2-Ethylbutanol
Overview
2-Ethylbutanol is an organic alcohol with a branched six-carbon structure. It is classified as a higher alcohol due to its molecular weight and finds use in various industrial applications. As a solvent, it offers balanced properties between volatility and solvency power, making it suitable for coatings, inks, and cleaning formulations. Its production typically involves hydroformylation or aldol condensation processes.
Physical and Chemical Properties
This liquid alcohol demonstrates typical alcohol characteristics with a hydroxyl group that enables hydrogen bonding. The branched ethyl group affects its physical properties, giving it a lower density compared to linear isomers. Chemically, 2-ethylbutanol can undergo reactions common to primary alcohols including esterification, oxidation, and ether formation. Its moderate boiling point makes it useful in applications requiring controlled evaporation rates.
Main Applications
The primary use of 2-ethylbutanol is as an industrial solvent for resins, dyes, and coatings where its evaporation rate and solvency are advantageous. It's particularly valued in cellulose nitrate and vinyl formulations. In chemical manufacturing, it serves as an intermediate for producing plasticizers, lubricant additives, and specialty esters. The fragrance industry utilizes its mild odor characteristics in certain perfume compositions.
Safety and Storage
As a flammable liquid (flash point approximately 46°C), 2-ethylbutanol requires careful handling with appropriate fire prevention measures. Containers should be grounded during transfer to prevent static discharge. Storage should be in approved flammable liquid cabinets or rooms with adequate ventilation. Personnel handling the chemical should use proper PPE including chemical-resistant gloves and eye protection due to its irritant properties.
B2B Procurement Guide
Industrial buyers should specify required purity levels (typically 98-99.5%) and request certificates of analysis. Bulk procurement in ISO tanks or 200L drums generally offers better economics. Quality verification should include checks for water content and impurities. Reliable suppliers should provide proper SDS documentation and comply with regional chemical regulations for transportation and handling.
