💡 Commercial Applications
Benzyl butyl phthalate, a chemical compound commonly abbreviated as BBP, finds various commercial and industrial applications due to its properties. It is commonly utilized as a plasticizer in the manufacturing of vinyl flooring, automotive parts, and other flexible PVC products. BBP helps improve the flexibility, durability, and resilience of these materials, making it a popular choice for such applications.
In addition to its commercial and industrial uses, Benzyl butyl phthalate also has applications in the pharmaceutical industry. BBP is sometimes utilized as an excipient in the formulation of certain drug products, where it serves as a solvent or plasticizer. Its ability to improve the solubility of active pharmaceutical ingredients and enhance the stability of drug formulations makes it a valuable component in certain medications.
Furthermore, Benzyl butyl phthalate has been employed in the development of medical devices and equipment. BBP is included in the production of certain medical-grade plastics and polymers used in devices such as catheters, IV tubing, and blood bags. Its plasticizing properties help ensure the flexibility and performance of these medical products, contributing to their safe and effective use in healthcare settings.
⚗️ Chemical & Physical Properties
Benzyl butyl phthalate, a colorless oily liquid, possesses a faint sweet aromatic odor recognizable at low concentrations.
With a molar mass of 312.39 g/mol and a density of 1.124 g/cm³, benzyl butyl phthalate displays characteristics similar to common food items such as cooking oil, which also typically have similar molar masses and densities.
The melting point of benzyl butyl phthalate is around -35°C, while the boiling point is approximately 325°C. By comparison, common food items like butter have lower melting points and boiling points.
Benzyl butyl phthalate is sparingly soluble in water and has a relatively low viscosity, similar to vegetable oils. On the other hand, common food items like sugar exhibit high water solubility and low viscosity.
🏭 Production & Procurement
Benzyl butyl phthalate is produced through the esterification reaction between phthalic anhydride and a mixture of butanol and benzyl alcohol. This reaction is typically carried out under controlled conditions of temperature and pressure in the presence of an acid catalyst.
The procurement of Benzyl butyl phthalate involves sourcing the necessary raw materials such as phthalic anhydride, butanol, and benzyl alcohol from chemical suppliers. These materials are then combined in the required proportions and subjected to the esterification reaction to produce the final product.
Once Benzyl butyl phthalate is produced, it can be transported in bulk quantities using tanker trucks or rail cars. The product is typically stored and transported in carefully sealed containers to prevent contamination and ensure its integrity during transit. Specialized chemical handling procedures are usually followed to ensure safe and reliable transportation of the compound.
⚠️ Safety Considerations
Safety considerations for Benzyl butyl phthalate must be carefully adhered to in order to prevent potential health risks associated with its use. When handling this chemical, it is crucial to wear appropriate personal protective equipment such as gloves, goggles, and a lab coat to avoid direct contact with the skin, eyes, or clothing. Benzyl butyl phthalate should be stored in a well-ventilated area away from sources of ignition and incompatible materials to prevent accidental fires or chemical reactions.
Additionally, it is important to follow proper disposal procedures for Benzyl butyl phthalate to avoid environmental contamination. This chemical should not be released into the environment or poured down the drain, as it can pose a risk to aquatic life and ecosystems. Proper labeling and containment of Benzyl butyl phthalate containers is essential to minimize the potential for spills or leaks that could endanger human health and the environment.
In summary, Benzyl butyl phthalate presents several safety considerations that must be taken into account when handling, storing, and disposing of this chemical to ensure the protection of both individuals and the environment.
Hazard statements for Benzyl butyl phthalate include the following: “May cause respiratory irritation”, “Suspected of damaging fertility or the unborn child”, and “May cause harm to breastfed children”. These hazard statements indicate the potential risks associated with exposure to Benzyl butyl phthalate, highlighting the importance of using proper safety measures and precautions when handling this chemical.
Precautionary statements for Benzyl butyl phthalate include: “Avoid breathing dust/fume/gas/mist/vapors/spray”, “Use only outdoors or in a well-ventilated area”, and “Wear protective gloves/eye protection/face protection”. These precautionary statements serve as guidelines for safe handling of Benzyl butyl phthalate and emphasize the importance of minimizing exposure to this chemical to reduce the risk of adverse health effects. It is important to follow these precautions to protect oneself and others from potential harm when working with Benzyl butyl phthalate.
🔬 Potential Research Directions
One potential research direction for Benzyl butyl phthalate (BBP) could involve investigating its effects on human health, particularly its potential for reproductive toxicity and endocrine disruption. Understanding the mechanisms by which BBP interacts with the body’s hormonal systems could provide valuable insights into its potential risks and inform regulatory decisions.
Another avenue for research could focus on the environmental impact of BBP, including its persistence in the environment, potential for bioaccumulation in ecosystems, and effects on wildlife. Studying the long-term effects of BBP exposure on various organisms could help assess its overall ecological risk and guide mitigation strategies.
Furthermore, research could explore alternative compounds or technologies to replace BBP in various industrial applications, such as plasticizers in consumer products. Developing safer and more sustainable alternatives to BBP could help reduce its potential adverse effects on human health and the environment, while still meeting the needs of various industries.
🧪 Related Compounds
One similar compound to Benzyl butyl phthalate based upon molecular structure is Butyl benzyl phthalate. This compound has the benzyl group and the butyl group connected to the phthalate backbone in a similar manner to Benzyl butyl phthalate. However, in Butyl benzyl phthalate, the positions of the benzyl and butyl groups are reversed, with the benzyl group attached to the central carbon atom of the phthalate backbone, while the butyl group is attached to one of the terminal carbon atoms.
Another similar compound to Benzyl butyl phthalate is Diethylhexyl phthalate. In this compound, two ethylhexyl groups are attached to the phthalate backbone instead of the benzyl and butyl groups present in Benzyl butyl phthalate. Despite the difference in the specific alkyl groups attached to the phthalate backbone, Diethylhexyl phthalate shares similar characteristics with Benzyl butyl phthalate due to the presence of alkyl chains of comparable length.
Diallyl phthalate is also a compound similar to Benzyl butyl phthalate in terms of molecular structure. In this compound, two allyl groups are connected to the phthalate backbone, differing from the benzyl and butyl groups found in Benzyl butyl phthalate. Despite the variation in the specific functional groups attached to the phthalate backbone, Diallyl phthalate exhibits similarities to Benzyl butyl phthalate due to the presence of unsaturated carbon-carbon bonds in the alkyl chains.
