For professionals in the chemical industry, a deep understanding of a compound's synthesis and properties is fundamental to effective procurement and application. Dimethyl Phthalate (DMP), identified by CAS number 131-11-3, is a compound whose chemical characteristics lend themselves to diverse industrial uses. This article explores its synthesis pathway and key physical and chemical properties, providing valuable insights for those looking to buy DMP from reliable manufacturers.

Dimethyl Phthalate is an organic compound belonging to the phthalate ester family, with the chemical formula C10H10O4 and a molecular weight of approximately 194.19 g/mol. It is commercially synthesized through the esterification of phthalic anhydride with methanol. This reaction is typically catalyzed by a strong acid, such as sulfuric acid, or by Lewis acids like titanium or zirconium complexes. The process involves reacting phthalic anhydride with an excess of methanol to ensure complete conversion, followed by the removal of unreacted methanol via distillation. This method ensures a high yield and purity of the final Dimethyl Phthalate product.

Physically, DMP presents as a clear, oily liquid. Key properties that are important for industrial applications include its density, which is around 1.175 g/cm³, and its relatively high boiling point of 282.7 °C at standard atmospheric pressure. Its flash point is 146.7 °C, classifying it as a combustible liquid. While it has limited solubility in water (about 0.4% at 20°C), it is readily soluble in many organic solvents such as benzene and acetone. These properties dictate its handling, storage, and application suitability.
