Home > Catalyst and Auxiliary
According to the catalyst definition by the International Union of Pure Chemistry and Applied Chemistry (IUPAC) in 1981, a catalyst is a substance that alters the reaction rate without affecting the Gibbs free energy of the overall standard reaction. Catalysts span diverse types: liquid and solid catalysts based on state, and homogeneous versus heterogeneous catalysts based on phase state within the reaction system. In industrial processes, auxiliaries like centrifuge catalysts enhance production processes, improve product quality, or enable specific application performance. The array of auxiliaries definition is extensive, with varied performance - optimal effects stem from proper usage. ECHEMI's "Catalyst and Auxiliary" section predominantly supplies raw materials for Catalyst and Auxiliary.

Frequently Asked Questions

How to choose the right catalyst for your application?

When selecting a catalyst, it is important to consider the type of reaction, operating temperature, pressure, solvents involved, and desired selectivity. Other key factors include catalyst lifetime, regeneration ability, and compatibility with your process. On ECHEMI, you can browse a wide range of catalyst and auxiliary products and compare specifications from multiple global suppliers to find the best option for your needs.

What is a catalyst?

Synonyms for catalyst include accelerator, promoter, stimulant, etc. A catalyst is a substance that speeds up a chemical reaction without undergoing any permanent changes. According to the catalyst definition, it doesn't alter the thermodynamics or the catalyst meaning of the reaction, but it lowers the activation energy required for the reaction to occur. Basically, a catalyst facilitates the reaction process and increases the conversion rate without being consumed in the reaction itself. It may exist in a variety of forms, including enzymes, metals, or complex compounds.

How does a catalyst work?

The function of a catalyst is to provide an alternative pathway for a chemical reaction to take place. It reduces the activation energy required for the reaction to begin, thus speeding up the rate of the reaction. The catalyst apex is the point at which the catalyst's effect on the reaction reaches maximum efficiency. It diminishes existing chemical bonds or establishes intermediary structures, so simplifying the reaction process, consequently expediting the production of substances. This mechanism, often utilized by catalyst companies, leads to accelerated product formation.

Are enzymes catalysts?

Yes, according to the catalyst definition, enzymes are biological catalysts. Enzymes, considered protein-based catalyst synonym, facilitate biochemical reactions within living organisms. Within defined temperature and pH parameters, enzymes function as exceedingly efficient catalysts, diminishing the activation energy necessary for reactions to occur. These auxiliaries, when integrated into biological systems, demonstrate specificity and selectivity in catalyzing particular reactions, rendering them pivotal as key catalysts across diverse biological processes.
