Description:

4-Chlorophthalic anhydride is a colorless crystalline solid that is soluble in acetone and ethanol. It is used to synthesize dyes, paints, varnishes, and other organic compounds. This compound can be produced by the reaction of copper chloride with chloral hydrate or by the dehydration of phthalic anhydride with concentrated sulfuric acid. 4-Chlorophthalic anhydride reacts with hydrogen chloride to form 4-chlorophthalic acid. The solubility of this compound in water varies depending on the temperature and pH levels. The solubilities of 4-chlorophthalic anhydride are determined using experimental solubility data and calculated using thermodynamic values and vibrational frequencies. Phase equilibrium studies show that at low temperatures, 4-chlorophthalic anhydride is more soluble in water than at higher temperatures due to its lower energy state.
