Glycol Ethers, High-Purity Solvents

Diethylene Glycol Diethyl Ether Diethylene

Diethylene Glycol Diethyl Ether, often referred to by the acronym DGDE or diethyl carbitol, is a high-boiling, clear, colorless liquid characterized by its mild, pleasant odor and exceptional chemical stability. With the CAS registry number 112-36-7, this ether-based solvent is known for its ability to dissolve a wide range of organic substances, including oils, resins, and nitrocellulose. It belongs to the glycol ether family, which combines the properties of ethers and alcohols. DGDE is particularly valued in industrial chemistry for its high boiling point and low volatility, making it an ideal choice for processes requiring thermal stability and slow evaporation rates. It is miscible with water and common organic solvents, facilitating its use in complex formulations. In addition to its solvent capabilities, it serves as a versatile reaction medium in organic synthesis, notably in Grignard reactions and other organometallic processes where a stable, non-reactive polar solvent is necessary for success.
