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: High chemistry: Does the catalyst affect the heat and heat of the reaction?
- The catalyst that has no effect affects only the rate of reaction
- Q: No one knows the expression of the catalyst and the chemical expression of the acridine
- In organic reactions, the catalyst is complex and consists of several or more. Write Chinese characters directly.
- Q: What is the maximum impact of the chemical reaction rate? Such as catalyst, temperature, concentration. If you can, you can row order.
- The catalyst certainly affects the most
- Q: How does catalyst aid a chemical reaction?
- A catalyst will lower the activation energy of a reaction, and hence allow it to happen faster. The actual mechanisms vary widely. Two mechanisms are: 1/ formation of intermediate compounds, which can then decompose into the catalyst and the required product 2/ provision of a large surface area for adsorption, so the reactant molecules can come into contact sooner.
- Q: a) A catalyst such as chlorophyll must be present for some reactions to take place.b) A catalyst such as chlorophyll is not one of the products of a chemical reaction.c) A catalyst such as chlorophyll is not a substance that is used or changed in a chemical reaction.
- (c) fairly catalyst varies the path of reaction or u can say mechanism of reaction in which activation ability receives decrease hence of which fruitful collisions occurred at extremely decrease temperature so greater beneficial opportunities for molecules to bypass activation complicated a catalyst is a substance that lowers the activation ability of a chemical reaction yet itself final unchanged in the process the time of the reaction
- Q: The size of △ H in the thermochemical reaction equation is related to the use and unused catalyst
- There is no relationship between the catalyst can only change the reaction rate
- Q: How are a catalyst and an intermediate similar? How are they different?
- A catalyst speeds up the rate of a reaction by lowering the activation energy barrier which is, presumably, the energy required to achieve the reaction intermediate. Catalysts are also not consumed in the reaction, they are regenerated towards the end. A reaction intermediate is a configuration that a molecule takes prior to achieving it's lowest energy form which would signify the end of the reaction. Intermediate usually are hard to isolate because of the incentive to go to the most stable configuration. How are they different? A catalyst is not a part of the reaction product and it doesn't get consumed. An intermediate in a reaction is transformed into the product. How are they similar? Well, catalysts drive the reaction and make it easier for the reaction for follow through. Since intermediates are high energy and thermodynamics tells us that low energy is favorable, the incentive for a high energy intermediate to drive down to it's stable for can also drive a reaction. I hope that helps. I hope it makes sense.
- Q: The quality and nature of the catalyst before and after the chemical reaction did not change this sentence wrong? Why did the "middle school student study" say it was wrong?
- There is no wrong catalyst just to speed up the reaction
- Q: Is it not the rate to accelerate the addition of the catalyst to the catalyst, and that is why the balance does not move
- In the chemical equilibrium, after adding the catalyst, the positive and negative reaction rate increases equally, but the positive reaction rate is still equal to the reverse reaction rate, so the balance does not move
- Q: Chemical reactions in the presence of impurities will cause catalyst poisoning, how to understand this sentence
- This is in the chemical balance, but also alone
