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 ...
Introduction Conclusions References
The current work is aimed at the experimental investigation of the aldehyde and BTX (benzene, toluene and Xylene) pollutants emitted from a light duty spark ignition (SI) vehicle fueled on gasoline and ethanol-gasoline blended fuel, operating with a three-way catalytic converter (TWC). At the same time, the specific reactivity (SR) of these pollutants has also been addressed in this paper. The ...
