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:put in a way that a freshman in high school can understand please =)
- enzymes are biological catalysts catalysts and enzymes speed up a reaction without being used up
- Q:Explain how catalysts help to reduce costs in industrial processes !?Thanks
- They speed up a reaction, allowing you to get more product more quickly and remain unchanged, therefore you can use them over and over again.
- Q:I know that a species that does not appear in the chemical equation may also affect the rate of a reaction - e.g. a catalyst. But does that mean the catalyst can be present in the rate equation, and if so are catalysts always present in the rate equation?
- All the factors that affect a reaction rate, except for concentration and reaction order, are taken into account in the rate equation of the reaction. A catalyst: The presence of a catalyst increases the reaction rate (in both the forward and reverse reactions) by providing an alternative pathway with a lower activation energy. en.wikipedia.org/wiki/Reaction_ra...
- Q:A catalyst elevates the rate of a reaction by?
- Catalysts work by providing an (alternative) mechanism involving a different transition state and lower activation energy. Consequently, more molecular collisions have the energy needed to reach the transition state. Hence, catalysts can enable reactions that would otherwise be blocked or slowed by a kinetic barrier. The catalyst may increase reaction rate or selectivity, or enable the reaction at lower temperatures. This effect can be illustrated with a Boltzmann distribution and energy profile diagram. Take a look!
- Q:Also, how is the catalyst affected by heat? Please answer all of the questions not just one of the three. THANK YOU!
- The catalyst is affected by vinegar because vinegar is acidic meaning there are more H+ ions. This alters the charges on the R groups of the amino acid residues of the enzyme molecule. The bonds that help maintain the conformation of the enzyme molecule which is ionic will therefore, be disrupted and the binding of substrate will be affected. However, if pH is restored to optimum pH, the maximum activity of the enzyme will be restored but this is only if the pH was only altered by a small extent. If pH is altered by a large extent, the conformation of the enzyme molecule will be severely affected causing it to denature. The catalyst is affected by heat because excessive heat disrupts the intermolecular bonds which stabilise the secondary and tertiary structure of an enzyme molecule(the enzyme molecule has a tertiary structure). The enzyme molecule unfolds and the precise shape of the active site is lost. This loss of structure and function is irreversible.
- Q:How the catalyst accelerates the chemical reaction
- The catalyst is the catalyst that accelerates the chemical reaction by accelerating the chemical reaction
- Q:Chemical catalyst in several ways
- In general, positive catalyst (accelerated rate) and negative catalyst (slowing down)
- Q:how a catalyst can provide a new route in forming the product?
- catalyst speeds up the reaction... i don't know if there is actually 'a new route' in product formation because catalysts should not affect the reaction... it only has to speed up the reaction
- Q:Carbon dioxide and hydrogen in the catalyst and heating conditions, the reaction of water and methane, the chemical equation is what
- CO2 + 4H2 = catalyst, heating = 2H2O + CH4
- Q:in my 99 ram 2500 v8 5.9 that code came up, not sure what to do about it or what it could be any ideas or help with be great thanks
- This Site Might Help You. RE: catalyst efficiency low bank 1? in my 99 ram 2500 v8 5.9 that code came up, not sure what to do about it or what it could be any ideas or help with be great thanks
