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:On the issue of chemical reaction catalyst
The definition of a chemical reaction rate in a chemical reaction can be changed (accelerated or slowed down) in a chemical reaction, and the quality and chemical properties of the substance itself are not catalyzed before and after the reaction (which will change during the reaction) Also known as catalyst. Its physical properties may change, for example, MnO2 in the catalytic potassium chlorate to generate potassium chloride and oxygen before and after the reaction from the block into a powder. There is also a saying that the catalyst reacts first with one of the reactants and then the two products continue to undergo a new chemical reaction under the original conditions and the reaction conditions of the catalyst reaction product are more favorable than the reaction conditions of the original reactants Changed.
Q:Chemistry: Does the catalyst participate in the reaction?
The current theory is generally believed that the catalyst to participate in the reaction, the formation of intermediates, and then re-decomposition of intermediates to generate the catalyst, so the quality and nature of the reaction before and after the same. Experiments have shown that although the nature and quality of the catalyst remain unchanged, some of its aspects, such as morphological changes, before the reaction of massive, post-reaction powder, indirectly prove the above theory. Now high school to do the problem generally according to the theory. Such as copper oxidation of copper oxide, copper oxide and then oxidation of ethanol to acetaldehyde, itself is reduced to copper, so copper is ethanol oxidation of acetaldehyde catalyst
Q:Why the catalyst after the chemical reaction of its quality and chemical properties unchanged
In fact, the catalyst in the reaction process has become other substances, but after the end of the reaction, the catalyst has changed back. That is, the catalyst is actually involved in the reaction, except that the amount of catalyst being reacted is as much as it did.
Q:High chemistry: Does the catalyst affect the heat and heat of the reaction?
The catalyst that has no effect affects only the rate of reaction
Q:What are the methods of catalyst characterization?
Catalyst characterization is through the physical or chemical detection test means, the structure and nature of the catalyst to give a state description, to help explain the characteristics and characteristics of the catalyst,
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:Are biological enzymes harmful to humans?
Biological enzymes through scientists more than a century of research, usually known as more than 3,000 kinds of enzymes, the current application of biological enzymes in the textile a wide range of technology, fiber modification, silk degumming, raw hemp (ramie, linen, Kenaf) degumming, dyeing and finishing of the desizing, refining, finishing and net cleaning processing, textile printing and dyeing wastewater treatment and garment processing and other aspects of the application. Enzyme technology has a unique advantage in improving dyeing and finishing processes, saving energy, reducing environmental pollution, improving product quality, adding value and developing new raw materials. At present in the textile processing using a wider range of enzyme system
Q:Chemical common sense about the catalyst
Chemical reactions are generally contact reaction, of course, the more contact with the faster response, pore structure is to increase the contact area
Q:Chemical catalyst in several ways
Two, can speed up and slow down
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
