Acetins Production via Transesterification of Ethyl Acetate with Glycerol Using Heterogeneous Acid Catalysts.

Acetins Production via Transesterification of Ethyl Acetate with Glycerol Using Heterogeneous Acid Catalysts.

Meireles, Bruno Amaral; Pereira, Vera Lúcia Patrocinio

Abstract:

Acetins are raw-material widely utilized in chemical, pharmaceutical and cosmetic industries. Traditionally, acetins are produced by glycerol esterification with excess of acetic acid and/or acetic anhydride but this process has drawbacks as high cost and use of corrosive and toxic reagents. We wish to report a new and efficient route to produce acetins via an acid catalyzed transesterification reaction of glycerol with ethyl acetate in heterogeneous media (Figure 1) using dry amberlyst A-15 (A) and wet amberlyst A-16 (B) as catalysts.
