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:how does the catalyst work (to speed up the reaction)??
you can say catalyst react with the reagent and it gives intermediate product, this product can easier react with another reagent (the activation energy is lower). And in the end the catalyst is reconstructed. Scientists determine the catalyst in experiments...
Q:Describe the role of a catalyst..........?
a catalyst speeds up the reaction
Q:Chemical Glossary: Catalyst
The catalyst is a substance that can change the rate of the reaction without changing the standard of the reaction Gibbs free, according to the definition of the International Pure and Applied Chemistry (IUPAC) in 1981, Enthalpy change. This effect is called catalysis. The reaction involving the catalyst is a catalytic reaction.
Q:What is the difference between biological and chemical catalysts?
catalysts which catalyze the chemical reactions taking place in human body such as enzymes are called bio-catalyst and other one's which are generally used in laboratory by chemists for multiple type of reactions are chemical ctalysts
Q:Does the catalyst affect the chemical reaction rate constant?
The catalyst will change the rate constant
Q:What is the chemical vinyl chloride and benzene plus catalyst?
Looks like no ethyl benzene, it is vinyl benzene
Q:Does the catalyst slow down the chemical reaction rate?
The role of the catalyst is to change the activation energy to achieve the purpose of changing the reaction rate, there is a rate of response to speed up the rate of slow response
Q:Is the enzyme in the enzyme bigger than gold?
No: A biological enzyme is a biocatalyst that is produced or extracted from a biological organism. The catalyst is a substance that accelerates the chemical reaction and does not change itself in the chemical reaction. In layman's terms, the catalyst is a special substance that catalyzes it. Enzyme as a member of the catalyst family has its own special properties. Each of the biological enzymes will only selectively react to some chemical reactions.
Q:explain how a catalyst can affect the rate of reaction but not be in the overall equation.?
Simply, the catalyst provides a better way for the reaction to occur (some won't work without the catalyst) and usually a favorable reaction will run faster if there is a catalyst. There are many ways for this to happen. The catalyst can provide more surface area for a reaction to occur, it can do an adsorption process where one of the reactants sticks to the surface and exposes a portion of the molecule which is more favorable to the reaction. It can lower the energy required for the reaction to occur (same effect as increasing temperature) by favoring an intermediate step in the reaction. Lots of different ways, some not fuly identified or understood. The catalyst people who work with the platinum metals groups are notorious for keeping their mixtures secret. A better gasoline catalyst for refineries is worth billions in profits. It is not considered in the equation because you get back what you start with even if one of the intermediate steps involves changing the chemical composition of the catalyst and then has it returning to its original state with the formation of the product.
Q:Does the catalyst participate in chemical reactions?
The catalyst does not participate in the chemical reaction, it only plays an auxiliary role.
