Chemical Technology In Antiquity

Chemistry is intimately involved in the development of the oldest known civilizations, resulting in a range of chemical technologies that not only continue to be part of modern civilized societies, but are so commonplace that it would be hard to imagine life without them. Such chemical technology has a very long and rich history, in some cases dating back to as early as 20,000 BCE.


Managing Hazardous Reactions And Compounds In Process Chemistry

There is always potential for hazards during chemical reactions that can lead to accidents resulting in loss of time, equipment, products and harm to people. The hazards may result from uncontrolled exothermic reactions or secondary exothermic reactions such as decomposition of a reactant, reagent or product. Hazards may also occur from impurities or metal residues that can catalyze undesire
