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 is the principle of the catalyst?
If you are not asking for a written, you can look at my words. The principle of the catalyst is to make the water muddy. It has to accelerate the chemical reaction, but also slow down the reaction. Catalyst ions into the solution, is to let the solution become muddy, and then should be the reaction of the ion collision probability is large, to speed up the reaction. The substance of the catalyst does not participate in the reaction, so it does not change. Are personal understanding, wrong please more inclusive. Thank you
Q:catalyst efficiency low bank 1?
The question was for bank 1 and the code is for bank2.Toadyboy is correct.Follow his lead.
Q:Explanation of Catalysts?
Hi Ganah! A catalyst is a substance that increases the rate of a chemical reaction without itself being used up in the reaction. They lower the activation energy for a reaction and also speed up the rate of the reaction (both in reverse and forward reactions). Let's look at a generic chemical reaction: A + B---C + D C + D---B + E Here, the catalyst is substance B because it is part of the chemical reaction but then it is not used up in the net reaction. See how it seems to be used up in the first step, but by the second step, the catalyst is made once again. The net reaction is A + B--->B + E and you can see how it is not consumed in the reaction. There are also 3 types of catalysts. Heterogeneous catalysts are catalysts that are in different phases than the reactants. An example would be like a reaction between two solids but a liquid is added to speed up the reaction. The liquid is in a different state of matter than the solids but it can still function as a heterogeneous catalyst. Homogeneous catalysts are catalysts that are in the same states of matter as the reactants. An example would then be ethyl acetate reacting with water to form acetic acid and ethanol with an acidic catalyst. They would all be liquids. Lastly, there are enzyme catalysts. These are proteins in your body that speed up biological reactions by reacting with substrates. I hope this helped and good luck with chem!
Q:How does active charcoal catalyze in some chemical reactions?
Activated carbon is generally in the catalytic reaction to do more carriers, has not yet seen its catalyst to report.
Q:Catalyst and Intermediate.?
Cl is the catalyst. ClO the intermediate. The catalyst is the component which does not change in overall reaction. He forms some intermediate component(s) with the reactants. In the later reaction steps the intermediate(s) react forming the catalyst in its original state. (a) The overall order is the sum of the orders with respect to the components: n = 1 +1 = 2 (b) the unit of the rate of reaction is r [=] mol/ (Ls) (more general mol per unit time and volume) compare dimensions mol / (Ls) [=] k · mo/L · mol/L =k [=] L/(s mol) (more general unit volume per unit time and mole) (c) First reaction For elementary reaction steps the order of the reaction rate with respect to a reactant is equal to stoichiometric coefficient. Hence the rate of first reaction is: r₁ = k₁·[Cl]·[O₃] Overall rate is given by the rate determining step, while other reaction steps are in equilibrium: r = r₁ = k₁·[Cl]·[O₃] If second reaction is the rate determine step r₂ = k₂·[O]·[ClO] while reaction 1 is at equilibrium K₁ = ( [ClO]·[O₂] ) / ( [Cl]·[O₃] ) =[ClO] = K₁·( [Cl]·[O₃] ) / [O₂] the overall rate would be: r = r₂ = k₂·[O]·[ClO] = K₁·k₂·[O]·[Cl]·[O₃] / [O₂] = k·[O]·[Cl]·[O₃] / [O₂] That doesn't match the observed rate law
Q:Can some chemical reactions have a variety of catalysts that are correct or wrong?
Very correct, many reactions can have a lot of catalyst. Such as hydrogen peroxide decomposition can be used manganese dioxide or fe destroy
Q:What is the maximum impact of the chemical reaction rate?
But the temperature is greater than the concentration of concentration and pressure on the solid and pure liquid is not affected
Q:Biological enzymes and chemical catalysts of the differences in the source
Biological enzyme catalytic reaction conditions are mild, high selectivity, can not be infected
Q:How the catalyst accelerates the chemical reaction
The catalyst is the catalyst that accelerates the chemical reaction by accelerating the chemical reaction
Q:In the chemical calculation, the quality of the catalyst should not be counted before and after the reaction
It is not the same .. because the quality of the catalyst will not change .
