ABSTRACT

The propanoic acid 3-(hydroxyphenylphosphinyl)-monosodium salt (HPPS) and disodium salt (SHPPS) particles as most important flame retardants were synthesized by 3-(hydroxyphenylphosphinyl)- propanoic acid with sodium hydrogen carbonate at room-temperature and characterized. The solubility of HPPS and SHPPS in pure water, methanol, ethanol, acetone, acetic acid and ethyl acetate were measured over a temperature range from 293.15 to 343.15 K under atmospheric pressure. Furthermore, the solubility of HPPS in mixed waters (ethanol + water) was determined and found to exhibit a synergistic effect. The two models, including the modified Apelblat model and the Scatchard Hildebrand model were applied to correlate the experimental solubility data. The calculated solubilities are in good agreement with the experimental results.
