Overview
Perfluorobutanol (PFB) is a fluorinated organic compound belonging to the family of fluorinated alcohols. It is characterized by its fully fluorinated carbon chain, which imparts unique properties such as high chemical stability and low surface tension. PFB is primarily used in industrial applications where these properties are advantageous. In the chemical industry, PFB serves as a versatile intermediate for synthesizing fluorinated surfactants and coatings. Its ability to repel water and oils makes it valuable in formulations requiring hydrophobic or oleophobic characteristics. Despite its niche applications, PFB is not as widely produced as other fluorochemicals, making it a specialty chemical.
Physical and Chemical Properties
Perfluorobutanol is a colorless liquid with a density of 1.68 g/cm³, significantly higher than water. It exhibits a boiling point of approximately 98°C, making it relatively volatile compared to other fluorinated compounds. The molecular structure, featuring a perfluorinated butyl group, contributes to its chemical inertness and resistance to degradation. One of the standout properties of PFB is its low surface tension, which is beneficial in applications like coatings and surfactants. It is soluble in common organic solvents but immiscible with water, a trait typical of highly fluorinated compounds. These properties make PFB suitable for specialized formulations where traditional alcohols fail to meet performance requirements.
Main Applications
Perfluorobutanol is predominantly used in the production of fluorinated surfactants and coatings. Its ability to lower surface tension and repel both water and oils makes it ideal for applications in firefighting foams, stain-resistant fabrics, and anti-fogging agents. PFB is also employed as a solvent or intermediate in the synthesis of more complex fluorinated compounds. In the electronics industry, PFB finds use in the formulation of specialty cleaning agents for delicate components. Its chemical stability ensures it does not react with sensitive materials, making it a preferred choice for precision cleaning. Additionally, PFB is explored in pharmaceutical research for its potential in drug delivery systems due to its biocompatibility at low concentrations.
Safety and Storage
While Perfluorobutanol is not classified as highly hazardous, proper handling is essential to minimize risks. It should be stored in a cool, dry place away from oxidizing agents and direct sunlight. Containers must be tightly sealed to prevent evaporation and contamination. Personal protective equipment (PPE), including gloves and safety goggles, is recommended when handling PFB. Although it has low acute toxicity, prolonged exposure should be avoided. In case of spills, absorb the material with an inert substance and dispose of it according to local regulations. Ventilation is crucial to prevent the accumulation of vapors in confined spaces.
B2B Procurement Guide
When procuring Perfluorobutanol, buyers should prioritize suppliers with a proven track record in fluorochemicals. Key considerations include verifying the CAS number (375-01-9) and requesting certificates of analysis to confirm purity levels, which typically range from 95% to 99%. Bulk purchases often attract discounts, so it's advisable to negotiate pricing based on volume. Logistics planning is critical due to PFB's relatively low boiling point; ensure transportation and storage conditions are controlled to prevent degradation. Lead times can vary, so early engagement with suppliers is recommended to secure inventory for time-sensitive projects.
