Plant Watch Evonik to close its orthoesters plant in Niederkassel... June 11, 2008 — Evonik Industries AG will be shutting down its production plant for orthoesters in Niederkassel (Germany) in the 3rd Q of this year. It has been forced to take this step due to overcapacity, the difficult competitive situation and high raw material prices. The site’s most important products are alcoholates...

Ethanol could be produced for less than $1/gal through a new process developed by ZeaChem, Inc. (Lakewood, Colo.; edlinks.che.com/7374-531). The company has piloted the process (flowsheet) and plans to start up a 1.5-million-gal/yr full-scale demonstration plant at the end of 2009, says Jim Imbler, chief executive officer. The process starts with acid hydrolysis of biomass to obtain sugars, as in standard...

Single crystals of high-purity, anatase titanium dioxide with a high percentage of reactive (001) facets are said to have promising applications in solar cells, photonic and optoelectronic devices, sensors and photocatalysis. However, it is the (101) crystal facets of anatase TiO2 that are thermodynamically stable, make up about 95% of a...

Alkylglyceryl ethers (AGEs) are biodegradable nonionic surfactants with excellent foaming and moisturizing properties. Up to now, AGEs have been made in batch reactors whereby the corresponding alkyl glycidyl ether (GE) is hydrolyzed in a solvent (alcohol or ethyleneglycol monoalkyl ether) with a homogeneous acid or base as a catalyst. Such conventional routes leave catalyst residue and solvent in the product...

Current silks tend to lose performance in water and yellow in sunlight. Few of the silk-producing species of insect or spider are amenable to domestication, their silks are difficult to produce using biotechnology, and it is difficult to spin those recombinant silk proteins. The difficulty of reproducing those silks is due to factors...

Titanium, the ninth most abundant metal in the world, has some desirable properties — the highest strength-to-weight ratio of any metal and high-temperature and corrosion resistance. However, its high production cost has so far restricted its use mainly to aerospace applications. A combination of process steps that promises to cut the cost by 50% is being developed by Oak Ridge National Laboratory...

A simple, fast and clean process to make esters without a catalyst is being developed by Chemicrea Inc. (Tokyo; edlinks.che.com/7374-539) with the support of New Energy & Industrial Technology Development Organization (Kawasaki), and Gifu University (Gifu, all Japan). The process uses microwaves to continuously drive off the water byproduct, thereby shifting the reaction equilibrium to the right...

A method for manufacturing porous-wall, hollow-glass microspheres (PWHGMs) over an adjustable range of pore sizes promises to substitute the doped-ceramic packing material employed in various processes, by delivering improved kinetics and a denser, more uniform arrangement of active materials. The research — conducted by the Savannah River National Laboratory (SRNL; Aiken, S.C....

The use of palladium on carbon powder supports (Pd-CP) has traditionally been a commercially viable means of catalyzing deprotection reactions, despite also requiring substantive quantities of precious metal and limiting the selection of solvents due to low hydrogenation activity. However, with a new series of Pd-CP catalysts, BASF’s catalyst division (Iselin, N.J.; edlinks.che.com/7374-541) has...

At 2,064 ft as of this past April, the unfinished Burj Dubai skyscraper in the United Arab Emirates is the tallest man-made structure on earth. "A structure of this kind is only possible if the right [concrete] mixture is guaranteed," as BASF’s executive director for research Stefan Marcinowski has pointed out. In fact, "a chemist with an analytical laboratory is constantly monitoring...
