Oberflächensulfonierte Ionentauscher vermeiden Nebenreaktionen bei der heterogen katalysierten Veresterung

Study of the esterification reaction of acetic acid with n -butanol over supported WO 3 catalysts

“…Concerning the esterification reaction of acetic acid with nbutanol, this is the most viable route for producing butyl acetate which is an important chemical being used in large quantities as a solvent in the lacquer industry and coating manufacture, extractant and dehydrator [16][17][18]. It is also able to replace the toxic and teratogenic ethoxy ethyl acetate, often used as a solvent [19].…”

The Functionality of Ion Exchange Resins for Esterification, Transesterification and Hydrogenation Reactions

“…N-butanol reaction with acetic acid yielding n-butyl acetate at temperature ranged 100-120°C in a reactor (fixed bed) was studied to determine the resin influence on various side reactions. [63] Ion-exchange resin of three (3) types, dissimilar in sulfonated content; Amberlyst TM 48 (bi-sulfonated), Purolite TM CT 269 (mono-sulfonated), and Amberlyst TM 46 (surface-sulfonated) showed similar activity in esterification reaction. With regards to the side reaction, Amberlyst TM 48 and Purolite TM CT 269 gave similar results with side reactions.…”

Biodiesel production via esterification of oleic acid catalyzed by MnO2@Mn(btc) as a novel and heterogeneous catalyst

“…Instead of using an alkali catalyst, an acid catalyst can be employed to convert the FFAs into biodiesel through the esterification reaction . In recent years, many surveys on catalysts for the esterification or transesterification step have indicated the use of sulfated alumina, carbon‐based solid acid, supported heteropolyacids, cation‐exchange resins with strong acidity, waste silicone solid base, fe3o4@gly, LiFe 5 O 8 ‐LiFeO 2 , Li 2 TiO 3 , or Li 4 SiO 4 …”
