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: The "one-to-two change" of the catalyst is that the quality and chemical properties of the reactants are constant or the quality and chemical properties of the catalyst are constant?
- The change in chemical reaction rate is the same as the chemical nature and quality
- Q: Is the catalyst in the field of inorganic chemistry?
- In the chemical discipline, including inorganic chemistry, analytical chemistry, organic chemistry and physical chemistry and other secondary disciplines, catalytic science for the three disciplines, generally attributed to the physical chemistry of the mouth.
- Q: And hydrogen peroxide
- No
- Q: what is a catalyst ?
- OK- First about what a catalyst does. All reactions require some amount of energy to proceed. For most of of these it is not much and it comes from the reactions immediate environment and we don't notice it. This energy needed is called an energy threshold. Many, if not all, reactions can have their thresholds lowered by something else-platinum-nickle in the cars catalytic converter does this. Catalysts are not used in the reaction so the catalyst, once added, stays there and continues working. By the way, in biology we have organic catalysts (the enzymes).
- Q: What is the nature of the chemical catalyst?
- Catalyst is the chemical reaction can change the reaction rate of other substances, and its own quality and chemical properties in the chemical reaction before and after the material has not changed Some catalyst can really slow down the reaction rate, the book said only refers to the usual circumstances , In general, junior high school and high school teaching into the do not do special instructions are understood to speed up the reaction rate. It is only necessary to know that the catalyst is not only used to speed up the reaction rate. Once the reversible reaction reaches equilibrium, adding the catalyst does not break the balance, but at the same time accelerates the forward and reverse reaction rates. The degree of acceleration is the same.
- Q: and what type of macromolecule are they made of? thanks!
- A catalyst is any substance that speeds up a chemical reaction without otherwise changing the outcome of the reaction. Catalysts do this by lowering a reaction's activation energy (which is the energy barrier that must be overcome before the reaction can proceed spontaneously). Catalysts are not permanently changed by the reactions they catalyze, so one catalyst could reasonably catalyze the same reaction many times over. Enzymes are biological catalysts because they lower the activation energy of metabolic reactions (and therefore increase their rate). Every enzyme has an active site that is specific for a particular substrate, or for a small related group of substrates. When the correct substrate binds to the active site, the enzyme catalyzes a particular reaction and releases new products. Substrates that don't match the shape of the enzyme's active site usually won't be affected by the enzyme. Enzymes are proteins, which are in turn polymers of amino acids. The sequence of amino acids in an enzyme, as well as the three-dimensional structure of the polypeptide chain, are essential for determining the enzyme's functionality. I hope that helps. Good luck!
- 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: What is the standard for the storage of flammable and explosive chemicals now?
- First, the basic requirements of classification of storage Dangerous goods, variety, complex performance, storage, in accordance with the zoning, classification, sub-section of the principle of special storage, set the number, set the number of fixed warehouses, fixed staff (four) custody. Small warehouses should be classified, divided, sub-stack storage, the performance of each other, fire fighting different items, dangerous dangerous goods and other general dangerous goods, should be stored separately.
- Q: What is the relationship between the catalyst and the chemical reaction? What is the relationship between the enzyme and the catalyst?
- Enzymes are a kind of catalyst.
- Q: How to poison the catalyst. What can be done?
- In the reactants or catalyst mixed with a small amount of material, so that the catalyst catalytic capacity of a sharp decline or even loss, this phenomenon is called catalyst poisoning. For example, in the synthesis of ammonia feed gas containing CO, CO2 and H2S, PH3, water vapor and other impurities, can make iron catalyst poisoning; contact with the system of sulfuric acid, if arsenic and selenium oxide (As2O3, SeO2), can make vanadium catalyst Loss of activity. Therefore, it is necessary to purify the feed gas, prevent the poisoning of the catalyst, and also reduce the corrosion of the equipment. The phenomenon of catalyst poisoning is sometimes temporary, the removal of toxicants, the effectiveness of the catalyst can still be restored; sometimes it is permanent, without chemical treatment can not restore catalytic performance.
