Overview

1-Butoxybutane (CAS 142-96-1) is a dibutyl ether solvent with excellent solvating properties and moderate volatility for industrial applications. 1-Butoxybutane, also known by its IUPAC name 1-butoxybutane, is a symmetrical ether compound with the molecular formula C8H18O and a molecular weight of 130.23 g/mol. This colorless liquid belongs to the family of aliphatic ethers and serves as an important industrial solvent in various chemical processes. The compound exhibits typical ether characteristics, including good chemical stability under normal conditions and excellent dissolving capabilities for a wide range of organic substances. From a safety perspective, 1-butoxybutane is classified as a flammable liquid (Category 3) and requires appropriate handling precautions. The substance carries GHS02 and GHS07 pictograms with a "Warning" signal word, indicating potential for skin and eye irritation as well as specific target organ toxicity following single exposure. Its ADR classification as Class 3 confirms its flammable nature, necessitating proper storage and transportation protocols in accordance with dangerous goods regulations. The compound finds application primarily as a solvent in industrial formulations, particularly in coating systems and chemical synthesis processes where its moderate evaporation rate and good solvating power are advantageous. It also serves in extraction processes and as a reaction medium in organic chemistry applications. Unlike more volatile solvents such as 4-methoxy-4-methylpentan-2-one, 1-butoxybutane offers extended working time due to its lower volatility, making it suitable for applications requiring longer open times. OYSI supplies 1-butoxybutane to meet diverse industrial requirements across Europe, ensuring consistent quality and reliable delivery for technical applications.

Frequently Asked Questions

What is 1-butoxybutane?

1-butoxybutane is an organic chemical compound with the molecular formula C8H18O and CAS number 142-96-1. It belongs to the ether family and has a molecular weight of 130.23 g/mol. This substance is classified as a flammable liquid and can cause skin and eye irritation. It also presents potential risks for specific target organ toxicity and aquatic environments, making proper handling and safety measures essential for industrial applications.

What are the physicochemical properties of 1-butoxybutane?

1-butoxybutane is a liquid ether compound at room temperature with the molecular formula C8H18O. As an ether with a relatively long carbon chain, it exhibits moderate volatility and limited water solubility due to its hydrophobic nature. The compound has a molecular weight of 130.23 g/mol and demonstrates typical ether characteristics including flammability. Its physical properties make it suitable for various industrial solvent applications where controlled evaporation rates are desired.

What is 1-butoxybutane used for?

1-butoxybutane serves primarily as an industrial solvent due to its ether properties and moderate volatility. It is commonly used in formulations requiring controlled evaporation rates and good solvency for organic compounds. Applications include paint and coating industries, cleaning formulations, and as a process solvent in chemical manufacturing. Its balanced properties between volatility and solvency make it valuable for applications where traditional solvents may be too aggressive or too slow to evaporate.

How to handle 1-butoxybutane safely?

1-butoxybutane requires careful handling due to its flammable nature and irritant properties. Essential safety measures include wearing appropriate personal protective equipment such as chemical-resistant gloves, safety goggles, and protective clothing to prevent skin and eye contact. Work in well-ventilated areas or use local exhaust ventilation to minimize inhalation exposure. Keep away from ignition sources, hot surfaces, and oxidizing agents. Ensure proper grounding and bonding during transfer operations to prevent static electricity buildup.

How to store 1-butoxybutane correctly?

1-butoxybutane must be stored in a cool, dry, well-ventilated area away from heat sources, sparks, and open flames due to its Class 3 flammable liquid classification. Use appropriate containers made of compatible materials and ensure proper labeling with GHS pictograms GHS02 and GHS07. Store away from oxidizing agents and incompatible materials. Maintain temperatures below flash point and implement proper fire prevention measures including appropriate fire suppression systems in storage areas.
