To gain further insights into the key *C3 intermediates for propylene production, we performed the electrochemical reduction of allyl alcohol, propionaldehyde, hydroxyacetone and propylene glycol by dissolving them in KOH + CsI electrolyte. The possibility of decomposition of these compounds in alkali...
“Additionally, Chandra Asri Group will help fill gaps in the supply of chemical products, such as monoethylene glycol (MEG), polyols, and ethylene, propylene, and styrene monomers, to support manufacturing processes in the country,” it said. “This will ensure that the country’s energy ...

Transmission electron microscopy (TEM) photograph and X-ray photoelectron spectroscopy (XPS) analysis of nanoporous graphene nanosheets indicated that the structure of nano- pore was irregular and the oxygen-containing groups in the surface were limited. More importantly, the as-prepared MMMs presented ...
