Nickel: A greener route to fatty acids


Chemists designed a nickel catalyst that easily transforms petroleum feedstocks into valuable compounds like fatty acids. The process is environmentally friendly: not only it works at room temperature and atmospheric pressure, but also recycles carbon dioxide, contributing to the fight against ...


E-selective macrocyclic ring-closing metathesis


Using ring-closing metathesis to exploit the properties of carbon-carbon double bonds, researchers from Boston College and the Massachusetts Institute of Technology have developed a new catalytic approach for the preparation of compounds essential to drug discovery. The catalyst, which contains ...


Chevron Phillips Chemical studying NAO expansion at Cedar Bayou Plant


Chevron Phillips Chemical Company LP announced it is studying the possibility of expanding its normal alpha olefins (NAO) capacity – targeting at least a 20 percent increase in a phased approach – at its Cedar Bayou Chemical Complex in Baytown and the company has filed the necessary ...
