131-11-3
Product name: Dimethyl Phthalate
English alias: DMP; Phthalic acid dimethyl ester; Methyl phthalate
CAS: 131-11-3
Molecular formula: C10H10O4
Appearance: Colorless to light yellow transparent oily liquid
Package: 200 kg/drum, 1000 kg/IBC tank
Dimethyl Phthalate (DMP) is the simplest and most volatile member of the phthalate ester family, produced by esterification of phthalic anhydride with methanol. It is characterized by its low viscosity, high solvating power, and relatively low boiling point. DMP exhibits good compatibility with a wide range of polymers, including cellulose esters and vinyl resins. While its use as a primary plasticizer has declined due to volatility concerns, it remains valuable in specific applications where its unique properties are advantageous, such as as a solvent and carrier.

Conclusion | qualified | |
1. Dimethyl Phthalate used as a solvent and plasticizer for cellulose acetate in the production of cigarette filters, films, and molded articles.
2. Dimethyl Phthalate employed as a solvent and fixative in perfumery and cosmetic formulations to stabilize fragrances.
3. It applied as a plasticizer and processing aid in polyvinyl acetate (PVAc) adhesives.
4. It used as a carrier for dyes and pigments in various industrial processes.
5. Employed as a chemical intermediate in organic synthesis.
6. Historically used as an insect repellent, particularly against mosquitoes and ticks (largely replaced by more modern agents).
7. Used in specialty coatings and lacquers.
DMP has low acute toxicity but may cause eye and skin irritation. Prolonged or repeated skin contact should be avoided. Use personal protective equipment including gloves and safety glasses. Ensure adequate ventilation. While it is generally less restricted than some higher phthalates like DEHP or DBP, its use in specific applications (e.g., cosmetics, toys) may be regulated. Always consult relevant safety data sheets and local regulations before use.
Acute effects: Inhalation can cause irritation of the eyes, nose, and throat.
Other effects: Direct skin contact may cause mild irritation, and eye contact can result in severe irritation.
Store in a cool, dry, well-ventilated area away from direct sunlight, heat, and ignition sources. Keep containers tightly closed to prevent moisture absorption and evaporation. Recommended storage temperature: 10-40 °C. Store away from strong oxidizing agents, strong acids, and strong bases.
DMP is typically supplied in 200 kg steel or HDPE drums and 1000 kg IBC containers. Classified as non-hazardous for transport in many regions, but specific shipping classification should be verified based on the latest regulations.
