Product Description:


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 metallocene catalyst technology?
Metallocene catalyst A transition-metal atom sandwiched between ring structures having a well-defined single catalytic site and well-understood molecular structure used to produce uniform polyolefins with unique structures and physical properties. See also Catalysis; Coordination chemistry; Coordination complexes; Metallocenes; Organometallic compound. In the early 1980s, W. Kaminsky discovered that an appropriate co-catalyst activated metallocene compounds of group 4 metals, that is, titanium, zirconium, and hafnium, for alpha-olefin polymerization, attracting industrial interest. This observation led to the synthesis of a great number of metallocene compounds for the production of polymers already made industrially, such as polyethylene and polypropylene, and new materials. Polymers produced with metallocene catalysts represent a small fraction of the entire polyolefin market, but experts agree that such a fraction will increase rapidly in the future. See also Polymer; Polymerization; Polyolefin resins.
Q:What is the catalyst called?
Catalysts induce chemical reactions to change, cause chemical reactions to become faster or slower, or to react chemically at lower temperatures. The catalyst is also known as a catalyst in industry.
Q:Question about catalysts?
A catalyst works for either the reactants or the product in a given reaction. If it works for the reactants then the activation site on the enzyme, for example, will only fit on the reactants. If a catalyst is added to a reaction in which it catalyzes the back-reaction, or it aids the products, then the reaction will be reversed. i don't think a catalyst could work for both the reactants and products in one reaction because it wouldn't really be a catalyst anymore; it wouldn't make the rxn progress any faster since it would be canceling out itself by aiding both the reactants and the products. I think this is what you are asking, if not please post more details. I hope I didn't confuse you even more!
Q:No one knows the expression of the catalyst and the chemical expression of the acridine
In organic reactions, the catalyst is complex and consists of several or more. Write Chinese characters directly.
Q:What kind of chemical reaction requires a catalyst?
For example, the system of ammonia, S02 oxidation into SO3
Q:Which branch of chemistry or what specialty can study the catalyst
Analytical Chemistry: Application of Catalysts in Analytical Chemistry, Component Analysis of Certain Natural and Synthetic Catalysts
Q:enzymes and catalyst are....?
A catalyst is a substance that affects the rate of a reaction. It may participate, but cannot be consumed in the reaction. For example, KMnO4 catalyzes the breakdown of H2O2 into H2O and O2. In the end, as much KMnO4 exists as did in the beginning. An enzyme is a biochemical reagent that allows an organism to convert a compound into other compounds. This is part of metabolic processes. For example, maltose (a sugar composed of a chain of two glucose molecules) can be broken down into glucose by the maltase enzyme. Unlike a catalyst, enzymes may or may not be consumed/altered in the metabolic processes.
Q:Why are enzymes classified as organic catalysts?
Enzymes Are Classified As
Q:Chemistry why the catalyst can be equal to speed up the positive reaction rate
Since the catalyst only changes the activation energy and the amount of reactivity can be reduced, the amount of reaction energy is also reduced. Therefore, a positive catalyst is also a good catalyst for its reaction. Speed up the same multiple.
Q:Does the catalyst participate in chemical reactions?
The catalyst does not participate in the chemical reaction, it only plays an auxiliary role.
