Incompatible with strong oxidizing agents and strong acids.
Butyl diglyme (diethylene glycol dibutyl ether) is a high-performance solvent used in digital inks and decorative inks for ceramics. BUTYL DIGLYME (Butyl Diglyme, bütil diglim, Diethylene glycol dibutyl ether, dietilen dibütil eter) is a safe and effective solvent for emissive applications.
BUTYL DIGLYME (Butyl Diglyme, bütil diglim, Diethylene glycol dibutyl ether, dietilen dibütil eter), also called diethylene glycol di-n-butyl ether, is a polar aprotic solvent with excellent thermal and chemical stability. BUTYL DIGLYME (Butyl Diglyme, bütil diglim, Diethylene glycol dibutyl ether, dietilen dibütil eter), or glycol diethers, are a widely used family of saturated polyethers for increasing anion reactivity in a given system, thus affecting selectivity and reaction rates. BUTYL DIGLYME (Butyl Diglyme, bütil diglim, Diethylene glycol dibutyl ether, dietilen dibütil eter) is one of the heavier ethylene oxide based BUTYL DIGLYME (Butyl Diglyme, bütil diglim, Diethylene glycol dibutyl ether, dietilen dibütil eter) available commercially.
Glymes
BUTYL DIGLYME (Butyl Diglyme, bütil diglim, Diethylene glycol dibutyl ether, dietilen dibütil eter), or glymes, are aprotic, saturated polyethers that offer high solvency, high stability in strong bases and moderate stability in acid solutions. BUTYL DIGLYME (Butyl Diglyme, bütil diglim, Diethylene glycol dibutyl ether, dietilen dibütil eter) efficiently solvate cations, increasing anion reactivity, and thus can increase both selectivity and reaction rates. Most BUTYL DIGLYME (Butyl Diglyme, bütil diglim, Diethylene glycol dibutyl ether, dietilen dibütil eter)are water-soluble, but a range of solubility and boiling points are available. The polyether structure produces only weak associations between glyme molecules, and is responsible for the low viscosity and excellent wetting properties of these solvents. A further structural feature of BUTYL DIGLYME (Butyl Diglyme, bütil diglim, Diethylene glycol dibutyl ether, dietilen dibütil eter) that contributes significantly to their usefulness involves the arrangement of oxygen atoms, as ether linkages, at two-carbon intervals. The model of the BUTYL DIGLYME (Butyl Diglyme, bütil diglim, Diethylene glycol dibutyl ether, dietilen dibütil eter) molecule (picture above) illustrates this periodic recurrence of oxygen atoms separated by two carbon atoms. This steric arrangement, analogous to that of crown ethers, gives BUTYL DIGLYME (Butyl Diglyme, bütil diglim, Diethylene glycol dibutyl ether, dietilen dibütil eter) the ability to form complexes with many cations. Glycol diethers have a wide range of solubilities and boiling points. They are used as reaction solvents and in closed loop applications such as gas scrubbing and in refrigeration systems. The higher molecular weight BUTYL DIGLYME (Butyl Diglyme, bütil diglim, Diethylene glycol dibutyl ether, dietilen dibütil eter) beginning with ethyl diglyme are suitable for emissive applications such as coatings, inks, adhesives and in cleaning compounds. The lower molecular weight BUTYL DIGLYME (Butyl Diglyme, bütil diglim, Diethylene glycol dibutyl ether, dietilen dibütil eter) should not be used in emissive applications due to their reproductive toxicity.

APPLICATIONS of BUTYL DIGLYME (Butyl Diglyme, bütil diglim, Diethylene glycol dibutyl ether, dietilen dibütil eter)
Glycol ethers, with the combination of ether, alcohol and hydrocarbon chain in one molecule, provide versatile solvency characteristics with both polar and non-polar properties. The chemical structure of long hydrocarbon chain resist to solubility in water, while ether or alcohol groups introduce the promoted hydrophilic solubility performance. This surfactant-like structure provides the compatibility between water and a number of organic solvents, and the ability to couple unlike phases. Glycol ethers are characterized by their wide range of hydrophilic/hydrophobic balances. glycol ethers are used as diluents and levelling agents in the manufacture of paints and baking finishes. Glycol ether series are used in the manufacture of nitrocellulose and combination lacquers. They are used as an additive in brake fluid. They are formulated for dying textiles and leathers and for insecticides and herbicides. They provides performance in cleaners products with oil-water dispersions.
