Lewis acid catalysis
Louis Catalysis in Organic Chemistry
Organic Chemistry has long been fundamental in understanding the complex reactions involved in organic systems. In many processes, the reactants come together because of the presence of a catalyst. A catalyst is a substance, typically a metal, that accelerates......
Sulfuric acid slag
Introduction
Sulfuric acid slag (SAS) is a byproduct of the sulfuric acid production process. It is composed of fine particles of unreacted raw material, product of the reaction of sulfuric acid and its reaction products, mainly contained in the reaction dioxide (SO2). In the sulfuric acid reacti......
