Butyl Carbitol

Butyl Carbitol is a solvent and cleaning agent commonly used in industrial and consumer applications. It is the common name for 2-butoxyethanol, a member of the glycol ether family. Its chemical formula is C₆H₁₄O₂.

Butyl Carbitol is a colorless, odorless, and mildly sweet-smelling liquid that has excellent solvency properties, making it highly versatile in many sectors, including coatings, cleaning, agriculture, and manufacturing.

Properties of Butyl Carbitol:

  • Molecular Formula: C₆H₁₄O₂ (also written as CH₃(CH₂)₄OCH₂CH₂OH).
  • Molar Mass: 118.18 g/mol
  • CAS Number: 112-34-5
  • Functional Group: Butyl Carbitol contains both an ether group (–O–) and an alcohol group (–OH), making it a glycol ether with a hydrophilic and hydrophobic structure.
  • Reactivity:
    • Butyl Carbitol is chemically stable under normal conditions but may react with strong acids and strong bases.
    • It can be slowly hydrolyzed to form butyl alcohol and ethylene glycol under basic conditions.
    • It does not typically participate in highly reactive chemical reactions in its normal state.
  • Appearance: A colorless to slightly yellow liquid.
  • Odor: Mildly sweet, almost odorless.
  • Density: 0.90 g/cm³ at 20°C.
  • Melting Point: –75°C (–103°F).
  • Boiling Point: 171°C (340°F).
  • Viscosity: 2.6 cP at 20°C (viscous).
  • Solubility:
    • Miscible in water in varying concentrations and soluble in many organic solvents, including alcohols, esters, ketones, and ethers.
    • Exhibits excellent solvency properties for a wide range of polar and non-polar compounds.

Uses of Butyl Carbitol:

  • Solvent: Used in coatings, paints, and cleaning products.
  • Textiles: Used in the textile industry for dyeing and finishing fabrics.
  • Agriculture: Used as a solvent for herbicides and pesticides.
