Product Description:


               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:why are catalysts never used up during reactons?
Catalysts facilitate the reaction. They might work in several ways. Here is an example: Catalysts generally react with one or more reactants to form intermediates that subsequently give the final reaction product, in the process regenerating the catalyst. The following is a typical reaction scheme, where C represents the catalyst, X and Y are reactants, and Z is the product of the reaction of X and Y: X + C → XC (1) Y + XC → XYC (2) XYC → CZ (3) CZ → C + Z (4) Although the catalyst is consumed by reaction 1, it is subsequently produced by reaction 4, so for the overall reaction: X + Y → Z They might also just increase the surface area, thus speeding up the reaction. Example: Coke looses its fizz over time if left with the cork unscrewed. This is because the HCO3 is released as CO2. If you drop a menthos into the coke, it explodes with CO2, because the methos is full of tiny dents in the surface (thus giving it a massive surface area). (i blatantly copied the first example from the wiki)
Q:How the catalyst accelerates the chemical reaction
Add pigments
Q:What is positive and negative catalyst in chemistry?
Negative catalysts are, on the other hand, slowing down the positive reaction rate at the same time
Q:What is the principle of catalyst reaction rate in chemical reactions?
Whether the chemical reaction can be carried out according to the change of free energy, but only according to the change of free energy can not determine whether the reaction can be completed, because the chemical reaction is also completed by the reaction of the energy barrier, that is, if the reaction energy barrier is high, To provide some energy, across the barrier, to complete the reaction. The energy barrier is called activation energy. And the role of the catalyst is to reduce the activation energy, so that in a relatively harsh environment, chemical reaction occurs.
Q:What are the catalysts for making oxygen in chemistry? (At least 8 listed)
Manganese dioxide, iron oxide (red brick powder), copper oxide, ferrous oxide, iron oxide, activated carbon, egg shell, fresh liver, raw potato chips, etc.
Q:Is the catalyst in the chemical reaction better?
No, you can. Too much useless
Q:Why are transition metals more likely to be catalysts?
there are so much catalysts made up of transition metals. because one of the characteristics of transition metals is can be made to catalyst. one of the catalyst that is mostly used is iron fillings which is used as catalyst to make ammonia from nitrogen gas and hydrogen gas.
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
Q:What is the PTC catalyst in chemistry?
PTC, Phase Transfer Catalyst, phase transfer catalyst PTC is the role of a reaction from one phase to another phase to participate in the reaction to promote a solvent can be dissolved in organic solvents and a solvent insoluble in the ion Reagents react between the two reagents. And this type of reaction is collectively referred to as phase transfer catalytic reaction.
Q:What is the role of the catalyst in chemical knowledge?
Positive catalyst is to speed up the negative catalyst to slow down some reaction must be used to the catalyst otherwise difficult to react
