Octadecane(Cas 593-45-3) Usage

Description	Octadecane (C₁₈H₃₈) is a straight-chain alkane hydrocarbon with 18 carbon atoms. It is a colorless liquid or solid at room temperature, depending on conditions, and is known for its non-reactive nature under standard conditions. Octadecane is primarily used as a phase-change material, lubricant, chemical intermediate, and solvent in industrial and research settings. Shanghai Wibson Biotechnology Co., Ltd. is a high-tech enterprise that mainly develops and sells pharmaceutical and chemical raw materials and other related products. The company has advanced and perfect supporting system and has formed advanced chemical synthesis technology, which can quickly meet the personalized needs and series development from suitable testing to industrial production. Products are exported to Russia, Southeast Asia and other countries, in the world has a very high reputation and visibility. The company has strong financial strength and a good operating environment, can provide customers with high-quality, efficient and fast services.
Uses	Octadecane is a saturated hydrocarbon (alkane) used in various applications such as solvents, lubricants, and phase-change materials. It falls into the category of long-chain alkanes. Octadecane is used as a non-polar solvent in organic synthesis, owing to its stability and low reactivity. It can dissolve various organic substances, making it useful in lab and industrial settings.
Physical State	Colorless liquid or solid (depending on temperature).
Phase Change	Octadecane exhibits phase changes around 29–30°C, making it useful in thermal energy storage applications.
Definition	ChEBI: A straight-chain alkane carrying 18 carbon atoms.
Combustible	As a hydrocarbon, octadecane is combustible, and care must be taken to avoid ignition in environments where strong oxidizers or open flames are present.

Microencapsulation of octadecane as a phase-change material by interfacial polymerization in an emulsion system

Jeong-Sook Cho, Aehwa Kwon & Chang-Gi Cho

, Colloid and Polymer Science, Volume 280, pages 260–266, (2002)

TDI was reacted with DETA in the weight ratio of 3:1. NP-10 was reacted with TDI to form urethane. The microcapsules containing octadecane showed a phase change of octadecane at 29–30 °C. The core content measured using the heat of fusion of octadecane was less than that calculated. The efficiency of octadecane encapsulation increased as the core content decreased.

Effect of a Pseudomonas rhamnolipid biosurfactant on cell hydrophobicity and biodegradation of octadecane

Y Zhang, R M Miller

, Applied and environmental microbiology, 1994

In this study, the effect of a purified rhamnolipid biosurfactant on the hydrophobicity of octadecane-degrading cells was investigated to determine whether differences in rates of octadecane biodegradation resulting from the addition of rhamnolipid to four strains of Pseudomonas aeruginosa could be related to measured differences in hydrophobicity.
