An optimisation-based framework for the conceptual design of reaction-separation processes

Prior to detailed process design, it is vital to first generate a good flowsheet that meets particular objective. This is particularly the case in bio-based materials and products, where, given a range of chemistries, the synthesis problem is not about the best way to make a particular product but rather the best way to convert a specific feedstock. In order to do so, an optimisation-based framework, which can be used to identify the optimal configuration of a process network that consists of both reactions and separation systems to achieve maximum economic potential, is presented in this paper. A process superstructure, which includes the concept of master reaction stages and subsidiary separation stages, is introduced to facilitate the theory. The problem is formulated as a generalised mixed integer linear programming (MILP) model which accounts for the simultaneous selection of products and identification of the process configuration. The solution of the optimisation problem includes the best possible economic performance, identification of active reactions, reaction ordering and separation sequences along with the corresponding flowsheet of the optimal process. The economic criterion takes account of raw materials costs, product values and separation related costs. Two bio-based chemical case studies are presented to illustrate the applicability of the proposed methodology.

The proportionality constant is the rate constant for the particular unimolecular reaction. the reaction rate is directly proportional to the concentration of the reactant. I hope my blog about 4100-80-5 is helpful to your research. Application of 4100-80-5

METHOD FOR PRODUCING COMPOSITIONS OF FURAN GLYCIDYL ETHERS, COMPOSITIONS PRODUCED AND USES OF SAME

A method for producing a composition of glycidyl ethers synthesised from furan derivatives (furan glycidyl ethers), partly characterized by azeotropic distillation performed under reduced pressure and without the addition of a catalyst. Such products are used to produce epoxy resins, with the aim of forming a three-dimensional macromolecular network. With the compositions of the invention the cross-linking density of the network is increased, allowing the production of a material which is more resistant, both chemically and mechanically, and has a higher glass transition temperature (Tg) than the same materials produced with compositions of furan glycidyl ethers synthesized at atmospheric pressure according to prior art.

Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions.Quality Control of (cis-Tetrahydrofuran-2,5-diyl)dimethanol, you can also check out more blogs about2144-40-3

Quantification of furandiones in ambient aerosol

Furandiones are products of the photooxidation of anthropogenic volatile organic compounds (VOC), like toluene, and contribute to secondary organic aerosol (SOA). Because few molecular tracers of anthropogenic SOA are used to assess this source in ambient aerosol, developing a quantification method for furandiones holds a great importance. In this study, we developed a direct and highly sensitive gas chromatography-mass spectrometry method for the quantitative analysis of furandiones in fine particulate matter that is mainly free from interference by structurally-related dicarboxylic acids. Our application of this method in Iowa City, IA provides the first ambient measurements of four furandiones: 2,5-furandione, 3-methyl-2,5-furandione, dihydro-2,5-furandione, and dihydro-3-methyl-2,5-furandione. Furandiones were detected in all collected samples with a daily average concentration of 9.1?¡À?3.8?ng?m?3. The developed method allows for the accurate measurement of the furandiones concentrations in ambient aerosol, which will support future evaluation of these compounds as tracers for anthropogenic SOA and assessment of their potential health impacts.

Sometimes chemists are able to propose two or more mechanisms that are consistent with the available data.

The invention relates to imidazopyridinones, to their use in medicine, to compositions containing them, to processes for their preparation and to intermediates used in such processes. By activating TLRs, it should be possible to induce or stimulate immune cells to mount an immune response. In particular, the TLR7 has been implicated in viral infections (such as HCV or HBV), cancers and tumours, and T2 Helper cell (TH2) mediated diseases, and hence TLR7 agonists are potentially useful in the treatment of such diseases. We have now found a series of imidazopyridinones which are agonists of TLR7.
