Rubidium acetate (CH₃COORb) is the rubidium salt of acetic acid. It is a white, hygroscopic solid.^[1] It can be prepared by reacting rubidium metal, rubidium carbonate, or rubidium hydroxide^[3] with acetic acid.

Uses

Rubidium acetate is used as a catalyst for the polymerization of silanol terminated siloxane oligomers.^[4]
