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:The role of catalyst in chemical reactions
The role of the catalyst is to change the reaction required to achieve the activation energy, can reduce the activation energy is called positive catalyst (that is, usually the meaning of the catalyst), to improve the activation energy is negative catalyst
Q:how do catalysts work?
Catalysts lower the activation energy of a given chemical reaction, thus speeding it up
Q:What is a catalyst and what is it do?
Catalyst are the substances which increase the rate of reaction. They do not get consumed in the reaction but they participate in intermediate reactions. The catalyst action can be explained as- Providing alternate energy path- Let us suppose that an endothermic reaction need 15 joules of threshold energy to occur. The catalyst will provide them path which needs less energy. Providing Surface- Many reaction may occur slowly because less contact between the molecules/atoms/ions or due to unavailability of proper structure, in this case the catalyst provide surface for carrying the reactions. There are several other actions which mayn't be necessary for you to understand the basic function of catalyst.
Q:A biological catalyst or a chemical reaction facilitator is know as a/an?
organic and organic catalyst is called ENZYME. A chemical reaction facilitator is called Catalyst A organic and organic molecule that aids enzimes paintings is called Cofactor despite if it extremely is metallic or coenzyme if its organic and organic in foundation.
Q:What is the difference between a catalyst and an inducer in a chemical reaction?
The catalyst does not participate in the reaction, but only the carrier of the reaction; the inducer will participate in the reaction
Q:Chemical problems, the selection of catalysts.
With dilute sulfuric acid can be. Sulfuric acid will be added with the addition of ethyl hydrogen sulfide, and then hydrolyzed into ethanol.
Q:why are catalysts never used up during reactons?
Catalysts facilitate the reaction. They might work in several ways. Here is an example: Catalysts generally react with one or more reactants to form intermediates that subsequently give the final reaction product, in the process regenerating the catalyst. The following is a typical reaction scheme, where C represents the catalyst, X and Y are reactants, and Z is the product of the reaction of X and Y: X + C → XC (1) Y + XC → XYC (2) XYC → CZ (3) CZ → C + Z (4) Although the catalyst is consumed by reaction 1, it is subsequently produced by reaction 4, so for the overall reaction: X + Y → Z They might also just increase the surface area, thus speeding up the reaction. Example: Coke looses its fizz over time if left with the cork unscrewed. This is because the HCO3 is released as CO2. If you drop a menthos into the coke, it explodes with CO2, because the methos is full of tiny dents in the surface (thus giving it a massive surface area). (i blatantly copied the first example from the wiki)
Q:Final Fantasy XIII: Do I need to be worried about accidently using a component that is a catalyst?
Catalysts can only be used when the item is ready to evolve. On top of that you can't use a different kind of catalyst than the one actually require and you can't use too many or too few. Catalysts are basically automatic as long as you have enough, all you can do is choose to use them. On the other hand, you CAN accidentally use sells for a premium as a material. Those items are universally horrible as a material, but sell really well in the shop. Don't use them by accident, sell them as soon as you can.
Q:Is catalyst a metal or just a hard material?
A catalyst most often is a metal in the form of a screen or sponge with lots of area although it can be an immiscible liquid or sand like particles that can be filtered out.
Q:Chemical catalyst
Catalyst reaction is essentially involved in the reaction, we learn the chemical reaction is simplified, in fact, most of the reactions are to go through several processes to form, because it is more complex, we learn to write directly reactants and products , The reaction is saved in the middle of the catalyst is involved in the middle of the reaction process, in the final process and generated, to achieve the effect of catalytic reaction, its own quality and nature has not changed.
