💡 Commercial Applications
Dipentyl phthalate, also known as di- n-pentyl phthalate (DPP), is primarily used as a plasticizer in various commercial and industrial applications. It is commonly added to polyvinyl chloride (PVC) to improve its flexibility, durability, and resistance to heat. DPP is used in the production of flexible PVC products such as cables, flooring, wall coverings, and various types of tubing.
In addition to its role as a plasticizer, Dipentyl phthalate has also been explored for its potential applications in the pharmaceutical industry. Some studies have investigated its use as a drug carrier in various formulations due to its low toxicity and biocompatibility. It has shown promise as a potential excipient for drug delivery systems, particularly in oral and transdermal formulations. However, further research is needed to fully explore its potential in drug and medication applications.
⚗️ Chemical & Physical Properties
Dipentyl phthalate is a colorless liquid with a faint, sweet odor. It is commonly used as a plasticizer in various industries due to its ability to increase the flexibility of materials.
With a molar mass of approximately 278.35 g/mol and a density of about 0.98 g/cm3, Dipentyl phthalate is heavier than water but lighter than many common food items such as sugar (molar mass around 342.30 g/mol) and olive oil (density around 0.92 g/cm3).
Dipentyl phthalate has a melting point of around -50°C and a boiling point of about 287°C. These values are higher than those of many common food items such as butter (melting point around 30-35°C) and water (boiling point at 100°C).
Dipentyl phthalate is practically insoluble in water but soluble in organic solvents. It has a relatively low viscosity compared to substances like honey or corn syrup. This makes it easier to mix with other materials in industrial applications.
🏭 Production & Procurement
Dipentyl phthalate, also known as DPP, is produced through the esterification of phthalic anhydride with n-pentanol. This reaction forms the diester, which is then purified through distillation to obtain the final product. The production process must adhere to strict regulatory guidelines to ensure product quality and safety.
Dipentyl phthalate can be procured from chemical suppliers or manufacturers who specialize in producing plasticizers. The compound is typically transported in bulk containers such as drums or tanks to ensure safe handling and storage. It is important to follow proper handling procedures and use appropriate personal protective equipment when working with Dipentyl phthalate.
When procuring Dipentyl phthalate, it is essential to consider factors such as purity, quality, and packaging to meet the specific requirements of the intended application. Suppliers may offer different grades of DPP tailored to various industries, including plastics, coatings, and adhesives. It is crucial to establish a reliable supply chain and ensure proper storage conditions to maintain the integrity of the product.
⚠️ Safety Considerations
Safety considerations for Dipentyl phthalate include the potential for skin and eye irritation upon contact. It is also important to avoid inhalation or ingestion of the substance, as it may lead to respiratory and gastrointestinal discomfort. When handling Dipentyl phthalate, it is recommended to wear appropriate personal protective equipment, such as gloves and goggles, to minimize the risk of exposure.
Hazard statements for Dipentyl phthalate include the substance being harmful if swallowed, causing serious eye irritation, and potentially causing skin irritation. It may also be harmful if inhaled, leading to respiratory irritation. It is important to handle Dipentyl phthalate with caution and to avoid direct contact with the eyes, skin, and respiratory system.
Precautionary statements for Dipentyl phthalate include avoiding ingestion, inhalation, and skin contact. If contact occurs, it is recommended to wash skin thoroughly with soap and water and to seek medical attention if irritation persists. In case of eye contact, rinse eyes cautiously with water for several minutes, removing contact lenses if possible, and seek medical advice. Additionally, it is important to handle Dipentyl phthalate in a well-ventilated area and to store it in a tightly sealed container away from incompatible materials.
🔬 Potential Research Directions
Further research on Dipentyl phthalate (DPeP) could explore its potential health effects, particularly its impact on human reproductive health. Studies could investigate its endocrine-disrupting properties and potential links to conditions such as infertility and hormonal imbalances.
Additionally, research could focus on the environmental implications of DPeP, such as its persistence in the environment and its potential to bioaccumulate in organisms. Studies could investigate its toxic effects on aquatic ecosystems and wildlife, as well as its potential for biomagnification in food chains.
Furthermore, research could examine the sources and pathways of exposure to DPeP in various populations, including vulnerable groups such as pregnant women and children. Studies could assess levels of DPeP in different environmental media, consumer products, and biological samples to better understand the extent of human exposure and potential risks associated with this phthalate.
