Ziegler-Natta catalysts are effective in polymerizing hydrocarbons with double bonds. The three types are solid and titanium-supported, metallocene, and non-metallocene. They help control the tacticity of vinyl and are major catalysts used in plastic manufacturing. Karl Ziegler discovered the titanium-based catalyst, while Giulio Natta discovered the other two. A Ziegler-Natta catalyst is one of the […]
Cisco’s Catalyst® switch is an Ethernet or network switch that can inspect, process and redirect data traffic. It can function as a hub, router switch, network switch or Ethernet switch, and offers modularity and redundancy. It can also provide interfaces with T1, E1, and various WANs and may offer PoE. A Catalyst® switch is part […]
Sulfuric acid is a catalyst used in the production of various products, including nylon and fuel additives. It donates protons to reactants, lowering the activation energy and creating low energy reaction intermediates. It is chosen for its availability and low cost. A sulfuric acid catalyst is the chemical compound containing hydrogen, sulfur and oxygen, with […]
A catalyst speeds up chemical reactions by lowering the activation energy required. It can be organic, synthetic or metallic. Enzymes are specialized proteins that act as catalysts in biochemical reactions. Catalysts are also important in industry, such as the catalytic converter in cars and fertilizers for plant growth. Inhibitors are negative catalysts that slow down […]
Zinc oxide is used as a catalyst in various industries, including rubber manufacturing, construction, and pharmaceuticals. It is also used in the production of ethanol from biomass and in the chemical production of ketones. Zinc oxide is nontoxic and can act on organic and inorganic materials. It is sold in various formulas for different applications. […]
Heterogeneous catalysts participate in chemical reactions in a different phase than the reactants, often using precious or transition metals. They increase reaction rates by altering the transition state and are easily recoverable, making them useful in continuous processes like the petroleum industry’s “moving bed” process. The term “phase” refers to the state of matter; there […]
Catalysts speed up reactions without being consumed. Homogeneous catalysts are in the same phase as reactants, while heterogeneous catalysts are exposed to a solid substrate. Organometallic compounds are used as homogeneous catalysts in complex chemistry, such as polymerization and pharmaceutical manufacturing. They are also being studied for artificial photosynthesis. In chemistry, a catalyst is a […]
