DOP
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: The best use of chemical catalysts
- Do not know what you want to use the best thing is what the catalyst is generally used in the process, there will be an initial induction period, the catalytic activity is relatively low, and then reached a stable catalytic state, this paragraph is generally called the catalyst life, the final Due to poisoning, active ingredient aggregation and so on factors, the catalyst activity will be reduced, then need to replace the new catalyst
- Q: Could you tell me all the differences between those two catalysts? Thank you very much.
- Biological catalyst: 1. Biological catalysts or enzymes are high molecular weight globular proteins. 2.Their composition may change at the end of reaction. 3.Their catalyzing effect is very high. i.e faster than chemical catalyst. 4.They are reaction specific. i.e One enzyme or biological catalyst may catalyze only particular type of reaction and not many. 5.They are intolerant to temperature and pH changes. An enzyme can not function outside its temperature or pH range. e.g amylase,lipase,pepsin Chemical catalyst: 1.Chemical catalysts are simple inorganic molecules with low molecular weight. 2.They remain unchanged at the end of reaction. 3.They are slower compared to enzymes. 4.They are not reaction specific. 5.They function within wide range of temperatures,pH or pressure. e.g vanadium dioxide, platinum
- Q: How does catalyst aid a chemical reaction?
- it makes the reaction go faster.
- Q: What is the difference between electrocatalysis and general chemical catalysis?
- General chemical catalysis is a catalyst, and electrocatalysis also need to be carried out under the conditions of the electric field
- Q: Please help me
- enzymes are like chemical scissors that break up starch inside your body they work best at 37'c which is body temperatur i think they are in the stomach? don't know for sure hope this helped as for catalysts i dont know
- Q: Comparison of biocatalysts with chemical catalysts!
- (1) The chemical reaction catalyzed by the biological enzyme is generally carried out under relatively mild conditions. (2) The enzyme has the highest activity at the optimum temperature and pH, and the temperature of the biocatalyst is more moderate. And PH high or low, the enzyme activity will be significantly reduced.In general, the animal in the enzyme the optimal temperature between 35 ~ 40 ℃; plant enzyme in the optimal temperature between 40 ~ 50 ℃; animal body Of the enzyme most of the most suitable pH between 6.8.0, but there are exceptions, such as the optimal pH of pepsin 1.5; plant enzymes in the most suitable pH between 4.6.5. (3) acid, Or the temperature is too high, the enzyme structure will be destroyed, so that the enzyme permanently inactivated .0 ℃ or so, the enzyme activity is very low, but the spatial structure of the enzyme is stable, at the appropriate temperature of the enzyme activity can be increased The
- Q: What is the difference between a catalyst and an oxidizing agent?
- a catalyst DOES NOT take part in the reaction. it merely speeds it up. Without a catalyst, the reaction would still occur, just slower. However, reactions with oxidizing agents CANNOT and WILL NOW take place without them. They gain electrons and are also considered the thing that is reduced. At the end of the reaction, they have been altered in some way, unlike catalysts.
- Q: In the chemical reaction, the rate of decomposition reaction is related to the quality of the catalyst?
- The catalyst can affect the reaction rate, the faster the amount of reaction or slower. Of course there are limits,
- Q: Write a chemical formula in a chemical laboratory without the use of a catalyst for oxygen
- 2KMnO4 = Δ = K2MnO4 + MnO2 + O2 ↑
- Q: What is the catalyst called?
- Junior high school book definition: in the chemical reaction can change the chemical reaction rate of other substances, and its own quality and chemical properties before and after the reaction did not change the material called catalyst, also known as catalyst. The role of the catalyst in the chemical reaction is called catalysis.
