[More] A prospective study on the product distribution at chemical equilibrium for the simultaneous liquid-phase etherification of isobutene and isoamylenes with ethanol over Amberlyst (TM) 35 is presented. Experiments were performed isothermally in a 200 cm(3) stirred tank batch reactor operating at 2.0 MPa. Initial molar ratios of alcohol/olefins and isobutene/isoamylenes ranged both from 05 to 2, and temperature from 323 to 353 K. Reactants equilibrium conversion, selectivities and yields toward products were clearly affected by the experimental conditions. Experimental etherification yields have been modeled using the response surface methodology (RSM), combined with the stepwise regression method to include only the statistically significant variables into the model. The multiobjective optimization (MOO) of etherification yields has been carried out numerically, by means of the desirability function approach, and graphically, by using the overlaid contour plots (OCP). Optimal conditions for the simultaneous production of ethyl tert-butyl ether (ETBE) and tert-amyl ethyl ether (TAEE) have been found to be at low temperatures (323 to 337 K) and initial molar ratio alcohol/olefins close to 0.9 and isobutene/isoamylenes close to 0.5.

[More] Sustainable process design for TAEE synthesis process is performed by comparing three case studies (CS1, CS2 and CS3) based on two PFDs with different separation section (classical water-ethanol extraction method and pressure swing distillation) and different recycle streams. Heat integration (HI) of distillation columns is considered for two of the case studies. Feedstock for TAEE production process is represented by Light Cycle Naphtha enriched in 2-methyl-1-butene and 2-methyl-2-butene. Results point out that best performance is achieved for CS2 (pressure swing distillation and EtOH recycle): no danger to contaminate gasoline with water, EtOH recovery, and better energy performance.

[More] The paper proposes a novel process integration for biodiesel blend in the Membrane assisted Reactive Divided Wall Distillation (MRDW) column. Biodiesel is a green fuel and grade of biodiesel blend is B20 (%) which consist of 20% biodiesel and rest 80% commercial diesel. Instead of commercial diesel, Tertiary Amyl Ethyl Ether (TAEE) was used as an environment friendly fuel for blending biodiesel. Biodiesel and TAEE were synthesized in a pilot scale reactive distillation column. Dual reactive distillation and MRDW were simulated using aspen plus. B20 (%) limit calculation was performed using feed flow rates of both TAEE and biodiesel. MRDW was compared with dual reactive distillation column and it was observed that MRDW is comparatively cost effective and suitable in terms of improved heat integration and flow pattern.

[More] TAEE conferences, which was begun in 1996 edition, has provided a great amount of technical and educational papers. After 11 editions and 22 years of existence, it can be said that, TAEE conferences and the Association responsible of their organization is more than a meeting about Electronics Education among teachers, professors, technicians, engineers and researchers every 2 years.

It is a living community sharing and providing much of what is taught in Spain and transmitted in the field of Electronics. Throughout all this time, TAEE conferences have become a reference for many people. Following the work "Semiautomatic Creation of educational objects and TAEE meta-analysis", carried out in 2008, documentation generated in TAEE has been homogenized, resulting in the current unified structure of objects contained in all TAEE papers, available and free access through the digital platform eSpacio-UNED.

[More] Obesity is a common disease worldwide that often results in serious conditions including hypertension, diabetes, and hyperlipidemia. Many herbal medicines have been examined with regard to ameliorating obesity. We investigated the anti-obesity effects of 50% EtOH extract of Triticum aestivum sprout (TAEE) in high-fat-diet (HFD)-induced obese mice. TAEE administration (10, 50, or 200 mg/kg) for 6 weeks significantly decreased the body weights, serum total cholesterol (TC), and low-density lipoprotein cholesterol levels in HFD-fed mice. TAEE treatment reduced lipid accumulation in epididymal white adipose tissue (EWAT) and liver. Moreover, TC and lipid levels were decreased by TAEE treatment in liver. Serum leptin and adiponectin concentrations were reduced by TAEE treatment. TAEE-treated mice showed decreases in peroxisome proliferator-activated receptor γ (PPARγ) and fatty acid synthase expression in EWAT. Furthermore, TAEE administration elevated levels of PPARα protein in the liver of HFD-induced obese mice. These results suggest that TAEE supplementation might be beneficial for the treatment and prevention of obesity and related diseases.

Here, we report the draft genome sequence of M. sp. strain T29 together with the description of the genome properties and its annotation. The draft genome consists of 608 contigs with a total size of 4,449,424 bp and an average coverage of 150x. The genome exhibits an average G + C content of 68.7 %, and contains 4754 protein coding and 52 RNA genes, including 48 tRNA genes. 71 % of the protein coding genes could be assigned to COG (Clusters of Orthologous Groups) categories. A formerly unknown circular plasmid designated as pT29A was isolated and sequenced separately and found to be 86,856 bp long.

[More] This paper examines the oxidation reaction of tert-amyl methyl ether (TAME), an oxygenated fuel additive, with chlorine radical initiators in the presence of oxygen. Data are collected at 298, 550, and 700 K. Reaction intermediates and products are probed by a multiplexed chemical kinetics synchrotron photoionization mass spectrometer (SPIMS) and characterized on the basis of the mass-to-charge ratio, ionization energy, and photoionization spectra. Branching fractions of primary products are obtained at the different reaction temperatures. CBS-QB3 computations are also carried out to study the potential energy surface of the investigated reactions to validate detected primary products.

Effect of water addition on the simultaneous liquid-phase etherification of isobutene and isoamylenes with ethanol over amberlyst (TM) 35

Authors: Soto, R; Fite, C; Ramirez, E; Tejero, J; Cunill, F (2015) HERO ID: 4641884

[More] The simultaneous liquid-phase etherification of isobutene and isoamylenes with ethanol has been carried out at 353 K over Amberlyst (TM) 35. The initial molar ratios of alcohol/olefins and isobutene/isoamylenes were both maintained constant at 0.5 and 1, respectively. The effect of water presence on the reaction system has been studied by the addition of water to the initial reactant mixture, ranging from 0 to 1 wt.%. Under experimental conditions, product distribution, as well as etherification reaction rates, have been clearly affected by the addition of water. Water favors the formation of tertiary alcohols through olefins hydration because of its preferential adsorption on the active sites, while it hinders etherification and dimerization reactions. The inhibitory effect of water was more noticeable on dimerization than on etherification. Based on specific theories about the dissociation of the active sites from the catalytic network, the amount of water required to dissociate all the sulfonic groups has been estimated. Finally, the feasibility of the bioethanol use as a reactant has also been evaluated. (C) 2015 Elsevier B.V. All rights reserved.
