“…This large deviation might be caused by some polymerization of AAc in the column despite the fact that in the experiments performed using AAc, the concentration of this species was never higher than 50 mol %, because of the risk of polymerization and also to avoid possible corrosion of the experimental set up components such as the peristaltic pumps. Nevertheless, it is known that AAc tends to polymerize at high temperatures . Indeed, after the adsorption experiments performed with this binary mixture, the column was opened and it was observed the presence of an apparently viscous polymer like a colorless gel with elastic properties in the bulk.…”

“…Furthermore, during this esterification reaction, there is a high risk of polymerization, mainly at high temperatures . According to several research works, the addition of an inhibitor helps to avoid the polymerization step; phenothiazine (Ptz) and hydroquinone monomethyl ether have been the most commonly used inhibitors; however, in a recent study, the researchers concluded that Ptz is the most effective one.…”

Synthesis of butyl acrylate in a fixed‐bed adsorptive reactor over Amberlyst 15

et al. 2014

The butyl acrylate synthesis from the esterification reaction of acrylic acid with 1‐butanol in a fixed‐bed adsorptive reactor packed with Amberlyst 15 ion exchange resin was evaluated. Adsorption experiments were carried out with nonreactive pairs at two temperatures (323 and 363 K). The experimental results were used to obtain multicomponent adsorption equilibrium isotherms of Langmuir type. Reactive adsorption experiments using different feed molar ratios and flow rates were performed, at 363 K, and used to validate a mathematical model developed to describe the dynamic behavior of the fixed‐bed adsorptive reactor for the butyl acrylate synthesis. Due to the simultaneous reaction and separation steps, it was possible to obtain a butyl acrylate maximum concentration 38% higher than the equilibrium concentration (for an equimolar reactants ratio solution as feed at a flow rate of 0.9 mL min−1 and 363 K) showing that sorption‐enhanced reaction technologies are very promising for butyl acrylate synthesis. © 2014 American Institute of Chemical Engineers AIChE J, 61: 1263–1274, 2015

“…The exposure of PEA polymer to nitric acid aqueous solutions seemed to change a number of ethyl acrylate monomer units into ethyl acrylate ones, by replacement of a hydrogen for the ethyl group, thus reverting the esterification process by which ethyl acrylate monomer results from acrylic acid [27].…”

Hydrophilic surface modification of acrylate-based biomaterials

et al. 2016

Acrylic polymers have proved to be excellent with regard to cell adhesion, colonization and survival, in vitro and in vivo. Highly ordered and regular pore structures thereof can be produced with the help of polyamide templates, which are removed with nitric acid. This treatment converts a fraction of the ethyl acrylate side groups into acrylic acid, turning poly(ethyl acrylate) scaffolds into a more hydrophilic and pH-sensitive substrate, while its good biological performance remains intact. To quantify the extent of such a modification, and be able to characterize the degree of hydrophilicity of poly(ethyl acrylate), poly(ethyl acrylate) was treated with acid for different times (four, nine and 17 days), and compared with poly(acrylic acid) and a 90/10%wt. EA/AAc copolymer (P(EA-co-AAc)). The biological performance was also assessed for samples immersed in acid up to four days and the copolymer, and it was found that the incorporation of acidic units on the material surface was not prejudicial for cells. This surface modification of 3D porous hydrophobic scaffolds makes easier the wetting with culture medium and aqueous solutions in general, and thus represents an advantage in the manageability of the scaffolds.

“…Das Verfahren wurde von der Firma DuPont in Kooperation mit dem Biotechnologieunternehmen Genencor entwickelt, um zumindest eine Komponente des Polyesters Polypropylenterephthalat (Sorona) als regenerativ gewonnen ausweisen zu können. [23]. Jüngst wurde über die Hydrodesoxygenierung mit einem Ir-ReO x /SiO 2 -Katalysator berichtet, an dem 1,3-Propandiol mit einer Selektivität von 60 % (mit Propanol als Nebenprodukt) gebildet wird [19].…”

“…Alternativen auf fossiler Basis gehen von Acetylen aus und wurden früher in industriellem Maßstab genutzt [23]. Im Falle des von der BASF in der Vergangenheit eingesetzten Verfahrens wird Acetylen mit CO und Wasser in Gegenwart von Ni/Cu-Bromid als Katalysator bei 140 bar und 200°C umgesetzt.…”

Herstellung von Grundchemikalien auf Basis nachwachsender Rohstoffe als Alternative zur Petrochemie?

Die derzeitige Entwicklung in den USA, geprägt durch billiges Schiefergas, hat starke Auswirkungen auf die Produktion von Basischemikalien. Der Beitrag geht der Frage nach, ob sich vor diesem Hintergrund der Anteil nachwachsender Rohstoffe für die Chemikalienproduktion steigern lässt oder ob sich die Zahl biobasierter Produkte und Verfahren eher verringern wird. Antworten liefert für einige ausgewählte Grundchemikalien der Vergleich von bestehenden Produktionsverfahren auf petrochemischer Basis mit Alternativen auf Basis nachwachsender oder anderer fossiler Rohstoffe (bspw. Methan und niedere Alkane).
