TRI ETHYLENE GLYCOL
RXSOL-19-1464-210Application & Usage
- Triethylene glycol is a solvent prepared from ethylene oxide and ethylene glycol.
- Triethylene glycol can be used:
- To prepare fatty acid gelators, which are used to gelate various edible and vegetable oils.
- As a solvent to prepare superparamagnetic iron oxide nanoparticles for in situ protein purification.
- As an absorbent agent in the subsea natural gas dehydration process.
- Triethylene glycol is used as a plasticizer, as an additive for hydraulic fluids and brake fluids, and as a disinfectant. It is an active component of certain pigments, printing dyes, inks and paste.
- It finds application as a liquid desiccant and used in the dehydration of natural gas, carbon dioxide, hydrogen sulfide and air conditioning systems.
- It plays as an important role in anti-freeze and de-icing products, cleaning and furnishing care products, lubricant and greases.
Procedure
Octane-1,8-diol in which the carbon atoms at positions 3 and 6 have been replaced by oxygen atoms
