“…4-CPA is usually used to prevent falling flowers and fruits, promote early maturity, and improve the quality of plants. For these reasons, it is commonly used as a plant growth regulator for tomatoes, bean sprouts, and other vegetables. − Also, it serves as the pharmaceutical intermediate of meclofenoxate, which is used as a central nervous stimulant for consciousness disorder and traumatic coma . Also, 4-CPA has been proved to be used to prepare biofilms with strong ion-exchange capacity (IEC) and proton conductivity.…”

The solubility of 4-chlorophenoxyacetic acid (4-CPA) in 13 monosolvents including ethanol, 1-propanol, isopropanol, 1-butanol, 2-butanol, isobutanol, ethyl formate, methyl acetate, ethyl acetate, propyl acetate, butyl acetate, acetonitrile, and 1,4-dioxane was measured by a gravimetric method from 283.15 to 328.15 K at an atmospheric pressure of 0.1013 MPa. The solubility of 4-CPA increased with temperature and followed the order 1,4-dioxane > alcohols > esters > acetonitrile at all experimental temperatures. The solvent effects, especially solvent polarity, hydrogen bond donor propensity, and hydrogen bond acceptor propensity, were used to analyze the solubility of 4-CPA in different solvents. The solubility basically follows the rule "like dissolves like" and has a higher value in solvents with strong hydrogen bond donor propensity and hydrogen bond acceptor propensity. Besides, the modified Apelblat equation, λh equation, and van't Hoff equation were applied to correlate the measured solubility data. The average relative deviation (ARD) values showed that the correlation results of the three models agree well with the experimental data.
