## Abstract It was puzzling that cellulose could be dissolved rapidly in 4.6 wt % LiOH / 15 wt % urea aqueous solution precooled to −12 °C, whereas it could not be dissolved in the same solvent without prior cooling. To clarify this important phenomenon, the structure and physical properties of LiO

## 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, wide‐angle X‐ray diffraction (WAXD), FT‐IR spectroscopy, DSC,
## Abstract Cellulose was dissolved rapidly in 4.6 wt % LiOH/15 wt % urea aqueous solution and precooled to –10 °C to create a colorless transparent solution. ^13^C‐NMR spectrum proved that it is a direct solvent for cellulose rather than a derivative aqueous solution system. The result from transm
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 40°C have been determined. The data have been found to satisfy Moulik's equation, for concentrated solution of the alkali halides beyond
In this work, we present the data on the experimental determination of solubility of gold at T = 30o"C, P = 300 atm, Psat, and pHstart.sol. = 7.4, which was achieved by the addition of NaOH solution with a low concentration. The concentration of HzS varies in a wide range
