Abstract

The kinetic behavior of the heterogeneous hydrolysis of aqueous ethyl acetate over an acidic cation exchange resin, Amberlyst 15, was investigated. The experiments were carried out in a fixed bed reactor at temperatures from 313.15 to 343.15 K and feed molar ratios ,θBo (water to ethyl acetate) from 62.4 to 265.88. The conversion of ethyl acetate was found to increase with increasing reaction temperature. Gas bubble formation was observed at reaction temperature ≥ 343.15K. Absence of mass transfer resistance was verified by conducting the experiments at different catalyst loadings (20 g, 40 g, 64 g) under varied feed flow rates (1 to 25 cm3/min ). The kinetic data was correlated with pseudo first order model and model parameters were determined using Nelder-Mead algorithm for minimizing the objective function. © 2009 by Authors, Published by BCREC Group.

Journal Author(s) Rights

In order for Masyarakat Katalis Indonesia - Indonesian Catalyst Society (MKICS) and BCREC Publishing Group to publish and disseminate research articles, we need non-exclusive publishing rights (transfered from author(s) to publisher). This is determined by a publishing agreement between the Author(s) and Masyarakat Katalis Indonesia - Indonesian Catalyst Society (MKICS) and BCREC Publishing Group. This agreement deals with the transfer or license of the right for publishing to Masyarakat Katalis Indonesia - Indonesian Catalyst Society (MKICS) and BCREC Publishing Group, while Authors still retain significant all copy rights to use and share their own published articles. Masyarakat Katalis Indonesia - Indonesian Catalyst Society (MKICS) and BCREC Publishing Group supports the need for authors to share, disseminate and maximize the impact of their research and these rights, in any databases.

As a journal Author, you have all copy rights for a large range of uses of your article, including use by your employing institute or company. These Author copy rights can be exercised without the need to obtain specific permission. Authors who publishing in BCREC journals have wide copy rights to use their works for teaching and scholarly purposes without needing to seek permission, including, but not limited to:

use for classroom teaching by Author or Author's institution and presentation at a meeting or conference and distributing copies to attendees;
use for internal training by author's company;
distribution to colleagues for their reseearch use;
use in a subsequent compilation of the author's works;
inclusion in a thesis or dissertation;
reuse of portions or extracts from the article in other works (with full acknowledgement of final article);
preparation of derivative works (other than commercial purposes) (with full acknowledgement of final article);
voluntary posting on open web sites operated by author or author’s institution for scholarly purposes,

(but it should follow the open access license of Creative Common CC-by-SA License).

Authors/Readers/Third Parties can copy and redistribute the material in any medium or format, as well as remix, transform, and build upon the material for any purpose, even commercially, but they must give appropriate credit (the name of the creator and attribution parties (authors detail information), a copyright notice, an open access license notice, a disclaimer notice, and a link to the material), provide a link to the license, and indicate if changes were made (Publisher indicates the modification of the material (if any) and retain an indication of previous modifications using a CrossMark Policy and information about Erratum-Corrigendum notification).
