“…Methacrylic acid (MAA) and methyl methacrylate (MMA) are important monomers for the plastics industry 6. They are mostly used for the production of poly(methyl methacrylate) (PMMA) but also enter the composition of methyl methacrylate‐butadiene‐styrene (MBS) co‐polymers or modified poly(vinyl chloride) (PVC).…”

“…Materials obtained from MAA and MMA are resistant, durable and transparent and can find numerous applications, for instance, as glass substitutes and optical fibres. MAA and MMA are also employed for the preparation of adhesives, paints and coatings 6. 7 Currently, MAA and MMA are produced from fossil resources through different industrial processes, such as the acetone cyanohydrin process or by the oxidation of isobutene or tert ‐butyl alcohol 8.…”

Synthesis of Bio‐Based Methacrylic Acid by Decarboxylation of Itaconic Acid and Citric Acid Catalyzed by Solid Transition‐Metal Catalysts

Methacrylic acid, an important monomer for the plastics industry, was obtained in high selectivity (up to 84%) by the decarboxylation of itaconic acid using heterogeneous catalysts based on Pd, Pt and Ru. The reaction takes place in water at 200-250 °C without any external added pressure, conditions significantly milder than those described previously for the same conversion with better yield and selectivity. A comprehensive study of the reaction parameters has been performed, and the isolation of methacrylic acid was achieved in 50% yield. The decarboxylation procedure is also applicable to citric acid, a more widely available bio-based feedstock, and leads to the production of methacrylic acid in one pot in 41% selectivity. Aconitic acid, the intermediate compound in the pathway from citric acid to itaconic acid was also used successfully as a substrate.

“…Methacrylic acid is still commonly produced by the acetone cyanohydrin process, a process which is not only materialand energy-intensive but also includes the use of hydrogen cyanide, a toxic compound. This process is still economically viable and the one most commonly used (Bauer, 2005). On condition that the conversion of propionic acid to methacrylic acid can be performed with a high yield and in an energy-efficient way, this would provide savings both in the use of toxic chemicals and GHG emissions because production of methacrylic acid makes a significantly higher contribution to global warming than propionic acid (Fig.…”

“…For the six selected routes process modeling was carried out as indicated in Figure 2a and based on information obtained from literature, e.g., Ullmann's encyclopedia,48 technology reviews,49, 50 articles or patents from MMA producers (for route A,51 B,52 C,53 D,54 F,55 and X56) or industrial interviews.…”

Decision framework for chemical process design including different stages of environmental, health, and safety assessment

et al. 2008

in Wiley InterScience (www.interscience.wiley.com).In recent years, many chemical companies have adopted the concept of sustainable development as a core business value. In this context and with focus on early phases, we present a novel design framework that comprises four stages of process modeling and multiobjective evaluation considering monetary and nonmonetary aspects. Each stage is characterized by the available information as a basis for process modeling and assessment. Appropriate modeling approaches, and evaluation indicators for economy, life-cycle environmental impacts, environment, health, and safety (EHS) hazard, and technical aspects are selected for each defined stage. The proposed framework is demonstrated on the design of a methyl methacrylate (MMA) process: considering 17 synthesis routes, the framework is mimicked step-by-step, to select the route with the best multiobjective performances, and to produce an optimized process flowsheet. As a validation of the framework, evaluation profile of six routes over all stages are compared, and crucial points are identified that should be estimated considerably well in early stages of the framework.
