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: When there is a catalyst in the chemical equation, it is not necessary to match the atoms of the catalyst
No, the catalyst is written above the equal sign, not the reactants, nor the product
Q: Can a catalyst decrease the rate of a chemical reaction? Please give an example if yes.
A catalyst is something that quickens the fee of reaction without getting used up itself. They many times try this by skill of lowering the activation skill, which additionally brings the optimal temperature down. So, to place it only, it relatively is B.
Q: why is palladium/platinum a good catalyst?
I'm guessing that the answer would be heterogeneous. Hydrogenation reactions use Pt and/or Pd metal as the catalyst. But these are always solids while the reaction is between H2 and either a gas or a liquid. Consequently the catalyst is in a different phase than the reactants, making them heterogeneous. I'd go with that one.
Q: Will the chemical catalyst not reduce that?
Why is it done? Although the catalyst does not react chemically, the catalyst itself is deteriorated and is not always used
Q: In the catalyst and light conditions to break down the water to get the chemical equation of hydrogen
2H2O = 2H2 ↑ + O2 ↑
Q: Does the catalyst slow down the chemical reaction rate? Still can only accelerate
The role of the catalyst is to change the activation energy to achieve the purpose of changing the reaction rate, there is a rate of response to speed up the rate of slow response
Q: What is the reaction of hydrogen peroxide to add manganese dioxide?
Hydrogen peroxide → water + oxygen (arrows on the manganese dioxide, as a catalyst)
Q: Is it possible for the different chemical reactions to have the same catalyst?
Just as manganese dioxide can catalyze the decomposition of molten potassium chlorate can catalyze the decomposition of hydrogen peroxide, but this is not necessarily the same as the catalyst for the production of the same product, but for the enzyme in order to ensure that the growth of the orderly all have a single Enzymes can only catalyze an organic matter
Q: What is the catalyst called?
There are three types of catalysts, which are homogeneous catalysts, heterogeneous catalysts and biocatalysts
