Metals-‘free’ H3PO4 is now available off the shelf
A new phosphoric acid that contains less than 100 parts per billion of 30 different metal ions is now commercially available from Febex S.A. (Box, Switzerland; edlinks.chemengonline.com/5828-539), the phosphorous specialties subsidiary of CECA Arkema Group (Paris). The new grade of…
A new metal nitride
Using a diamond anvil cell to create high (up to 50 GPa) pressures, and a laser to create high (up to 2,000 K) temperatures, researchers from Lawrence Livermore National Laboratory (LLNL; Calif.; edlinks.chemengonline.com/5828-543), the Carnegie Inst. of Washington, and the…
Steam Handling
Sodium-ion monitoring can prevent steam-turbine corrosion Studies have shown that sodium is one of the most significant contributors to corrosion within turbines, and that such corrosion leads to cracking, embrittlement and ultimately, turbine failure. The Orion Ionplus 2111LL low-level sodium…
Chementator: Heterogeneous catalyst
A heterogeneous catalyst for producing the solvent methyl isobutyl ketone has been developed by graduate student Ferry Winter, who defended his chemistry Ph.D. thesis last month at Utrecht University (Netherlands; edlinks.chemengonline.com/5827-550). The catalyst is based on activated hydrotalcite — a…
Chementator: A dosimeter monitors long-term exposure to phosgene
Phosgene is widely used for making fine chemicals, pharmaceutical intermediates, and polymers such as isocyanates, polyurethanes and polycarbonates. But phosgene is highly toxic, and although gas detectors are required to monitor for dangerous leaks, they cannot determine if workers have…
Chementator: Mobile water plant
Siemens Industrial Solutions and Services Group (Erlangen, Germany; edlinks.chemengonline.com/5827-551) has built, commissioned and deployed the largest mobile water filtration system in the industry. The Horizontal Filtration Trailer (HFT) has 242 ft2 of filtration surface area and can produce up to…
Chementator: This packing material keeps produce moist, while preventing water contact
A patented moisture-control technology (MCT) developed by CSIRO Plant Industry (edlinks.chemengonline.com/5827-534), with cooperation from Stellar Films Group (both Melbourne, Australia; edlinks.chemengonline.com/5827-535), has shown it can maintain field freshness of selected fruit and vegetables during extended periods of storage and shipping.…
Chementator: Slash water and energy requirements with this dyeing process
The conventional way to dye textiles is by the so-called dip process, whereby cloth is first immersed into a vat of the dying medium, then removed and dried. The dye is then thermally fixed to the textile by heating to…
Chementator: A more-direct route to epichlorohydrin makes its commercial debut
Solvay (Brussels, Belgium; edlinks.chemengonline.com/5827-536) is planning to build a new plant for producing epichlorohydrin at its Tavaux, France, site. When the facility starts up in the first half of 2007, it will produce 10,000 m.t./yr of epichlorohydrin using Solvay’s Epicerol…
Chementator: A ‘litmus’ test for heavy metals
Toshishige M. Suzuki and his colleagues at the Tohoku Center of National Institute of Advanced Industrial Science & Technology (AIST; Sendai, Japan; edlinks.chemengonline.com/5827-538) has developed a new analytical test strip that can quickly detect parts-per-billion (ppb) concentrations of heavy metal…
