The
solubility of l-alanine in five binary systems water
+ methanol, water + ethanol, water + 1-propanol, water + 2-propanol,
and water + acetone and 12 neat solvents (water, 1-butanol, methanol,
2-butanol, 2-methyl-1-propanol, 1-pentanol, 1-propanol, ethanol, 2-propanol,
ethyl acetate, acetonitrile, and acetone) was determined by the gravimetrical
method within the temperature range from 283.15 to 323.15 K under
atmospheric pressure. The experimental results indicated that the
solubility increased with increasing temperature and mole ratio of
water in all investigated solvents and decreased with the rise of
the mole fraction of five different organic solvents in the binary
solvent systems. The order of l-alanine solubility in the
selected pure solvents was water > 1-butanol > methanol ≈
2-butanol
> 2-methyl-1-propanol ≈ 1-pentanol ≈ 1-propanol ≈
ethanol > 2-propanol > ethyl acetate > acetonitrile >
acetone. The
solubility was mathematically represented by the modified Apelblat,
Jouyban–Acree, and Apelblat–Jouyban–Acree models.
All the models can be found to agree well with the data in the experiment.
