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:What is the difference between a catalyst and an inducer in a chemical reaction?
- The catalyst does not participate in the reaction, but only the carrier of the reaction; the inducer will participate in the reaction
- Q:give an example of how a catalysts speeds up the rate of reaction?? thank you!!?
- When making margarine, nickel is used to speed up the process.
- Q:What is the catalytic efficiency of ordinary chemical catalysts?
- Different reactions, with the same catalyst, the catalytic efficiency is different. The same reaction, with different catalysts, the catalytic efficiency is also different
- Q:Nitrogen and hydrogen in the role of high temperature and pressure catalyst to generate ammonia chemical equation
- N2 + 3H2 = catalyst, high temperature and high pressure = 2NH3
- Q:Can the catalyst be a reactant in chemistry?
- There is also a saying that the catalyst participates in the chemical reaction. In a general chemical reaction, the effect of the catalyst is to reduce the activation energy required for the reaction to occur, essentially to turn a more difficult reaction into two, In the second reaction, the catalyst in the first reaction plays the role of the reactant, and the catalyst in the second reaction plays the role of the product, so that the catalyst is not present before and after the reaction Variety.
- Q:What is the catalyst in the end?
- You said the chemical catalyst or Ati graphics card catalyst? If the above is enough to explain the above, if it is the latter, that is, the meaning of the graphics card, Ati's graphics drive like a catalyst
- Q:What is the catalyst for industrial aluminum electrolysis?
- 2AlCl3 (melt) = power = 3cl2 + 2al by-product is chlorine
- Q:Why does the chemical and chemical properties change before and after the reaction?
- The catalyst will induce chemical reactions to change, leaving the chemical reaction faster or in a lower temperature environment for chemical reactions.
- 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:What is the chemical nature of the enzyme?
- Enzyme protein and cofactor are present in the absence of catalytic activity, only these two parts together to form a complex to show the catalytic activity of this complex called the whole enzyme. Some enzymes cofactor is the metal ion, some enzyme cofactor is Organic small molecules in these organic small molecules, where the enzyme and protein binding is called the auxiliary base; and with the enzyme protein binding was more relaxed, dialysis can be used to separate the enzyme protein is called coenzyme. There is no strict boundary between the base and the coenzyme, the role of the metal ion in the enzyme molecule, or as a component of the active site of the enzyme, or the conformation necessary to form the center of the enzyme, or between the enzyme and the substrate The same coenzyme is often able to bind to a variety of different enzyme proteins, the composition of a variety of catalytic functions of different enzymes, such as coenzyme Ⅰ (NAD +) can be a variety of enzymes, As a coenzyme for many dehydrogenases, but each enzyme protein can only bind to a specific coenzyme into a whole enzyme.It can be seen that the specificity of the enzyme is the enzyme protein part of the coenzyme in the enzymatic reaction is usually responsible for electrons, atoms Or some chemical groups to determine the nature of the reaction.In recent years, it has been found that, in addition to proteins, some RNA and DNA molecules also have a catalytic effect on the chemical nature of the enzyme is the concept of protein produced a strong impact . However, the now known enzymes are essentially protein-based, or protein-dominated core components, and the concept that the enzyme is a protein-based biocatalyst does not exclude the presence of other types of catalysts, and more precisely, Can be given to the enzyme under the definition of: the enzyme is a kind of biological activity and special space conformation of biological macromolecules, including protein and nucleic acid.
