Reactive oxygen species — (ROS) are ions or very small molecules that include oxygen ions, free radicals, and peroxides, both inorganic and organic. They are highly reactive due to the presence of unpaired valence shell electrons.ROS form as a natural byproduct of the… … Wikipedia
Reactive distillation — is a process where the chemical reactor is also the still. Separation of the product from the reaction mixture does not need a separate distillation step, which saves energy (for heating) and materials.This technique is especially useful for… … Wikipedia
Reactive magnesia — is also variously known as caustic calcined magnesia, caustic magnesia or CCM. The temperature of firing has a greater influence on reactivity than grind size as excess energy goes into lattice energy.Crystalline magnesium oxide, or periclase,… … Wikipedia
Reactive dye — In a reactive dye a chromophore contains a substituent that is activated and allowed to directly react to the surface of the substrate. HistoryReactive dyes first appeared commercially in 1956, after their invention in 1954 by Rattee and Stephens … Wikipedia
