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 are the catalysts that appear in the chemistry experiment?
- Oxygen Oxygen Oxygen Oxygen also used when the catalyst is manganese dioxide MnO2
- Q:the heterogenous catalyst ZSM-5 IS used to convert ?
- Zeolite-based heterogeneous catalysts are used by industrial chemical companies in the interconversion of hydrocarbons and the alkylation of aromatic compounds. A very good example is the zeolite ZSM-5. This zeolite, developed by Mobil Oil, is an aluminosilicate zeolite with a high silica and low alumininum content. Its structure is based on channels with insecting tunnels. The aluminium sites are very acidic. The substitution of Al3+in place of the tetrahedral Si4+ silca requires the presence of an added postive charge. When this is H+, the acidity of the zeolite is very high. The reaction and catalysis chemistry of the ZSM-5 is due to this acidity. The ZSM-5 zeolite catalyst is used in the petroleum industry for hydrocarbon interconversion. An example use is in the isomerizations of xylene- from meta to para-xylene. The acidic zeolite promotes carbocation isomerizations. There are two suggested mechanisms for this type of isomerizations. Firstly shape may play a role. Perhaps para-xylene has a shape which allows it to diffuse rapidly through the zeolite structure, whereas as meta-xylene takes longer to pass through the zeolite and thus has more opportunity to be converted into the para-xylene. Secondly, is that the orientation of reactive intermediates within the zeolite channels favors specifically para-xylene.
- Q:Where are they good catalysts and why?? THanks!
- A catalyst is a substance that speeds up a chemical reaction by providing an alternate reaction pathway with a lower activation energy. Catalysts appear not to take part in the reaction. Frequently, catalysts are not very reactive. Acids and bases, on the other hand, are very reactive. Acids (as H+) and bases ( as OH-) sometimes function as catalysts in some organic reactions. They appear to be catalysts because in the course of the mechanism H+ or OH- is regenerated.
- Q:What is the reaction of hydrogen peroxide to add manganese dioxide?
- This problem is not easy to answer, the principle of manganese dioxide catalytic hydrogen peroxide I have not learned, but I have also considered, I think so, hydrogen peroxide and manganese dioxide first combination, the formation of permanganic acid, permanganic acid is a Very special acid is indeed present, it can not be stable under normal conditions, it will be further decomposition, the formation of manganese dioxide, oxygen and water
- 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: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:Nitrogen and hydrogen in the role of high temperature and pressure catalyst to generate ammonia chemical equation
- N2 + 3H2 = catalyst, high temperature and high pressure = 2NH3
- Q:okay im doing a project for my classroom about catalyst and i have to draw a picture but when i looked up on google i just saw a bunch of random stuff and a couple were metal so thats why im asking this question. :)

- Q:Can a catalyst react with a reactant?
- Catalysts are of different categories. There are some reactions, in which only the presence of some compound increases/decreases the rate of the reaction. In other examples, the catalyst do react with the reactants and provide a different path for the reaction. The product is formed and the catalyst is recovered. Not even a single molecule is consumed after the reaction. But if you take a sample while the reaction is going on, you might find a decrease in the concentration of the catalyst. (An example is the use of Mangnese dioxide (MnO2) in the conversion of Potassium Chlorate (KClO3) to Potassium Chloride and oxygen. The MnO2 added at the initiation of the reaction is in form of crystals and at the end of the reaction it is recovered as finely divided powder. This simply shows that MnO2 reacted with KClO3 initially and finally got detached in form of a powder.)
- Q:Characteristics and types of catalysts?
- Catalysts don't undergo any change. and types of catalysts - 1) Homogeneous Catalysts ( Having same phase that of reactant, product i.e. reactant and product and catalysts all are either liquid or gas or solid.). 2) Hetrogenrous Catalysts (Different Phase than that of reactant and product. 3) Autocatalysts (reaction proceed catalysed as product is formed or product catalyse the reaction.)
