In ball milling, the chemicals and a steel ball are placed into steel jars which are then shaken vigorously. Credit: Hokkaido University Researchers have shown mechanical force can start chemical reactions, making them cheaper, more broadly applicable, and more environmentally friendly than conventional...
Rational pathway engineering of type I fatty acid synthase allows the biosynthesis of triacetic acid lactone from D-glucose in vivo. Metabolic pathway engineering is a powerful tool to synthesize structurally diverse and complex chemicals via genetic manipulation of multistep catalytic s... W Zha,Z ...
Using turbine expanders to recover exothermic reaction heat for the combined production of power and chemicals Many reactions carried out in the chemical industry are exothermic. The heat liberated by the reaction is often transferred to another medium such as steam by heat exchange. This heat can...
Caprolactam (CPL) is a widely used chemical intermediate for producing Nylon 6 fibers with its annual consumption exceeding 3.4 million tons. UCL at ITRI has collaborated with Acelon Chemicals and Fibers Corp in developing a new process technology for CPL production from butadiene. The overall CPL...

"When supercritical water is mixed with organic material, a chemical reaction takes place—oxidation." Says Hicks. "It's a form of burning without flames." This really comes in handy when you want to get rid of certain unpleasant materials—like sewage. Cities, corporate farms, ships at sea...
UN ID:UN ID is the harm identifier number value useful for determining hazardous and flammable chemicals. This number comes in four-digit, ranging from UN0001 to about UN3500. And assigned by the United Nations Committee of Experts on the Transport of Dangerous Goods. The other alternate names...
The present invention relates to the production of alkylbenzaldehydes which are useful as raw materials or intermediates for perfumes, medicines and agricultural chemicals, more particularly, to the production of alkylbenzaldehydes from alkylbenzenes having a primary alkyl group of two or more carbon ...
LA represents a valuable intermediate for the synthesis of several chemicals for application in fuel additives, fragrances, solvents, pharmaceuticals, and plasticizers [8–13]. LA, also known as 3-acetylpropionic acid, 4-oxovaleric acid, or 4-oxopentanoic acid, is a very interesting platform ...
