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: Does the catalyst participate in chemical reactions?
- The catalyst does not participate in the chemical reaction, it only plays an auxiliary role.
- Q: Are biological enzymes harmful to humans?
- Biological enzymes through scientists more than a century of research, usually known as more than 3,000 kinds of enzymes, the current application of biological enzymes in the textile a wide range of technology, fiber modification, silk degumming, raw hemp (ramie, linen, Kenaf) degumming, dyeing and finishing of the desizing, refining, finishing and net cleaning processing, textile printing and dyeing wastewater treatment and garment processing and other aspects of the application. Enzyme technology has a unique advantage in improving dyeing and finishing processes, saving energy, reducing environmental pollution, improving product quality, adding value and developing new raw materials. At present in the textile processing using a wider range of enzyme system
- Q: Always speeds the reation ratedoes not affect the reation rateundergoes a chemical changedoes not become part of the chemical changealways slows the reation rate
- The best answer is speeds the reaction rate. Generally it lowers the activation energy so that the reaction can proceed easier. Enzymes can be considered catalysts in the body that allow digestion to occur at a temperature like body temp, where it would go faster at a higher temp.
- Q: Does a catalyst work for both reactants and products?From my understanding, organic catalyst or enzyme does not necessarily work for the product of the reaction because of the shape of the activation site. However I cannot speak for inorganic ones.
- Generally, catalysts participate and facilitate a reaction, but the catalyst is returned unchanged. For example, sulfuric acid may be used in a Fischer esterification, palladium in a Heck reaction, pyridine in an acylation reaction, hydroxide in an aldol condensation, cyanide in a benzoin condensation, etc. An enzyme can facilitate a reaction is a similar manner, by being an acid or base catalyst for example. We could say that generally, reactions are reversible. Practically, that is not true as the energy differences of the reactants and products may be so different to prevent the reverse, an explosion for example. If a reaction is reversible, that may not mean the reverse reaction will take place. Le Chatelier's Principle can apply to determine the products.
- Q: in acid-catalyzed reaction,there are some books show the acid catalyst as H+ and there are some show it as H3O+ .Are they the same?
- Short=yes they are. Long version Traditionally, acids were defined to be compounds that produce H+ ions when dissoved in water (Arrhenius theory). But this definition is limited to acids that can be dissolved in water. Br?nsted-Lowry then formed a definition which states that acids are compounds which donates a protons or H+ ions. If u think about it, a H+ ion is practically a proton. a proton with no electron outer shell is far too reactive to stay in its current state. thus it will form a bond with H2O to form H3O+ Because of this, acid catalysts are supose to be H3O+ instead of H+. But since it is more convinient to use H+, the form of writing H+ remained instead....... and yes...... the scientists were lazy......
- Q: I think doubling the concentration of catalyst will double the rate of a reaction (K2/K1 =2). I want to confirm. This is for my project work. Please reply as soon as possible.
- A catalyst speeds up a chemical reaction by providing an alternate reaction pathway with a lower activation energy, thus increasing the number of collisions that can result in the formation of product. When the catalyst is a reactant in the rate determining step, and the reaction is first order in the catalyst, then a doubling of the concentration will double the rate. But if the rate determining step which includes the catalyst is not first order, then doubling the concentration won't double the rate. Then there is the case of a heterogeneous catalyst in which the reaction is essentially zero order in the catalyst. The amount of catalyst won't affect the speed of the reaction beyond the initial increase. The mere fact that the catalyst is present speeds up the reaction.
- Q: What kind of chemical substances can seriously damage the ozone layer, as a catalyst or reactants can be?
- Hundreds of years ago the news once the industrial production and emissions of ozone generated less way, the ozone layer will still be thin.
- Q: give an example of how a catalysts speeds up the rate of reaction?? thank you!!?
- Catalysts speed up a reaction, but at the end of it, it's chemically unchanged. You usually have the same mass at the end of the reaction. For example.. Consider the decomposition of Hydrogen Peroxide: 2H2O2 -2H2O + O2 I hope you got how to represent it =D So.. This reaction is very slow. You can try it out in the lab. So when we add a catalyst, the reaction speeds up. The catalyst used here is MnO2.. Manganese dioxide. Well.. The Enzymes in our body are also Catalysts. They speed up the Biological Reactions taking place inside out body. I hope this answers your question. :) Cheers
- Q: What are the catalysts?
- The relationship between it and the reaction system is as highly selective (or specific) as the relationship with the key. A catalyst does not catalyze all chemical reactions, such as manganese dioxide in the decomposition of potassium chlorate Play a catalytic role to speed up the chemical reaction rate, but the other chemical reactions do not necessarily have a catalytic effect
- Q: What is the catalyst called?
- Junior high school book definition: in the chemical reaction can change the chemical reaction rate of other substances, and its own quality and chemical properties before and after the reaction did not change the material called catalyst, also known as catalyst. The role of the catalyst in the chemical reaction is called catalysis.
