The catalyst commonly used in making polyesters is an esterification catalyst, such as an acid catalyst like sulfuric acid or an organic acid like p-toluenesulfonic acid. These catalysts help facilitate the reaction between the diol and the dicarboxylic acid to form the polyester polymer.

Which process is iron used as catalyst?
Iron is used as a catalyst in the Haber process, which is the industrial method for producing ammonia from nitrogen and hydrogen gases. The presence of iron catalyst helps to increase the rate of the reaction and improve the yield of ammonia.
What happens to a catalyst after a reaction?
In any reaction, a catalyst is never used up or changed. This means that at the end of every reaction you should always get your catalyst back. sometimes in the course of the reaction, the catalyst is used up, but by the end of the reaction it will always be reformed completely.
Is a catalyst used up in a reaction?
Yes, a catalyst can be re-used, because It is NOT actually used in a chemical reaction. A catalyst will increase the rate of reaction by attracting reactants, but the catalyst is not a reactant. However, the reuse cannot be done indefinitely then, depending on the severity of the reaction conditions, it can be occur a small, but accumulative deactivation of the catalys.
Why is the catalyst made porous?
By making the pellets porous, you maximize the surface to volume ratio of the catalyst, which allows you to use less of it, but get the same effect.
How can calculate Turnover number of catalyst?
The turnover number of a catalyst is calculated by dividing the total amount of product formed by the catalyst during a reaction by the total amount of catalyst used. This can help determine the efficiency of the catalyst in converting reactants to products.
Is polyesters thermoplastic?
Polyesters are a group of organic polymers that contain the ester functional group in their main chain. Polyesters can be either thermoplastic or thermoset, depending on the rest of their structure, but the most common polyesters are thermoplastic.
What is the catalyst used for making sulphuric acid?
The catalyst used for making sulphuric acid is vanadium pentoxide (V2O5). It helps to speed up the reaction between sulfur dioxide and oxygen to form sulfur trioxide, which is a crucial step in the production of sulphuric acid.
Which process is iron used as catalyst?
Iron is used as a catalyst in the Haber process, which is the industrial method for producing ammonia from nitrogen and hydrogen gases. The presence of iron catalyst helps to increase the rate of the reaction and improve the yield of ammonia.
What is a catalyst only used in photosynthesis?
Chlorophyll is the catalyst that is used in the process of photosynthesis.
Can you reuse the used catalyst?
Yes. it is a part of recycling of catalyst.

A substance which helps a reaction to take place but that does not take an active part is a?
A substance which helps with chemical reactions, by making them possible at all, or reducing the effort required, is a catalyst.
Why is an iron catalyst used when making ammonia?
An iron catalyst is used in the Haber process to synthesize ammonia from nitrogen and hydrogen gases because it speeds up the reaction by providing a surface for the gases to react on. This increases the rate of ammonia production without being consumed in the process, making it an efficient and cost-effective choice.
Is a catalyst used up in a reaction?
Yes, a catalyst can be re-used, because It is NOT actually used in a chemical reaction. A catalyst will increase the rate of reaction by attracting reactants, but the catalyst is not a reactant. However, the reuse cannot be done indefinitely then, depending on the severity of the reaction conditions, it can be occur a small, but accumulative deactivation of the catalys.
Which catalyst is used for peg 6000 ds?
I am unsure, but I think the catalyst is AgCl.
What is an example of a reaction that needs a catalyst and name the catalyst used?
For example the ammonia production; the magnetite catalyst is the most common.
