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: Why the catalyst after the chemical reaction of its quality and chemical properties unchanged
- The catalyst is only a catalytic role, not directly involved in the reaction, the current principle of its role is not clear
- Q: Have you Read it ? If SoCan You Think Of Any Good Group Discussion Questions ?
- yea is an extremely solid e book yet very tragic. there have been no longer any sesquipedalian words( clever and long ) and you are able to desire to get words u mite no longer understand wid counsel from contxt clues. have enjoyable!!
- Q: Who knows hydrogen and nitrogen in the high temperature, high pressure and catalyst conditions for the synthesis of ammonia chemical equation ah? Urgent! The SOS
- 3H2 + N2 ===== 2NH3
- Q: In the catalyst and light conditions to break down the water to get the chemical equation of hydrogen
- 2H2O = 2H2 ↑ + O2 ↑
- Q: What is the catalyst for ethylene addition water? How to play a catalytic role.
- With dilute sulfuric acid can be. Sulfuric acid will be added with the addition of ethyl hydrogen sulfide, and then hydrolyzed into ethanol.
- Q: I think doubling the concentration of catalyst will double the rate of a reaction (K2/K1 =2). I want to confirm. This is for my project work. Please reply as soon as possible.
- A catalyst speeds up a chemical reaction by providing an alternate reaction pathway with a lower activation energy, thus increasing the number of collisions that can result in the formation of product. When the catalyst is a reactant in the rate determining step, and the reaction is first order in the catalyst, then a doubling of the concentration will double the rate. But if the rate determining step which includes the catalyst is not first order, then doubling the concentration won't double the rate. Then there is the case of a heterogeneous catalyst in which the reaction is essentially zero order in the catalyst. The amount of catalyst won't affect the speed of the reaction beyond the initial increase. The mere fact that the catalyst is present speeds up the reaction.
- Q: What is the quality of the catalyst in the chemical reaction, for example, 34.3 g before the hydrogen peroxide reaction, 32.7 g after the reaction, and how much is the catalyst mass?
- You can not calculate this question, the quality of the catalyst before and after the same reaction, how much reaction before the reaction on how much
- 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: In biology, the enzyme seems to be a tool for opening a reaction, such as the decomposition of cellulose, such as linked RNA and protein, no enzyme can not. But in chemistry, the catalyst is only a regulatory role, change the reaction rate only. The teacher said that the enzyme is the catalyst. Is there any other effect of the enzyme? (Ignorant high three dogs, you do not spray the big god)
- But let's not say that there is no enzyme or catalyst, the reaction can not be carried out. In the process of random collision of a molecule, the occasional jump of 3 meters is also possible, but the probability is low. From the macro point of view, is the reaction rate is low. So what rate, catalyst, or what xxx let high school teacher how to say, chemical catalysis and enzyme catalysis of the fundamental principles are the same, so you go to college to understand.
- Q: What kind of compounds or elements can be used as catalysts in high school chemistry? What is the catalyst for what?
- Manganese dioxide and iron are more common, vanadium oxide sometimes encountered, sulfuric acid is also a catalyst, but generally used as a dehydrating agent. Inorganic catalysts catalyze the object is diverse, unlike the organic catalyst as a single, so hard to say. In high school is probably used to prepare oxygen when the use of manganese dioxide
