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:Brief introduction of enzyme as biocatalyst and general chemical catalyst and its personality
enzyme inactivation (4) enzyme activity can be timely and effective regulation (5) the role of the enzyme conditions are more moderate (6) most of the enzyme (1) the catalytic efficiency is very high (2) Of the catalytic activity is often associated with coenzymes, auxiliary or metal ions, and some enzyme activity also need RNA as a cofactor Caixing, such as telomerase
Q:Chemistry GCSE what is a catalyst?
A catalyst is something that makes a chemical reaction happen faster. An example is when manganese oxide (MnO2) is added to hydrogen peroxide (H2O2), and the hydrogen peroxide starts to break up into water and oxygen. Catalysts are either of natural or synthetic origin. They are useful because they leave no residue in the solution they have sped up. A catalyst also can also be used in a reaction again and again. Catalysts work by lowering the activation energy of a reaction. This allows less energy to be used, thus speeding up the reaction. The opposite of a catalyst is an inhibitor, which slow down reactions
Q:Exemplify the use of green catalysts in green chemistry
The platinum and palladium catalyst in the exhaust pipe of the automobile can catalyze the formation of CO2 and N2 by NO and CO
Q:Can the catalyst be a reactant in chemistry?
In general, a catalyst is a substance that participates in the intermediate process of chemical reaction and selectively changes the rate of chemical reaction, and its quantity and chemical properties remain substantially constant before and after the reaction, and the catalyst is usually accelerated to Reaction as soon as possible to achieve the role of chemical balance called catalytic role.
Q:What kind of chemical reaction requires a catalyst?
For example, the system of ammonia, S02 oxidation into SO3
Q:Does increasing the amount of catalyst added to, say, a solution of Hydrogen Peroxide, make the rate of reaction go faster. Is the rate of reaction directly proportional to the amount of catalyst added to the solution? Or does the experiment go at the same rate regardless of how much catalyst there is? Thanks would really appreciate some answers. - Sarah
Catalyst do not participate in the reaction but it speeds up the reaction. If you increase the amount of catalyst from the required amount, it would somehow negates its positive response or it would result in producing another product.
Q:Who knows hydrogen and nitrogen in the high temperature, high pressure and catalyst conditions for the synthesis of ammonia chemical equation ah? Urgent! The SOS
3H2 + N2 ===== 2NH3 conditional catalyst
Q:What chemical reactions can water do the catalyst?
So far heard, but can and Na and other metal reaction
Q:how do catalysts help in green chemistry?
Catalysts reduce the energy barrier for reactions, meaning they require less energy to make the forward reaction go. This means less heat, light, or other energy sources are required to perform the same reaction without a catalyst. Also, by definition, a catalyst is not consumed in a reaction and can therefore be recycled many many times before replacement is necessary.
