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:Palladium is the main catalyst in chemistry?
- Palladium in the chemical mainly to do the catalyst; palladium and ruthenium, iridium, silver, gold, copper and other alloy, can improve the palladium resistivity, hardness and strength, used in the manufacture of precision resistors, jewelry and so on. While the most common and most commercially available palladium jewelery is palladium.
- Q:the heterogenous catalyst ZSM-5 IS used to convert ?
- Zeolite-based heterogeneous catalysts are used by industrial chemical companies in the interconversion of hydrocarbons and the alkylation of aromatic compounds. A very good example is the zeolite ZSM-5. This zeolite, developed by Mobil Oil, is an aluminosilicate zeolite with a high silica and low alumininum content. Its structure is based on channels with insecting tunnels. The aluminium sites are very acidic. The substitution of Al3+in place of the tetrahedral Si4+ silca requires the presence of an added postive charge. When this is H+, the acidity of the zeolite is very high. The reaction and catalysis chemistry of the ZSM-5 is due to this acidity. The ZSM-5 zeolite catalyst is used in the petroleum industry for hydrocarbon interconversion. An example use is in the isomerizations of xylene- from meta to para-xylene. The acidic zeolite promotes carbocation isomerizations. There are two suggested mechanisms for this type of isomerizations. Firstly shape may play a role. Perhaps para-xylene has a shape which allows it to diffuse rapidly through the zeolite structure, whereas as meta-xylene takes longer to pass through the zeolite and thus has more opportunity to be converted into the para-xylene. Secondly, is that the orientation of reactive intermediates within the zeolite channels favors specifically para-xylene.
- Q:Does the catalyst participate in chemical reactions?
- The catalyst only acts as a catalyst in the chemical reaction and does not participate in the chemical reaction
- Q:What are the characteristics of the catalyst in the chemical reaction?
- In simple terms: the catalyst itself is involved in the reaction, the quality of the reaction before and after the same, the ingredients do not change. The catalyst can change the rate of chemical reaction, increase the rate of reaction called catalyst, slow the inhibitor.
- Q:okay im doing a project for my classroom about catalyst and i have to draw a picture but when i looked up on google i just saw a bunch of random stuff and a couple were metal so thats why im asking this question. :)
- A catalyst most often is a metal in the form of a screen or sponge with lots of area although it can be an immiscible liquid or sand like particles that can be filtered out.
- Q:What is a chemical catalyst?
- A substance that participates in chemical reactions but does not change the quality and chemical properties. It can change the reactant activation energy, speed up or slow down the reaction rate.
- Q:Chemical "catalyst can speed up the chemical reaction rate of other substances," this sentence right?
- Wrong, the catalyst is divided into two kinds, one is to speed up the chemical reaction speed, and the other is the opposite
- Q:What happens to a catalyst after a chemical reaction?
- Only a catalyst? Poor catalyst. Catalysts get very little respect. Folks assume that catalysts don' do anything, yet they magically speed up a reaction without taking part in the reaction. That just isn't the case. Most chemical reactions take place in multiple steps. A catalyst can be a reactant in one step and a product in s subsequent step, thereby giving the impression that it did not react. The catalyst speeds up a chemical reaction by providing an alternate reaction pathway which has a lower activation energy. The lower activation energy means that more molecules will have the energy required to react, and the rate will be greater. So the bottom line is that the catalyst will have appeared not to have reacted, and returns to its original 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 positive catalyst will increase the constant, negat
- 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
