Dimethyl Phthalate (DMP), a key organic compound with the CAS number 131-11-3, is synthesized through a well-established chemical process. Understanding its properties and manufacturing is fundamental for R&D professionals and procurement managers seeking to optimize its use. As a leading manufacturer, NINGBO INNO PHARMCHEM CO.,LTD. ensures high-quality DMP is readily available for various industrial needs. This article explores the science behind DMP, from its synthesis to its diverse applications.

The commercial production of Dimethyl Phthalate primarily involves the esterification of phthalic anhydride with methanol. This reaction, often catalyzed by a strong acid like sulfuric acid, or alternative Lewis acids, converts phthalic anhydride into the desired ester. Excess methanol is typically used to drive the reaction to completion, and the unreacted methanol is subsequently removed via distillation. This carefully controlled process results in a colorless, oily liquid with a characteristic slight aromatic odor and a purity assay of 99.5% or higher. For those looking to buy Dimethyl Phthalate, knowledge of its synthesis assures them of its consistent quality.

The molecular structure of DMP, C10H10O4, contributes to its utility. As a short-chain phthalate ester, it exhibits good solvency and compatibility with various polymers. Its primary application as a plasticizer for PVC hinges on its ability to intercalate between polymer chains, increasing chain mobility and thus enhancing flexibility. This property is critical for industries manufacturing products like flexible hoses, cables, and flooring. Buyers often inquire about the Dimethyl Phthalate price, which is influenced by the efficiency and cost-effectiveness of this manufacturing process.

DMP’s versatility extends beyond plastics. It is a recognized insect repellent, effective against mosquitoes and other biting insects, making it a valuable ingredient in consumer products. Its solvent properties also find use in lacquers, coatings, and certain cosmetic formulations. The ability to reliably purchase DMP from a quality-conscious supplier like NINGBO INNO PHARMCHEM CO.,LTD. ensures that these diverse applications are met with a consistent, high-purity product.
