Alfa Chemistry Catalysts—an Expert in Catalysts Science
Catalysts are widely used in 90 percent of all commercially produced chemical products. To better meet the ever-increasing demand for catalysts in the market, Alfa Chemistry Catalysts is founded and specialized in providing various categories of catalysts, including chiral catalysts, ligands, metal catalysts, non-metal catalysts, organocatalysts, phase transfer catalysts, photocatalysts, and reaction type.
A catalyst is a substance that is added to a reaction for the purpose of increasing the reaction rate. It is not consumed in the process. Catalysts typically speed up a reaction by reducing the activation energy or changing the reaction mechanism.
The catalysts provided at Alfa Chemistry Catalysts include:
Chiral catalyst refers to a substance, which accelerates a chemical reaction resulting in chiral products from achiral substrates. From a process development viewpoint, catalysis is essential in the production of chiral compounds, because we are always looking for cost-effective and environmentally friendly solutions. Catalysis can offer the possibility of both.
In organic chemistry, ligands are often used to protect other functional groups or to stabilize some readily reactive compounds. Ligands have a wide range of applications in analytical chemistry, industrial production, and biochemistry.
Metal catalyst is one of the important branches of solid catalyst, and one of the earliest and most widely used catalysts. The most commonly used metal catalysts are those of group VIII metals. Metal catalyst can be used for hydrogenation, dehydrogenation, oxidation, isomerization, cyclization, hydrolysis and other reactions.
A non-metallic catalyst refers to a compound that is catalytically active but does not contain metal atoms or metal ions. Non-metal catalysts available at Alfa Chemistry Catalysts include: arsenic catalysts, boron catalysts, nitrogen-containing catalysts, phosphorus catalysts, selenium catalysts, and silicon catalysts.
Organocatalysts are catalysts containing only carbon, hydrogen, sulfur, and other non-metallic elements. Organocatalysts can catalyze a variety of reactions, which can be divided into activation reactions, oxidation reactions, condensation reactions, carbonyl reduction reactions and oxo synthesis reactions according to the catalytic mechanism.
Phase Transfer Catalysts
Phase transfer catalysts (PTCs) are a class of catalysts that can assist in the transfer of reactants from one phase to another that is capable of reacting, thereby accelerating the reaction rate of the heterogeneous system.
Photocatalyst is a general term for chemical substances that can catalyze under the excitation of photons. There are many materials that can be used as photocatalysts, including titanium oxide (TiO2), zinc oxide (ZnO), tin oxide (SnO2), zirconium dioxide (ZrO2), cadmium sulfide (CdS) and other oxide sulfide semiconductors,
