💡 Commercial Applications
Biphenyl, a white crystalline compound, is widely used in various commercial and industrial applications. It is commonly utilized as a heat transfer medium in liquid phase heat exchange systems due to its high thermal stability and low viscosity. Additionally, biphenyl is used in the manufacturing of pesticides, plastics, and as a precursor in the synthesis of dyes and fragrances.
In drug and medication applications, biphenyl has been known for its potential therapeutic properties. It has been researched for its anti-inflammatory and antioxidant effects, as well as its ability to inhibit the growth of certain cancer cells. Biphenyl derivatives have also shown promise in the treatment of various diseases, including diabetes and neurodegenerative disorders. Further studies are ongoing to explore the full potential of biphenyl in the field of medicine.
⚗️ Chemical & Physical Properties
Biphenyl is a white crystalline solid with a distinctive odor often described as musty or mothball-like. It has a molecular formula of C12H10 and a molar mass of 154.21 g/mol. The density of biphenyl is approximately 1.15 g/cm3. In comparison to common household items, biphenyl has a higher molar mass than water (18.02 g/mol) and air (approximately 28.97 g/mol), but a lower density than most metals and minerals.
Biphenyl has a melting point of 69.2°C and a boiling point of 255°C. These temperatures are relatively high compared to common household items such as water (with a melting point of 0°C and a boiling point of 100°C). However, biphenyl’s melting and boiling points are lower than those of materials like iron or aluminum. The high melting and boiling points of biphenyl indicate its stability under typical environmental conditions.
Biphenyl is insoluble in water, but soluble in many organic solvents such as benzene and ethanol. It has a low viscosity, meaning it flows easily. In comparison to common household items, biphenyl’s solubility in water is similar to substances like oil or grease, while its low viscosity is akin to that of non-polar liquids. The solubility and viscosity properties of biphenyl make it useful for various industrial applications.
🏭 Production & Procurement
Biphenyl, a white crystalline solid with a molecular formula of C12H10, is primarily produced through the process of catalytic dehydrogenation of benzene. This reaction involves the use of a catalyst, such as copper or iron, to remove hydrogen atoms from benzene molecules, resulting in the formation of biphenyl.
Once produced, biphenyl can be procured from chemical manufacturers or specialty suppliers who distribute the compound in various forms, such as powder or crystal. The transportation of biphenyl typically involves the use of sealed containers or drums to prevent contamination or leakage during transit.
In industries where biphenyl is used as a heat transfer fluid or as a precursor for the production of other chemicals, bulk quantities of the compound may be transported via tank trucks or railcars to manufacturing facilities. It is vital to follow proper safety protocols during the transportation and handling of biphenyl to prevent any hazards or environmental risks.
⚠️ Safety Considerations
Safety considerations for Biphenyl include its potential for eye and skin irritation upon contact, as well as respiratory irritation if inhaled. It is important to handle Biphenyl with care, avoiding prolonged or repeated exposure to the substance. Personal protective equipment such as gloves, goggles, and a respirator should be worn when working with Biphenyl to minimize risk of any adverse effects.
Biphenyl is a white, flaky solid that is chemically stable and insoluble in water. It is primarily used as a heat transfer medium in various industrial processes and as a precursor in the production of dyes and pharmaceuticals. When ingested or inhaled, Biphenyl is metabolized by the liver and excreted through the urine. Its pharmacological properties include low acute toxicity levels in humans, with symptoms of exposure typically limited to irritation of the eyes, skin, and respiratory system.
Hazard statements for Biphenyl include its classification as an irritant to the skin, eyes, and respiratory system. Prolonged or repeated exposure may cause dermatitis or irritation of the mucous membranes. In case of contact with skin or eyes, thorough washing with water is recommended to remove the substance. Inhalation of Biphenyl vapors should be avoided, as it may cause respiratory irritation.
Precautionary statements for Biphenyl involve measures to minimize exposure and prevent adverse effects. It is important to handle the substance in a well-ventilated area to reduce the risk of inhalation. Personal protective equipment, such as gloves, goggles, and a respirator, should be worn when working with Biphenyl. In case of spills or leaks, proper cleanup procedures should be followed to contain the substance and prevent environmental contamination.
🔬 Potential Research Directions
One potential research direction for biphenyl is its role as a precursor in the synthesis of various organic compounds. Investigating new synthetic routes and optimizing reaction conditions could lead to the development of novel materials or pharmaceuticals.
Another area of interest is the environmental impact of biphenyl and its derivatives. Research could focus on studying their persistence and potential toxicity in ecosystems, as well as developing methods for their remediation or degradation.
