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: Is the catalyst considered a chemical reaction?
- The catalyst is involved in the reaction, but in the reaction process is a step in the effect of its shape has not changed, so that did not participate in the reaction.The role of the catalyst is to reduce the activation energy of the reaction, the original one reaction into two or Multiple reactions, each sub-reaction of the activation energy is very low, the reaction is very good, the effect is the total reaction faster. Hope to adopt
- Q: Chemical Reactions Under what circumstances the catalyst accelerates the reaction
- First, more than ninety-nine percent of the catalyst is accelerating the reaction, and if the catalyst kinetics reduces the energy barrier of the reaction, the reaction will naturally accelerate.
- Q: Why is the catalyst in the chemical balance, the rate of change and balance?
- Plus the catalyst, but only to change the activation energy of the reaction, so that more molecules at the same time to participate in the reaction.
- Q: Why are catalysts so effective in small amounts?
- By definition, catalysts serve to accelerate certain chemical reactions, by lowering the activation energy required for them to proceed. They are not consumed by the reaction, which is why they are effective in small amounts.
- Q: Will the catalyst in the chemical reaction be reduced?
- The amount of catalyst in the chemical reaction is not reduced, the catalyst is divided into a positive catalyst and a negative catalyst, the positive catalyst promotes the reaction, and the negative catalyst inhibits the reaction
- Q: It's a GCSE Chemistry questionI just need to know why there are so many
- Many important chemical reactions require inputs of energy to proceed. If a catalyst is present less energy will be required to complete the reaction. Catalysts are substances that are mixed in with materials that are to be reacted, but they themselves do not, in the end, change chemically. They establish a local environment that promotes one or more chemical reactions to take place. A catalyst is important in many industrial processes. Sulfuric acid, which is used to produce batteries, detergents, dyes, explosives, plastics, and many other produces, is commonly produced using a catalyst called vanadium oxide. Ammonia, a primary component of many fertilizers, could not be produced economically without the use of iron oxide which speed up the reaction. The process of catalyst also affects the state of our global environment. Automobiles use catalytic converters to treat exhaust. The metals platinum and palladium facilitate the chemical conversion of noxious gases to more inert forms, greatly decreasing the environmental impact of combustion engines. Probably the most important impact of catalyst is on life itself. All important biochemical reactions are catalyzed by molecules called enzymes. Most enzymes are proteins which catalyze specific reactions within cells. Some examples include polymerases, which synthesize DNS and RNA, peptidases, which digest protein, and ATP synthases, which produce energy for the many different cell activities.
- Q: A substance involved in chemical reflection, but reflects the quality of the material before and after the change, you say it is a catalyst?
- The role of the catalyst is to change the reaction rate of the chemical reaction, which itself does not participate in the reaction! The
- Q: Explain how catalysts help to reduce costs in industrial processes !?Thanks
- they reduce the activation energy of a specific chemical reaction, which in turn reduces the temperature at which a reaction will occur at any significant rate (and therefore fuel costs) while generally making the reaction occur faster. In general, if you can catalyze a reaction, you can get away with using less robust equipment because you don't need as much energy.
- Q: Chemical reactions in the presence of impurities will cause catalyst poisoning, how to understand this sentence
- This is in the chemical balance, but also alone
- Q: woulld you be able to answer these aswell i really dont know how to do this cehmestryExplain how, and why, an atom of chlorine (Cl) and an atom of lithium (Li) would form a chemical bond with each other. (iii)Explain what is meant by electronegativity and how it can be used to determine the nature of a chemical bond. (iv)Write a note outlining what is meant by vapor pressure and explain how the concept is used to define the boiling point of a liquid.
- Because of the production of photochemical oxidants from NOx reacting with hydrocarbons in sunlight Noxer blocks are used to rid the NOx from the surroundings through The titanium dioxide (TiO2) on the bocks absorbs ultra-pink radiation from daylight which excites its electrons to a bigger orbital. On the outside of the crystals of TiO2 a reaction happens between oxygen and a high power electron from the TiO2. O2 + e? --O2 ? The excessive vigor electron is then given back to the TiO2 when water then reacts with the oxygen to present H2 O + O2 --H+ + O2 ? + OH Nitrogen dioxide is oxidised to nitrate ions as a result of the hydroxyl radical being an awfully strong oxidising agent NO2 + OH --H+ + NO3 ? The superoxide from response 3 also varieties nitrate ions from nitrogen monoxide. NO + O2 ? --NO3 ? This nitrate is washed away through rain or combines with the concrete within the block.
