⚗️ Chemical & Physical Properties
Quinoline is a colorless to yellowish liquid with a distinctive, pungent odor. It is often described as having a slightly unpleasant odor similar to that of coal tar.
With a molar mass of 129.16 g/mol and a density of 1.093 g/cm3, quinoline falls within the range of common household items in terms of molar mass and density. For comparison, water has a molar mass of 18.02 g/mol and a density of 1 g/cm3.
Quinoline has a melting point of 0.5°C and a boiling point of 237°C. These values are higher compared to common household items like water (melting point of 0°C and boiling point of 100°C), indicating a higher level of thermal stability.
Quinoline is poorly soluble in water, but it is miscible in most organic solvents. It has a relatively low viscosity, making it less viscous than common household items like honey or maple syrup.
🏭 Production & Procurement
Quinoline is produced through the process of distillation of coal tar or through the reaction of aniline with acetaldehyde in the presence of sulfuric acid. The resulting crude Quinoline is then further purified and refined through a series of distillation and crystallization processes to obtain the final product.
Quinoline can be procured from chemical manufacturers or suppliers who specialize in the production and distribution of aromatic compounds. It is typically transported in liquid form in sealed containers or barrels to prevent contamination or leakage during transit. Specialized storage and handling procedures may be required due to its flammable nature.
Large quantities of Quinoline may be transported via tanker trucks or railcars to industrial facilities where it is used in the production of various chemicals, pharmaceuticals, and dyes. Strict adherence to safety regulations and guidelines is essential to prevent accidents and ensure the safe handling and transportation of Quinoline. Careful planning and coordination with logistics providers are necessary to ensure timely and efficient delivery to end-users.
⚠️ Safety Considerations
Safety considerations for Quinoline revolve around its potential hazards as a chemical compound. Quinoline is highly flammable and should be stored away from ignition sources. When handling Quinoline, proper personal protective equipment such as gloves, goggles, and lab coats should be worn to prevent skin contact and inhalation of fumes. In case of a spill, it is important to clean it up promptly and safely to avoid any accidents.
The pharmacology of Quinoline involves its role as a heterocyclic compound with diverse biological activities. Quinoline has been studied for its antimalarial, antitumor, and antibacterial properties. It can also act as a ligand for various receptors in the body, leading to potential therapeutic applications in drug development.
Hazard statements for Quinoline include its classification as a flammable liquid and toxic substance. Quinoline may cause skin irritation and serious eye damage upon contact. Prolonged or repeated exposure to Quinoline may lead to respiratory irritation and central nervous system effects. It is important to handle Quinoline with caution and follow proper safety protocols to minimize risks.
Precautionary statements for Quinoline involve measures to ensure safe handling and storage of the chemical. It is recommended to keep Quinoline in a well-ventilated area and away from heat sources. Avoid skin contact and inhalation of vapors by using appropriate protective gear and working in a fume hood. In case of ingestion or exposure, seek medical attention immediately and provide the relevant information about the chemical involved.
