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:In the chemical calculation, the quality of the catalyst should not be counted before and after the reaction
- Half is not easy to save trouble
- Q:Are the catalysts for upgrading the weapons components that i may have a few of, or very rare ones?
- Catalysts can only be used when the item is ready to evolve. On top of that you can't use a different kind of catalyst than the one actually require and you can't use too many or too few. Catalysts are basically automatic as long as you have enough, all you can do is choose to use them. On the other hand, you CAN accidentally use sells for a premium as a material. Those items are universally horrible as a material, but sell really well in the shop. Don't use them by accident, sell them as soon as you can.
- Q:What is the principle of the catalyst? Why can change the rate of chemical reactions and their own without any change
- Because the catalyst does not participate in the reaction, it can change the rate of chemical reactions without any change in itself.
- Q:A catalyst elevates the rate of a reaction by?
- reducing the energy required for the reactants to reach the transition state.
- Q:Does the catalyst affect the chemical reaction rate constant? How does the chemical reaction rate constant change when a positive catalyst is added to a reaction?
- The catalyst will change the rate constant
- Q:Can you describe at least 4 ways a catalyst can lower the activation energy of a reaction?
- To see how a catalyst accelerates the reaction, we need to look at the potential energy diagram shown below which compares the non-catalytic and the catalytic reaction. For the non-catalytic reaction, the figure is simply the familiar way to visualize the Arrhenius equation: the reaction proceeds when A and B collide with succificient energy to overcome the activation barrier. The change in Gibbs free energy between reactants, A + B, and the product P is delta G. The catalytic reaction starts by bonding of the reactants A and B to the catalyst, in a spontaneous reaction. Hence, the formation of this complex is exothermic and the free energy is lowered. There then follows the reaction between A and B while they are bound to the catalyst. This step is associated with an activation energy; however, it is significantly lower than that for the uncatalyzed reaction. Finally, the product P seperates from the catalyst in an endothermic step. The energy diagram illustrates 4 ways the catalyst works : The catalyst offers an alternative path for the reaction that is energetically more favorable The activation energy of the catalytic reaction is significantly smaller than that of the uncatalyzed reaction; hence the rate of the catalytic reaction is much larger The overall change in free energy for the catalytic reaction equals that of the uncatalyzed reaction. Hence, the catalyst does not affect the equilibrium constant for the overall reaction. A catalyst cannot change the thermodynamics of a reaction but it can change the kinetics. The catalyst accelerates both the forward and the reverse reaction to the same extent. In other words, if a catalyst accelerates the formation of product P from A and B, it will do the same for the decomposition of P into A and B.
- Q:Can a catalyst decrease the rate of a chemical reaction? Please give an example if yes.
- A catalyst is something that quickens the fee of reaction without getting used up itself. They many times try this by skill of lowering the activation skill, which additionally brings the optimal temperature down. So, to place it only, it relatively is B.
- Q:Now, i am studying for my biology exam in 3 weeks time...i stumbled upon catalase, and then checked my book its catalyst...now im confused...is there a different among these 2 terms? i think..catalyst is the when a substance brings up or about a chemical reaction without using itself up and then catalase breaks down the toxic by-product of metabolism, hydrogen peroxide, into water and oxygen.Or am i wrong?please explain what is catalyst and catalase in biology or are they the same, just differently?
- Catalysts and catalase are two different things, and the definitions that you listed are correct. A catalyst is something that speeds up the rate of a chemical reaction. Many chemical reactions occur naturally and do not require any energy, but they occur so slowly that they are not useful, and catalysts can be used in cases like this to speed up the process. For example iron metal exposed to oxygen and water turns to rust, but if you need a lot of rust by tomorrow, leaving a chunk of iron out in the rain is not a practical solution because it will take too long to convert all that iron metal into rust.
- Q:The chemical equation of heating reaction of benzene and hydrogen under the action of catalyst
- C6H6 benzene + 3H2 - (arrow) C6H12 cyclohexane (Ni catalytic heating)
- Q:I have just spent CAN$550 to replace a catalyst converter at one end of the muffler. The repairman said I need to replace the oxygen sensor very soon, otherwise, the C.C. will be gone again. Is that true... can someone confirm this for me. Thanks.
- your O2 sensor measures the amount of oxygen remaining in the exhaust gas after the combustion process. The left over oxygen reacts with the sensor to send an electrical signal to your vehicles computer. the computer can then adjust your fuel injector pulse width in order to maintain the proper 14.7:1 air/fuel ratio. Excessive exhaust gases are the usual culprit when catalatyc converters fail. Even so the O2 sensor is usually fairly cheap ($20-$30) and simple to replace. I would replace it as cheap insurance
