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:What progress has chemistry brought to our life?
Q:On the issue of chemical balance and catalyst
If the chemical equilibrium does not move, then only the catalyst can change the time to reach equilibrium. If you change the temperature, pressure, it will affect the chemical balance.
Q:Chemical "catalyst can speed up the chemical reaction rate of other substances," this sentence right?
Wrong, the catalyst is divided into two kinds, one is to speed up the chemical reaction speed, and the other is the opposite
Q:What is a catalyst/catalase? help?
Catalysts and catalase are two different things, and the definitions that you listed are correct. A catalyst is something that speeds up the rate of a chemical reaction. Many chemical reactions occur naturally and do not require any energy, but they occur so slowly that they are not useful, and catalysts can be used in cases like this to speed up the process. For example iron metal exposed to oxygen and water turns to rust, but if you need a lot of rust by tomorrow, leaving a chunk of iron out in the rain is not a practical solution because it will take too long to convert all that iron metal into rust.
Q:can you guys help me by listing all the catalysts?
copper nickel zinc common catalysts are solid acids such as the silicas, alumina, and zeolites it depends on the reaction
Q:How does oxygen sensor affect catalyst converter?
The oxygen sensor senses whether the exhaust coming out of the engine is clean of emissions gasses. It can also alter the air-fuel mixture in the engine to run leaner or richer. And yes, it's always a good idea to change the oxygen sensor when changing the c.c. because it can damage the c.c or other components in your engine.
Q:Why are transition metals more likely to be catalysts?
transition okorder.com/... for ex-- X (one reactant) + catalyst(transition element) ------X.catalyst(intermediate unstable compound) X.catalyst + Y (other reactant) --------XY(product) + catalyst how the change in oxidation state of transition elements helps the reacton through the formation of intermediates may be seen from reaction in between SO2 and O2 to form SO3 in presence of V2O5 ... V2O5 + SO2 ------V2O4 + SO3 2V2O4 + O2 ------2V2O5 in the above reaction vanadium changes its oxidation state from +5 to +4 and again to +5.. another example is reaction in between iodide and persulphate ions in presence of Fe(III) as catalyst... 2I(-) + S2O8(2-) ---------I2 + 2SO4(2-) (Fe(III) is present as catalyst) the reaction is believed to take place as follows: 2Fe(3+) + 2I(-) ------2Fe(2+) + I2 2Fe(2+) + S2O8(2-) ------2Fe(3+) + 2SO4(2-) (3)in number of cases transition elements provide a suitable large surface area with free valencies on which reactants are absorbed ...as a result concentration of reactants on surface of catalysts increases..hence rate of reaction increases...this is known as adsorption theory.... according to adsorption theory : there are free valencies on surface of solid transition metals because of the incomplete d-subshelll.. so the mechanism of catalysis involve followin five steps: (1) diffusion of reactant molecules towards surface of catalyst... (2) adsorption of reactant molecules on surface of catalyst by forming loose bonds with catalyst due to free valencies... (3)occurence of chemical reactions between reactant and catalyst forming an intermediate.. (4)desorption of product molecules from surface due to its lack of affinity for the catalyst surface thereby making the surface free for fresh adsorption of reactant molecules... (5)diffusion of product molecules away from surface of catalyst...
Q:Copper oxide and ferric oxide can replace manganese dioxide as a catalyst in chemical reaction?
Can not. They will react
Q: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:In the chemical reaction, why can the catalyst speed up the reaction rate
Iron catalyzes nitrogen and hydrogen synthesis of ammonia, and no iron reaction occurs almost.
