltose have been determined in 0.05 M and 0.5 M KCl solutions at 298.15, 303.15, 308.15 and 313.15 K. The apparent molar volume (φv) values vary linearly with square root of concentration of KCl solution. The limiting apparent molar volume (φ 0 v) has been interpreted in terms of solute-solvent interaction. The φ 0 v values vary with temperature and can be represented in the power series of structure making and breaking capacity of electrolyte is inferred from the sign of dB/dT values. The apparent molar expansibility has also been determined. Glucose, fructose, sucrose and maltose have been found to be structure maker and breaker in aqueous KCl from molar volume as well as viscosity studies.
