Abstract
A new method for fabricating glycol monoalkyl ether acetate (GMAEA) is provided. A Bronsted acidic ionic liquid is used. After some reactions, two layers of materials are formed. A product of GMAEA is obtained at the upper layer. The lower layer is the ionic liquid. Thus, the ionic liquid is reusable for re-fabricating the product. And, furthermore, waste acid is reduced.
