Etheramines and their quaternaries are well known surfactants. AkzoNobel has developed experimental technology for preparing a class of novel amine compounds containing ether linkages. These new materials have structures such as the ones shown below.

The etherdiamines are generally low-melting solids at room temperature, but 1, R = HT and R′ = 2-ethyl¬hexyl is a liquid. The oligomers are viscous, solvent-free liquids. Viscosity for 2, R = C12 for example is from 200 to 450 cP at 30°.

In addition, we have synthesized quaternaries such as the following:

These gemini quaternaries were made at 85-90% concentration in alcohols and are solids at room temperature. Diquaternary 3, R = HT and R′ = 2-ethyl¬hexyl is a hexane-soluble liquid!

These experimental products are available in laboratory quantities, and related compounds can be prepared to your design.

The potential uses for this class of etheramines and their quaternaries are still largely unexplored. Similar compounds have been used as polyurethane catalysts, as transfection agents, in wood preservation and in emulsification. Other derivatives could be prepared from these developmental etheramines. Use your creativity to imagine the possibilities, and get in touch with AkzoNobel, where our technical expertise can provide you “Tomorrow’s Answers Today!”
