The density of aqueous acetamide solutions was measured over the temperature range 25-85 C. From the obtained density data apparent molal volume of acetamide in water and volume expansibility coefficient were calculated. The analysis of changes of these functions in relation to acetamide concentration and temperature allowed to conclude on breaking effect of acetamide on water structure.
PL
Zmierzono gęstość wodnych roztworów acetamidu w zakresie temp. 25-85 C. Na podstawie otrzymanych badanych gęstości obliczono wartości pozornej molowej objętości acetamidu w wodzie oraz współczynnik rozszerzalności objętościowej danych roztworów. Analiza zmian wymienionych wielkości w zależności od stężenia acetamidu i temperatury pozwoliła wysnuć wniosek o niszczącym wpływie acetamidu na strukturę wody.

Kinetics of the reaction of thiourea with methyl iodide in aqueous solutions at the temperatures 25°, 35° and 40°C has been investigated. The reaction was found to be dimolecular. The rate of the reaction is not affected by pH of solution with in the range 4.00 - 9.06. Activation energy of the reactions is 74.07 KJ/mole K.
PL
Badano kinetykę reakcji tiomocznika z jodkiem metylu w roztworach wodnych w temperaturze 25°, 35° and 40°C. Stwierdzono, że jest to reakcja dwucząsteczkowa. Na szybkość reakcji nie wpływa pH roztworu w zakresie 4.00 - 9.06. Energia aktywacji reakcji wynosi 74.07 kJ/mol K.
