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: A biological catalyst or a chemical reaction facilitator is know as a/an?
- A biological catalyst is an enzyme. Here are more details for you. Enzymes – biological catalysts Normally chemical reactions do not proceed spontaneously, but require the help of a catalyst. A catalyst accelerates a chemical reaction without itself being changed. For example, the reaction of hydrogen with oxygen to produce water requires the addition of the metal platinum. These days we encounter the concept of a catalyst most often in connection with technology for cleaning up the exhaust fumes from our automobiles, where platinum and rhodium catalyze the breakdown of polluting nitrogen oxides. Chemical reactions within living cells must also be catalyzed. Biological catalysts are called enzymes. There is, for instance, an enzyme in our saliva which converts starch to a simple sugar, which is used by the cell to produce energy, and another enzyme which degrades the excess lactic acid produced when we overexert ourselves. All green plants contain enzymes which convert carbon dioxide in the air to nutritious carbohydrates such as sugar and starch. Without enzymes life would not be possible! Enzymes are highly selective. Among the thousands of different compounds in a cell, an enzyme can recognize the right molecule (substrate) and transform it into a new product. This property arises from the special three-dimensional structure of each enzyme. One can compare an enzyme and its substrate with a lock and its key. Enzymes are very effective catalysts. A chemical reaction might require several months to reach completion without a catalyst, but only a few seconds with the help of an enzyme. Since the enzyme remains unchanged, one enzyme molecule can catalyze the transformation of millions of substrate molecules. Up until the beginning of the 1980's, all enzymes were thought to be proteins. We now know that proteins do not have a monopoly on biocatalysis. RNA molecules can also function as enzymes.
- Q: What is the principle of the catalyst? Why can change the rate of chemical reactions and their own without any change
- The catalyst can be used as the reaction of the original reaction into multiple reactions, such as two, then the catalyst can be the first reaction of the product, while the second reaction of the reactants, then the overall point of view, the amount of catalyst No change, is to change the reaction process.
- 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: 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
- 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: Is it possible for the different chemical reactions to have the same catalyst?
- Right, think about the catalysis of biological enzymes
- Q: Is palladium predominantly a catalyst in chemistry?
- Palladium in the chemical mainly to do the catalyst; palladium and ruthenium, iridium, silver, gold, copper and other alloy, can improve the palladium resistivity, hardness and strength, used in the manufacture of precision resistors, jewelry and so on.
- Q: My chemistry teacher wont tell me because it's in the higher course. And i'm not waiting a whole year to find out. And also, google is being a gimp about it. So thanks a lot if you know, I only have basic chemistry knowledge btw, lumen'ss terms if you can.
- Catalysts facilitate the reaction. They might work in several ways. Here is an example: Catalysts generally react with one or more reactants to form intermediates that subsequently give the final reaction product, in the process regenerating the catalyst. The following is a typical reaction scheme, where C represents the catalyst, X and Y are reactants, and Z is the product of the reaction of X and Y: X + C → XC (1) Y + XC → XYC (2) XYC → CZ (3) CZ → C + Z (4) Although the catalyst is consumed by reaction 1, it is subsequently produced by reaction 4, so for the overall reaction: X + Y → Z They might also just increase the surface area, thus speeding up the reaction. Example: Coke looses its fizz over time if left with the cork unscrewed. This is because the HCO3 is released as CO2. If you drop a menthos into the coke, it explodes with CO2, because the methos is full of tiny dents in the surface (thus giving it a massive surface area). (i blatantly copied the first example from the wiki)
- Q: Does anybody have any tips or references I can go to for this? I'm writing a novel and the main character wants to be a catalyst; the story isn't about him and his journey, so much as the effects on everyone around him that come about simply because of him being there and being who he is. How would I go about doing this, and doing it well?
- Ways to be a catalyst: By his behaviour: - He is a good listener. People use him as a sounding board and make important decisions as a result. - He is indiscreet and inadvertently reveals people's secrets and back-sniping comments. - He is a ****-stirring gossip. - He is a home-wrecking Lothario. - He is wise and gives good advice. - He is a hooligan who ruins businesses with vandalism, costs people their jobs and ruins relationships by beating people up. - He is a manipulative, blackmailing bastard who tries to turn every woman into a prostitute and con every man out of his money. - He is a charlatan who preaches nonsense about religion, health and business investments. By effortlessly influencing other people's behaviour: - He is famous and people try to impress him wherever he goes. - He has cancer or a disabling war wound. People admire and pity him and are shocked by his PTs mood wings. - He is gay, Muslim or a suspected paedophile and people want to persecute or cure him. - He is destitute. People argue amongst themselves over whether it's because he's lazy, has bad karma or there but for the grace of God go I. - He really looks like Jesus, Buddha or Santa and the sight of him makes people contemplate their Humanist values, coming to various conclusions. Perhaps you can write about his reputation; how he earned it, how it precedes him and provokes prejudices that he sometimes confirms or disproves. Use a detached, omniscient God-narrator. (Pretend Morgan Freeman's reading the audiobook.) Alternatively perhaps he is not a catalyst but a neurotic voyeur, fascinated by the minutiae of other people's lives so that the mundane appears tumultuous. He is not influencing people but your account of the changes in people's lives are centred on his observation of them.
- Q: Chemical reaction in the presence of catalyst for the reaction are carried out a high life
- Juvenile high school you have to learn the reaction are hundreds of I can not tell you one by one you will learn some of the time can be added plus no plus can not respond
