Chementator: A direct route to TPAL promises to be less expensive and greener

LG Chem, Ltd. (Seoul, South Korea; edlinks.chemengonline.com/5826-545) has developed a direct oxidation process for making terephthalaldehyde (TPAL; terephthalic aldehyde), a key intermediate for dyestuffs, pharmaceuticals, specialty polymers, and other fine chemicals. Because the conversion requires only one reaction step and…

Chementator: Converting trees into biodegredation plants

Large tracts of land that have been used for military training, especially in the U.S., are contaminated with RDX— a widely used explosive that is both toxic and carcinogenic. Although bacteria have been isolated that can biodegrade the RDX, the…

Chementator: Improved catalysts are now ready for hydrotreating petroleum fuel

Haldor Topsøe (Lyngby, Denmark; edlinks.chemengonline.com/5826-533) has introduced two new hydroprocessing catalysts, which are based on its proprietary BRIM technology. Both catalysts are nickel-molybdenum types that optimize both hydrogenation at so-called brim sites (situated on the basal-plane of the catalyst) and…

Chementator: Nanotubes

Scientists at the Lawrence Livermore National Laboratory (Calif.; edlinks.chemengonline.com/5826-549), Boston College (edlinks.chemengonline.com/5826-550) and MIT (both Mass.; edlinks.chemengonline.com/5826-551) have discovered that by heating a single-walled nanotube of carbon to 3,600°F, its strength is increased by 280%. The discovery is expected to…

Chementator: A new anode may double the energy density of Li-ion batteries

Using lithium metal as the anode of secondary Li-ion batteries would double the energy density of conventional batteries, which use anodes based on carbon. However, Li-based anodes suffer from the problem of dendrite crystal formation during the charge and discharge…
