💡 Commercial Applications

Octadecane, also known as n-octadecane or CH3(CH2)16CH3, is a straight-chain alkane with multiple commercial and industrial applications. It is commonly used as a phase change material in thermal energy storage systems due to its high latent heat of fusion. Octadecane is also utilized as a lubricant and a component in manufacturing processes for products such as candles, crayons, and coatings.

In terms of drug and medication applications, octadecane has been studied for its potential as a drug delivery agent. Its ability to encapsulate and release pharmaceutical compounds in a controlled manner makes it a promising candidate for targeted drug delivery systems. Additionally, octadecane has been explored for its antimicrobial properties and its potential use in antimicrobial coatings for medical devices and surfaces in healthcare settings.

⚗️ Chemical & Physical Properties

Octadecane, also known as n-octadecane, is a straight-chain alkane with the chemical formula C18H38. It is a colorless, odorless solid at room temperature, resembling white crystalline flakes or powder. Due to its lack of odor, octadecane is often used in various industrial applications where an odorless substance is required.

The molar mass of octadecane is approximately 254.50 g/mol, with a density of 0.778 g/cm³ at 25°C. Compared to common household items, octadecane has a higher molar mass than substances like water (18.02 g/mol) and ethanol (46.07 g/mol). However, it has a lower density than water (1 g/cm³) and ethanol (0.789 g/cm³).

Octadecane has a relatively high melting point of 28.2°C and a boiling point of 316.4°C. In comparison to common household items, octadecane has a higher melting point than substances like butter (32-35°C) and paraffin wax (47°C). Its boiling point is also higher than those of water (100°C) and ethanol (78.37°C).

Octadecane is insoluble in water, but it is soluble in organic solvents such as hexane and methanol. It has a relatively high viscosity due to its long hydrocarbon chain. In comparison to common household items, octadecane has low solubility in water, unlike substances like salt and sugar. Additionally, its viscosity is higher than that of water and alcohol.

🏭 Production & Procurement

Octadecane, a hydrocarbon compound with the chemical formula C18H38, is primarily produced through the process of catalytic hydrogenation of olefins or by the hydroformylation of alkenes. These methods involve the conversion of unsaturated hydrocarbons into saturated hydrocarbons by adding hydrogen or carbon monoxide, respectively.

Once Octadecane is produced, it can be obtained through various means of procurement. This includes purchasing from chemical suppliers who specialize in hydrocarbon compounds or directly from manufacturers who produce Octadecane on a commercial scale. The transportation of Octadecane typically occurs in liquid form, either through bulk tanker trucks or railcars, in order to ensure safe and efficient delivery to end users.

In the realm of industrial applications, Octadecane plays a significant role as a component in various products such as lubricants, fuels, and plastics. Due to its high melting point and low volatility, Octadecane is particularly valued for its stability and heat resistance in these applications. Additionally, its availability for procurement in bulk quantities makes it a viable option for industries requiring a reliable source of saturated hydrocarbons.
