Activities of Heterogeneous Acid-Base Catalystsfor Fragrances Synthesis: A Review
Daftar Isi:
- This paper reviews various types of heterogeneous acid-base catalysts for fragrancespreparation.Catalytic activities of the various types of heterogeneous acid and base catalysts in fragrances preparation, i.e.non-zeolitic, zeolitic, and mesoporous molecular sieves, have been reported. Generally, heterogeneous acid cata-lysts are more commonly used in fragrance synthesis as compared to heterogeneous base catalysts. Heteropoly acids and hydrotalcites type catalysts are widely used as heterogeneous acid and base catalysts, respectively.
