ZhonghanPhysical properties

Phthalic acid appears as a white crystalline powder at room temperature, which is odorless and has a light sour taste. Its melting point is about 207°C, at which temperature it changes from solid to liquid. Its density is about 1.593g/cm³. In terms of solubility, phthalic acid is slightly soluble in cold water, with only about 0.5 grams of phthalic acid being dissolved in every 100 ml of cold water; but it is easily soluble in hot water, and its solubility in hot water is significantly improved; at the same time, it also has good solubility in ethanol and ether, and can be fully mixed with these organic solvents to meet the needs of different chemical reaction systems and industrial applications.

ZhonghanApplication Areas

Phthalic acid has a wide range of applications. In the plastics industry, it is a key raw material for the production of phthalate plasticizers, which can give plastic products good flexibility, plasticity and durability. They are often used to make films, pipes, artificial leather, plastic toys and other products. In the field of coatings, phthalic acid participates in the synthesis of alkyd resins, effectively improving the film-forming properties, glossiness and corrosion resistance of coatings. It is widely used in surface coatings of furniture, automobiles, buildings, etc. In the pharmaceutical industry, phthalic acid can be used to synthesize certain drug intermediates to provide support for drug research and development and production. In addition, it also plays an important role in dye production, helping to synthesize various brightly colored and stable dyes.
