Synthesis of n-butyl acrylate by esterification of acrylic acid with n-butyl alcohol was carried out in a batch membrane reactor. Optimization and design of the experiment was accomplished by response surface methodology with Box-Behnken experimental design. The effects of different parameters like reaction temperature, catalyst concentration, molar ratio of alcohol to acid, and ratio of membrane surface to initial volume on water flux and conversion of acrylic acid were evaluated. A kinetic model for the esterification-coupled pervaporation process was developed. Kinetic parameters were estimated by a nonlinear optimization technique in the MATLAB optimization toolbox. The experimental and simulation results were applied for developing a concept to effectively conduct a pilot-scale esterificationpervaporation experiment.

“…The chemical composition as well as the inoculum for these wastewaters are different. PCW from AA plant usually contains AA in a range of 4-15 wt.% (Ahmad, Kamaruzzaman, & Chin, 2014) where as PRW contains mainly phenolic compounds (Wagner & Nicell, 2001). Hence the total number of electron produced by the decomposition of the substrate might be different.…”

This paper presents the performance of air-cathode microbial fuel cell (AC-MFC) treating the petrochemical wastewater (PCW) from acrylic acid plant. The wastewater which is typically incinerated and possesses very high chemical oxygen demand (COD) due to presence of acrylic acid along with other organic acids. The goal of the present study is to evaluate the viability of treating the wastewater using yeast (Saccharomyces cerevisiae) as biocatalyst in AC-MFC for simultaneous treatment of wastewater and electricity generation. This study demonstrates that Saccharomyces cerevisiae could function as a good biocatalyst producing high power density of 0.24 W/m3 using PCW with an initial COD of 26,000 mg/L. The COD removal efficiency and the columbic efficiency (CE) were found as 38% and 23.6% respectively. The electron transfer process across the electrode/biofilm/solution interface was analyzed by electrochemical impedance spectroscopy (EIS). The present work demonstrates the potential of MFC for the treatment of acrylic acid plant PCW using Saccharomyces cerevisiae as biocatalyst.

In this paper, an acrylic acid-rich wastewater from the production of propylene to acrolein was used to synthesize the polycarboxylate superplasticizers. First, the acrylic acid-rich wastewater was oxidized. Then, two kinds of unsaturated polyether macromonomers {methallyl polyethylene glycol (HPEG) and isoprenol polyethylene glycol (IPEG)} and the oxidized wastewater were copolymerized with it, respectively, by free radical polymerization in aqueous solution. The monomer conversion, molecular weight, molecular weight distribution of the copolymers of gel permeation chromatography (GPC) were characterized. The performance of the two copolymers was characterized by measuring paste flow, adsorption using GPC method, and the applied behavior of premixed concrete. The results showed that the synthesized copolymers could meet the requirement of application in contrast to the commodity product.
