Investigation of kinetics of the reaction indicated that the increasing the [Ac/EtOH] molar ratio is favoured for esterification reaction, this is due to the reaction is catalyzed by acid. The maximum conversion, approximately 83% was obtained at 65掳C for molar ratio of Ac/5EtOH. With the ...
The esterification reaction between acetic acid and ethanol was studied in a continuous flow pervaporation membrane reactor utilizing a polymeric/ceramic c... Y Zhu,RG Minet,TT Tsotsis - 《Chemical Engineering Science》 被引量: 185发表: 1996年 Esterification of acetic acid with isopropanol coupled ...
Esterification of acetic acid with butanol in the presence of ion-exchange resins as catalysts The esterification of acetic acid with n-butanol was studied in the presence of ion-exchange resin catalysts such as Amberlyst-15 to determine the intrinsic reaction kinetics. The effect of various ...
Acetic acid bacteria (AAB) play a pivotal role in the food fermentation industry, especially in vinegar production, due to their ability to partially oxidize alcohols to acetic acid. However, economic bioproduction using AAB is challenged by harsh enviro

The conversion of ethanol to acetic acid via the oxidative route is strongly exothermic. Due to the strong exothermic nature the reaction must be performed in a reactor type provided with efficient heat removal means, i.e. high areas of heat transfer are mandatory, which results in an expensive...
Eleven patients with a history of anaphylaxis, positive reactions to skin tests, and specific IgE antibody to wasp venom underwent hyposensitisation in a six hour procedure. No general reactions occurred. Complement activation and protei...
