1. A method of making 3-alkoxytetraalkylene sulfone comprising:
- mixing an alcohol and a catalyst to form a first mixture;
reacting alkadiene sulfone with the first mixture to form a reaction product;
contacting the reaction product with water and heating the reaction product and water to a temperature sufficient to provide an organic phase and an inorganic phase; and
separating the organic phase and inorganic phase from one another,wherein the organic phase contains less than about 2000 ppm water.

Abstract
A method of making 3-alkoxytetraalkylene sulfone. The method includes mixing an alcohol and a catalyst to form a first mixture. Alkadiene sulfone is reacted with the first mixture to form a reaction product. The reaction product is contacted with water at conditions sufficient to provide an organic phase and an inorganic phase. Subsequent to contacting the reaction product with water, the organic phase and inorganic phase are separated from one another.
