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: High chemistry: Does the catalyst affect the heat and heat of the reaction?
- No effect
- Q: Why the catalyst after the chemical reaction of its quality and chemical properties unchanged
- In fact, the catalyst reaction also enters, which changes the rate of positive and negative reactions ... enhances the reactive molecules of the reactants, thereby changing the reaction rate ...
- Q: Is it faster or slower? The What if you do not?
- Positive catalyst is to speed up the negative catalyst to slow down some reaction must be used to the catalyst otherwise difficult to react
- 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 a catalyst in a chemical reaction?
- A catalyst is a compound in chemistry (it can be an acid or temperature or a base or a metal or anything, pressure anything) that shifts the reaction towards one product or the other... In simple words. If you want to obtain something, e.g. water, then you can obtain it in different timings, ie in 2000 years, but if you want to obtain it in 2 hours instead of 2000 years then you add a catalyst, e.g. you heat the reaction to speed it up, you add an acid, or a base etc. Some catalysts also act on the regioselectivity of a compound thru preferring the formation of a stereo-isomer to another. E.g. if you want to obtain S-Thalidomide instead of R-Thalidomide you use a particular catalyst etc...
- Q: Why is the catalyst in the chemical balance, the rate of change and balance?
- But the positive reaction rate is accelerated, but also speed up the reverse reaction rate, the two increase the same multiple, so the system is still in a stable state, the same balance.
- Q: What are the catalysts that appear in the chemistry experiment?
- Oxygen Oxygen Oxygen Oxygen also used when the catalyst is manganese dioxide MnO2
- Q: Why are catalysts so effective in small amounts?
- By definition, catalysts serve to accelerate certain chemical reactions, by lowering the activation energy required for them to proceed. They are not consumed by the reaction, which is why they are effective in small amounts.
- Q: How to poison the catalyst. What can be done?
- In the reactants or catalyst mixed with a small amount of material, so that the catalyst catalytic capacity of a sharp decline or even loss, this phenomenon is called catalyst poisoning. For example, in the synthesis of ammonia feed gas containing CO, CO2 and H2S, PH3, water vapor and other impurities, can make iron catalyst poisoning; contact with the system of sulfuric acid, if arsenic and selenium oxide (As2O3, SeO2), can make vanadium catalyst Loss of activity. Therefore, it is necessary to purify the feed gas, prevent the poisoning of the catalyst, and also reduce the corrosion of the equipment. The phenomenon of catalyst poisoning is sometimes temporary, the removal of toxicants, the effectiveness of the catalyst can still be restored; sometimes it is permanent, without chemical treatment can not restore catalytic performance.
- Q: Is the enzyme in the enzyme bigger than gold?
- No: A biological enzyme is a biocatalyst that is produced or extracted from a biological organism. The catalyst is a substance that accelerates the chemical reaction and does not change itself in the chemical reaction. In layman's terms, the catalyst is a special substance that catalyzes it. Enzyme as a member of the catalyst family has its own special properties. Each of the biological enzymes will only selectively react to some chemical reactions.
