Product Description

Product Name	Diethylene Glycol Diethyl Ether (DEGDEE) CAS 112-36-7 \| EC No. 203-963-7 Synonyms: ethyl diglyme, diethyl carbitol, bis(2-ethoxyethyl) ether, 1-ethoxy-2-(2-ethoxyethoxy)ethane
Formula / MW	C₈H₁₈O₃ ((C₂H₅OCH₂CH₂)₂O) / 162.23
Structure
Product Type	High-boiling glycol diether (glyme) solvent. Both ends are capped with ethyl groups, so it has no free hydroxyl: aprotic, low in acidity and moisture, and chemically inert in most formulations and reactions.
Specification	Appearance: colorless clear liquid Assay (GC): ≥ 99.5% Color (APHA): ≤ 15 Water: ≤ 0.05% Acidity (as acetic acid): ≤ 0.01% Peroxide: ≤ 0.005% Boiling point approx. 189 °C; flash point approx. 82 °C (closed cup); density approx. 0.907 g/cm³ at 20 °C (literature) Typical values; the batch COA governs.
Applications	Inkjet and digital printing inks: slow-evaporating co-solvent that reduces nozzle drying and clogging and improves leveling; low acidity protects printheads Electronic cleaning: component of photoresist strippers and flux removers Coatings: flow and leveling aid in high-solids and waterborne paints Chemical synthesis: inert, high-boiling reaction solvent for Grignard and other organometallic reactions
Packing & Storage	180 kg steel drums or 900 kg IBCs. Hygroscopic: keep tightly closed in a cool, dry place. Like other ethers it can form peroxides on long storage; nitrogen blanketing is recommended once opened. Not regulated as dangerous goods for transport.

FAQ

What is diethylene glycol diethyl ether?	Diethylene Glycol Diethyl Ether (DEGDEE, ethyl diglyme, CAS 112-36-7, C₈H₁₈O₃, MW 162.23) is a colorless, high-boiling glycol diether used as a solvent in inkjet inks, electronic cleaning, coatings and organic synthesis.
Is it the same as diethylene glycol monoethyl ether?	No. Diethylene glycol monoethyl ether (DEGEE, carbitol, CAS 111-90-0) has one free hydroxyl group; DEGDEE (CAS 112-36-7) has both ends capped and no hydroxyl, which makes it aprotic and lower in reactivity. Always check the CAS number.
Why are water and acidity controlled?	In inkjet inks, acidity can corrode printhead parts and moisture affects drying and ink stability; in organometallic reactions, water destroys the reagent. Low water and acidity are therefore the key quality limits.
Is DEGDEE a dangerous good?	No. With a flash point of about 82 °C it is not regulated as dangerous goods for sea, air or road transport. Batch COA and SDS are supplied with each order.
