Ethoxylation and Propoxylation

The ethoxylation reaction - adding ethylene oxide (EO) to the compounds containing dissociated protons
can generate a variety of ethoxylates for many applications. The formed ethoxylates have the following
general structure:



Where, R can be but not limited to the following compounds:
Fatty Alcohol
Fatty Acid
Fatty Amine
Alcohol
Alkyl Phenol.
The properties of the ethoxylates may be tuned significantly by changing n - the addition number of
ethylene oxide.  Furthermore, if the compound, R, has multiple end groups of hydroxyl, carboxyl, or amine,
the final ethoxylate can appear as a multiple PEG arm structure.

We are well prepared to perform ethoxylation services with your designated initial compounds. On the
other hand, propoxylation - a similar reaction process of using propylene oxide (PO) can also be done in
our lab, which will make different propoxylates, even copolymers of PO/EO when PO and EO are used
simultaneously.
