Applications

Pentaethylene glycol is used as an intermediate in the synthesis of cyclic and noncyclic polyethers, complexing agents and immobilized phase-transfer catalysts. It acts as a catalyst for potassium hydroxide induced elimination reactions in benzene. Further, it is used in functional fluids and viscosity adjustors.

Notes

Hygroscopic. Incompatible with strong oxidizing agents, acid chlorides and acid anhydrides.
