Chemical Properties
colourless to faintly yellow liquid
Uses
Triethylene glycol monobutyl ether (TEGMBE) can be used as a solvent:
- In the synthesis of superparamagnetic iron oxide nanoparticles by thermal decomposition method.
- in the removal of CO2 due to its solubilize CO2.
It can also be used as a reactant in the preparation of polyether adducts of bis(1,1,1,5,5,5-hexafluoro-2,4-pentanedionato)barium.
Uses
Triethylene glycol monobutyl ether, glycol ether a highly effective carrier solvent for textile dye processes. With superior surface tension characteristics, water solubility and solvency for oils, it has potential for use in household, institutional, industrial and special-purpose cleaners. The coupling ability of this product enhances performance and improves shelf stability of cleaning products. It is also used as an active solvent for solvent-based coatings, dye carrier for textile dye processes, coupling agent and solvent in household and industrial cleaners, paint and floor polish strippers, hard surface cleaners, and disinfectants, chemical process solvent and intermediate for ester production used as solvents, surfactants and plasticizers, coupling agent for resins and dyes in water-based printing ink, component of high-boiling hydraulic brake fluids.
Uses
Plasticizer, intermediate.
Flammability and Explosibility
Non flammable
Synthesis
The synthesis of triethylene glycol monobutyl ether can be achieved by etherification of ethylene glycol with butanol. Usually the etherification reaction is carried out under acidic or alkaline conditions, and appropriate amount of catalyst is added to promote the reaction. The temperature and reaction time are controlled and the reaction mixture is purified by distillation to obtain pure triethylene glycol monobutyl ether.
Toxics Screening Level
The initial threshold screening level (ITSL) for triethylene glycol monobutyl ether (synonym: butoxytriethylene glycol) is 18 μg/m3 (annual averaging time).
