Molecular Formular : C24H38O4
Molecular weight : 390.57
CAS No.:117-81-7
H.S Code : 2917.3200.00
EINECS No.: 204-211-0
Characteristics : Colorless transparent oily liquid, slight odor.
Processing : Injection Moulding
Application : It is one of the most extensively used plasticizers in plastics processing. It has comprehensive properties, such as high plasticizing efficiency, low volatility, UV-resisting property, water-extracting proof, cold-resisting property, and also good softness and electric property. As a fine main plasticizer, it is extensively used in processing polyvinyl choride and ethylcellulose resins to produce plastic film, imitation leather, electric wire, cable wearer, sheet, planet, mould plastic products and. Used in nitrocellulose paints, it can make the ethylcellu lose more elastic and more strong in extracting tension. It can be used as a softening agent of synthetic rubber, such as to make the product easier to rebound and harder to undergo form change under pressure, without affecting of the plastics.

- Q: What is the superiority of the catalyst compared to the stoichiometric reagent?
- Some enzymes are related to cofactors, and because of the fact that most enzymes are proteins, they are destroyed by high temperatures, strong acids and strong bases.
- Q: in acid-catalyzed reaction,there are some books show the acid catalyst as H+ and there are some show it as H3O+ .Are they the same?
- H+ is the ion contained in acids.... When acids are dissolved in water (H+)+(H2O)=H3O+ Both are the same......
- Q: Is the reaction of the exhaust purification of cars (carbon monoxide and nitrogen
- Can not react
- Q: Also, how is the catalyst affected by heat? Please answer all of the questions not just one of the three. THANK YOU!
- It denatures the catalyst because the rise in pH or amount of H3O+ ions. Temperature will also denature the catalyst if it's out of its optimum range.
- Q: What is the difference between an enzyme catalyst in a living body and a catalyst in chemistry?
- enzyme susceptibility inactivation Chemical catalyst under certain conditions, due to poisoning and loss of catalytic capacity; and enzyme than the chemical catalyst is more fragile, more volatile activity. Any factor that makes the protein degenerate (to strengthen the acid, alkali, high temperature, etc.), can make the enzyme completely lost activity.
- Q: Why does the chemical and chemical properties change before and after the reaction?
- At present, the role of the catalyst has not yet fully understood. In most cases, it is believed that the catalyst itself and the reactants participate in the chemical reaction, reducing the activation energy required for the reaction. Some catalytic reactions are due to the formation of a very easy decomposition of the "intermediate", the decomposition of the catalyst to restore the original chemical composition, the original reactant becomes a product. Some catalytic reactions are due to adsorption, adsorption can only be in the catalyst surface of the most active area (called the active center) carried out. The greater the area of the active site, the greater the activity of the catalyst. Reactants such as impurities,
- Q: Why can some catalysts be reused in (chemistry)?
- Because the catalyst in the chemical reaction before and after the quality and chemical properties have not changed, so in the chemical reaction can be reused.
- Q: Explain how catalysts help to reduce costs in industrial processes !?Thanks
- They speed up a reaction, allowing you to get more product more quickly and remain unchanged, therefore you can use them over and over again.
- Q: how a catalyst can provide a new route in forming the product?
- a catalyst does not provide a new route. it just lowers something called the energy of activation of the reaction. this makes some changes in the thermodynamics and kinetics of the reaction
- Q: give an example of how a catalysts speeds up the rate of reaction?? thank you!!?
- Catalysts speed up a reaction, but at the end of it, it's chemically unchanged. You usually have the same mass at the end of the reaction. For example.. Consider the decomposition of Hydrogen Peroxide: 2H2O2 -2H2O + O2 I hope you got how to represent it =D So.. This reaction is very slow. You can try it out in the lab. So when we add a catalyst, the reaction speeds up. The catalyst used here is MnO2.. Manganese dioxide. Well.. The Enzymes in our body are also Catalysts. They speed up the Biological Reactions taking place inside out body. I hope this answers your question. :) Cheers
