Product Description:

Product performance:

     Polyol Benzoate (DEDB) is colorless or pale yellow transparent oily liquid, water-insoluble, soluble in aromatic hydrocarbons, ketones and ethers, and has good compatibility withpolyvinyl chloride, ethylene - vinyl acetate copolymer, poly vinyl acetate, polymethylmethacrylate, polyvinylbutyral, nitrocellulose, and ethyl cellulose, etc.

Product application:

       Polyol Benzoate(DEDB) is an environmentally friendly plasticizer with the characteristics of strong solubility, good compatibility, low volatility,resistant to oil, water, light, pollution etc. It is suitable for processing PVC flooring material, plastisol, artificial leather, cable material, soft and hard pipe, shoes material, rubber strips, synthetic rubber, and paint, printing ink, etc. It has a better plasticized effect if it is used together withDOP or DBP, and has greatly achieved the purpose of reducing cost .

Q:All high school chemistry uses sulfuric acid as a catalyst for the reaction
Esterification reaction (dehydration), nitration (dehydration, concentrated nitric acid), carbonation reaction or dehydration reaction (organic matter in sulfuric acid blackening, dehydrating agent), sulfonation reaction (dehydrating agent), ethylene (dehydrating agent).
Q:A catalyst elevates the rate of a reaction by?
Catalysts work by providing an (alternative) mechanism involving a different transition state and lower activation energy. Consequently, more molecular collisions have the energy needed to reach the transition state. Hence, catalysts can enable reactions that would otherwise be blocked or slowed by a kinetic barrier. The catalyst may increase reaction rate or selectivity, or enable the reaction at lower temperatures. This effect can be illustrated with a Boltzmann distribution and energy profile diagram. Take a look!
Q:The concept of catalyst in high school chemistry
The catalyst is selective, that is, a catalyst that catalyzes only one or more chemical reactions and does not catalyze all chemical reactions. However, a chemical reaction of the catalyst may be a variety of, such as hydrogen peroxide to produce oxygen in the reaction, in addition to the use of manganese dioxide as a catalyst, you can also use copper oxide, iron oxide as a catalyst. Building on the use of cement, red brick powder also catalyze the decomposition of hydrogen peroxide.
Q:What reactions need catalysts?
Reactions that have high Activation Energy need catalysts to speed up reactions. These reactions aren't spontaneous since the reactants do not have enough energy to overcome the activation energy barrier. Catalysts are compounds that speed up reactions by providing an alternative pathway for the reaction. It is a common misconception that catalysts lower the activation energy. It doesn't actually lower the activation energy, instead it provides an alternative pathway with lower activation energy. For example, breakdown of hydrogen peroxide happens in nature but, relatively slowly. When you add a little bit of manganese dioxide, the breakdown happens a lot faster. Another example is, breakdown of glucose in the body. It is facilitated by an enzyme called amylase (or carbohydrase). An industrial example is the use of vanadium pentoxide (V2O5) in the Contact process, where SO2 is converted to SO3 in the presence of V2O5. Hope that helps!
Q:catalyst question?
The purpose of a catalyst is to provide an alternate pathway for a reaction to proceed, often one with a lower activation energy, such that the reaction will generally proceed faster. The key to catalysts if they they are NOT consumed by the reaction in the end (they may be consumed in an intermediary step, but if so, a subsequent step will recreate the catalyst). In other words, catalysts do not actually participate in the reaction, so they may be reused when the reaction has completed.
Q:What kind of chemical reaction requires a catalyst?
For example, the system of ammonia, S02 oxidation into SO3
Q:What is the difference between biological and chemical catalysts?
Biological catalysis involves an enzyme usually working in conjunction with a co-enzyme. These enzyme/co-enzyme systems are highly specific and are usually only effective for one reaction. Catalysis of non biological reactions is usually much more general and any one catalyst will be effective in many reactions.
Q:Hydrogen and oxygen in the role of the catalyst can do the chemical formula of aviation fuel?
You two yeah? Meaning that hydrogen is ignited in oxygen to release energy to push the rocket forward, as the catalyst for those who love,
Q:Does the catalyst participate in chemical reactions?
The catalyst does not participate in the chemical reaction, it only plays an auxiliary role.
Q:What are the properties of the catalyst (eg, specificity)?
The composition, chemical properties and quality of the catalyst itself do not change before and after the reaction; its relationship with the reaction system is as highly selective (or specific) as the relationship between the lock and the key. A catalyst is not for all Chemical reactions are catalyzed, for example, manganese dioxide in the thermal decomposition of potassium chlorate in the catalytic role to speed up the chemical reaction rate, but other chemical reactions do not necessarily have a catalytic effect.Some chemical reaction is not only a single catalyst, such as potassium chlorate Thermal decomposition can play a catalytic role in the magnesium oxide, iron oxide and copper oxide and so on.
