# Potassium ethoxide

Is it possible to make potassium ethoxide by mixing $$\ce{KOH}$$ and $$\ce{EtOH}$$ in the presence of a dehydrating agent like $$\ce{MgSO4}$$ or $$\ce{CaO}$$ or $$\ce{K2CO3}$$?

The easy way is adding metallic potassium to ethanol. But nobody likes to deal with potassium or hydrogen.

My understanding is that added $$\ce{KOH}$$ reacts with $$\ce{EtOH}$$ in a reversible way. But if there is a water absorber the product water is gone so the reaction moves to the right side.

$$\ce{C2H5OH + KOH <=> C2H5OK + H2O}$$

• Better way is buy it: Sigma-Aldrich sells it in 95% pure form for USD 39.90/100 g. – Mathew Mahindaratne Apr 7 '19 at 18:04
