Triethylene glycol synthesis

10synthesis methods
Triethylene glycol, like diethylene glycol, is produced commercially as a by-product of ethylene glycol production. Its formation is favored by a high ethylene oxide to water ratio.

Yield:-

Reaction Conditions:

with titanium(IV) oxide in tetrahydrofuran at 120; under 2250.23 Torr;Inert atmosphere;

Steps:

2.3. Reaction procedure for alkoxylations with solid catalyst

General procedure: The corresponding nucleophile (water or alcohol, typically 0.5mmol), 1.8 ml of ethylene oxide in THF (6 mmol, 3.3 M) and 65 mg of solid catalyst (25 wt%) were placed in a double-walled 6 mL vial, equipped with a magnetic stirrer. The reactor was closed with a screw cap connected to a manometer. The reactor was purged three times withN2 and finally charged with 3 bars of N2. The reaction mixture wasplaced in a pre-heated oil bath at 120 °C and magnetically stirred over 16 h. At the end of the reaction, the mixture was cooled, filtered,concentrated and analyzed by 1H-NMR and GC-MS.
