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…
Last month, Agilent Technologies, Inc. (Palo Alto, Calif.; edlinks.chemengonline.com/5826-546) launched the 1200 Series liquid chromatography (LC) system, replacing its predecessor, the 1100 Series LC. With more than 60 instrument modules available, the 1200 Series can be configured for all major…
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…
A gas-liquid nozzle that reduces the size of the gas bubbles blown into a liquid — thus increasing the rate at which the gas is absorbed into the liquid — has been developed by a research team led by Jie…
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…
Lanxess Deutschland GmbH (Leverkusen, Germany; edlinks.chemengonline.com/5826-548) has commissioned a parallel reactor for the screening of catalysts use in hazardous reactions, such as phosgenation and chlorination, which are commonly used to make fine chemicals. Up to now, existing automated screening devices…
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…
The Technical University of Denmark (Lyngby; edlinks.chemengonline.com/5826-552) has received a grant from the A. P. Møller and Chastine McKinney Møller Foundation to develop the world’s most powerful miocroscope. The so-called environmental transmission electron miocroscope is said to be five time…
Total Petrochemicals (Brussels; edlinks.chemengonline.com/5825-531) and UOP LLC (Des Plaines, Ill.; edlinks.chemengonline.com/5825-532) plan to construct at Total Petrochemicals site in Feluy, Belgium, a demonstration plant consisting of a UOP/Hydro methanol-to-olefin (MTO) process integrated with a Total Petrochemicals/UOP Olefin Cracking process (OCP)…
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…
