Vapor-phase carbonylation of dimethoxymethane over H-Faujasite.
Carbonylation gets a phase lift: The usual liquid-phase, high-pressure processes for carbonylating formaldehydes are avoided in a novel vapor-phase reaction. Using an acid zeolite (Faujasite) at near-atmospheric pressure dimethoxymethane (DMM; the dimethyl acetal of formaldehyde; see scheme) is carbonylated to produce methyl methoxyacetate (MMAc). This approach provides a new route to ethylene ...
متن کاملTheoretical Study of Zeolite-Catalyzed Dimethoxymethane Carbonylation to Methyl Methoxyacetate
The gas-phase carbonylation of dimethoxymethane (DMM) to form methyl methoxyacetate (MMAc) can be catalyzed by acid zeolites. This reaction is a critical step in the synthesis of monoethylene glycol (MEG), a widely used chemical, from synthesis gas. The mechanism of DMM carbonylation occurring on H-MFI and H-FAU zeolites has been investigated using density functional theory. We find that the re...
متن کاملVapor-phase synthesis of nanoparticles
An overview of methods for preparing nanoparticles in the vapor phase is given, and recent advances are reviewed. Developments in instrumentation for monitoring vapor-phase synthesis of nanoparticles and in modeling these processes are also included. The most important developments relate to improved control and understanding of nanoparticle aggregation and coalescence during synthesis, and to ...
متن کاملVapor phase tri-methyl-indium seeding system suitable for high temperature spectroscopy and thermometry.
Tri-methyl-indium (TMI) is used as an indium transport molecule to introduce indium atoms to reactive hot gas flows/combustion environments for spectroscopic diagnostics. A seeding system was constructed to allow the addition of an inert TMI laden carrier gas into an air/fuel mixture burning consequently on a burner. The amount of the seeded TMI in the carrier gas can be readily varied by contr...
متن کاملSynthesis of Polypyrrole Coated SnO2-ZnO Electrospun Nanofibers via Vapor Phase Polymerization Method
This paper reports the synthesis of polypyrrole coated SnO2/ZnOelectrospunnanofibers via vapor phase polymerization method. In order to prepare one dimensional (SnO2- ZnO)/polypyrrole with the core sheath structure, first SnO2-ZnO composite nanofibers were synthesized via electrospinning method followed by adsorption of Fe 3+ on the surface of the SnO2-ZnO nanofibers and finally pyrrole w...
