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:In chemistry what is a catalyst and an example?
Catalysts are substances that increase the rate of a reaction by providing a low energy shortcut from reactants to products. In some cases, reactions occur so slowly that without a catalyst, they are of little value. Nearly all reactions that occur in living cells require catalysts called enzymes- without them, life would be impossible. There are two important classes of catalysts: homogenous catalysts like enzymes and aqueous ions that are uniformly mixed with the reactants, and heterogeneous catalysts that provide a surface that holds and reconfigures the reactants in a way that is favorable for reaction. Examples of homogeneous catalysis. Catalysts in solution with the reactants usually provide fast reaction paths by allowing reactants to form an unstable intermediate that quickly decomposes into products. For example, the substitution reaction CH3CH2OH(g) + HCl(g) H2SO4 ----->CH3CH2Cl + H2O(ell) is catalyzed by acid because the ethanol is converted into unstable CH3CH2OH2+, which quickly reacts with Cl- to produce the products. Definition: A catalyst is a subtance that increases the rate of a chemical reaction by reducing the activation energy, but which is left unchanged by the reaction. Examples: A piece of platinum foil is a catalyst for the combustion of methane in air.
Q:What is the quality of the catalyst in the chemical reaction,and how much is the catalyst mass?
You can not calculate this question, the quality of the catalyst before and after the same reaction, how much reaction before the reaction on how much
Q:What are the differences between biological catalysts and chemical catalysts?
One occurs in biological systems and the other is in chemical reactions. Biological catalysts are basically enzymes - proteins which regulate biochemical reactions whilst chemical catalysts act on non-biological chemical reactions and are inorganic elements or compounds.
Q:Chemical reactions in the presence of impurities will cause catalyst poisoning
Catalyst poisoning reaction of raw materials contained in the trace impurities to the catalyst activity, selectivity significantly decreased or lost phenomenon. The nature of the poisoning phenomenon is a trace of impurities and the catalytic activity of the center of a chemical effect, the formation of non-active species. In the gas-solid heterogeneous catalytic reaction is formed in the adsorption complex. One is that if the toxic and active components of the role of weak, can be a simple way to restore the activity, known as reversible poisoning or temporary poisoning. The other is irreversible poisoning, it is impossible to restore the activity in a simple way. In order to reduce the side reaction activity, it is sometimes necessary to allow the catalyst to be selected for poisoning.
Q:Why can some catalysts be reused in (chemistry)?
Because the catalyst in the chemical reaction before and after the quality and chemical properties have not changed, so in the chemical reaction can be reused.
Q:What is a catalyst/catalase? help?
A catalyst is a chemical which speeds up a reaction but without being used up in the reaction, so can be used over again. Catalase is an example of an enzyme which are biological catalysts ie speed up reactions in cells. Enzymes are specific and the enzyme catalase breaks down hydrogen peroxide to water and oxygen. A catalyst which also breaks down hydrogen peroxide is manganese dioxide.
Q:A biological catalyst or a chemical reaction facilitator is know as a/an?
organic and organic catalyst is called ENZYME. A chemical reaction facilitator is called Catalyst A organic and organic molecule that aids enzimes paintings is called Cofactor despite if it extremely is metallic or coenzyme if its organic and organic in foundation.
Q:The quality and nature of the catalyst before and after the chemical reaction did not change this sentence wrong?
There is no wrong catalyst just to speed up the reaction
Q:Chemical catalyst poisoning situation
In the reactants or catalyst mixed with a small amount of material, so that the catalyst catalytic capacity of a sharp decline or even loss, this phenomenon is called catalyst poisoning. For example, in the synthesis of ammonia feed gas containing CO, CO2 and H2S, PH3, water vapor and other impurities, can make iron catalyst poisoning; contact with the system of sulfuric acid, if arsenic and selenium oxide (As2O3, SeO2), can make vanadium catalyst Loss of activity. Therefore, it is necessary to purify the feed gas, prevent the poisoning of the catalyst, and also reduce the corrosion of the equipment. The phenomenon of catalyst poisoning is sometimes temporary, the removal of toxicants, the effectiveness of the catalyst can still be restored; sometimes it is permanent, without chemical treatment can not restore catalytic performance.
Q:Catalyst - Can it decrease the rate of a reaction?
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.
