Boiling-temperature measurements have been used to study the kinetics of the decomposition of urea. Values for the rate constants in neutral, acid, and basic media have been obtained and compared with literature data. The effect of the reverse reaction on the value of the experimental rate constants

The relative viscosity data of sodium and potassium halides (concentration range 0.125-3 M) in aqueous urea (1 .O M) solution at the temperature 25", 30", 35" and 40Β°C have been determined. The data have been found to satisfy Moulik's equation, for concentrated solution of the alkali halides beyond
It is suggested, when working with drug-urea-water systems, that more than passing consideration be given to the effect or effects produced by addition of a fourth component, as, for example, when an acid is used to adjust pH. Data are cited which indicate that these effects are measurable and often
The viscosity bahaviour of ternary systems comprising akali halides (concentration range 0.125-3 M) in aqueous N,N' dimethyl urea (0.6 M) solution, over the temperature range 2540Β°C has been investigated. It has been found that Moulik's equation (r&)' = M + KC' holds good for these systems for the c
## Abstract **Summary:** Rapid dissolution of cellulose in LiOH/urea and NaOH/urea aqueous solutions was studied systematically. The dissolution behavior and solubility of cellulose were evaluated by using ^13^C NMR, optical microscopy, wideβangle Xβray diffraction (WAXD), FTβIR spectroscopy, DSC,
