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:Which branch of chemistry or what specialty can study the catalyst
Inorganic Chemistry: Preparation, Synthesis, Structure and Catalytic Reaction of Inorganic Catalysts and Catalyst Carriers
Q:What is a catalyst/catalase? help?
Catalysts and catalase are two different things, and the definitions that you listed are correct. A catalyst is something that speeds up the rate of a chemical reaction. Many chemical reactions occur naturally and do not require any energy, but they occur so slowly that they are not useful, and catalysts can be used in cases like this to speed up the process. For example iron metal exposed to oxygen and water turns to rust, but if you need a lot of rust by tomorrow, leaving a chunk of iron out in the rain is not a practical solution because it will take too long to convert all that iron metal into rust.
Q:Is the catalyst considered a chemical reaction?
The middle school textbook defines that the catalyst itself does not participate in chemical reactions
Q:Pls help me define a catalyst.?
A substance which speeds up or slows down a reaction without taking part in it.
Q:When there is a catalyst in the chemical equation, it is not necessary to match the atoms of the catalyst
No, the catalyst is written above the equal sign, not the reactants, nor the product
Q:Is it possible for the different chemical reactions to have the same catalyst?
Just as manganese dioxide can catalyze the decomposition of molten potassium chlorate can catalyze the decomposition of hydrogen peroxide, but this is not necessarily the same as the catalyst for the production of the same product, but for the enzyme in order to ensure that the growth of the orderly all have a single Enzymes can only catalyze an organic matter
Q:The addition of the catalyst has no effect on the chemical equilibrium of the movement
Factors that affect the chemical balance of movement are mainly concentration, temperature, pressure and so on.
Q:What is the difference between biological and chemical catalysts?
catalysts which catalyze the chemical reactions taking place in human body such as enzymes are called bio-catalyst and other one's which are generally used in laboratory by chemists for multiple type of reactions are chemical ctalysts
Q:A catalyst?
A catalyst does not ever become part of the chemical change. As far as I know, it always speeds up the reaction, but I could be wrong on that if there is only one correct answer. For sure, it's never changed by the reaction. That is part of a catalyst's definition.
Q:How the catalyst accelerates the chemical reaction
The catalyst is the catalyst that accelerates the chemical reaction by accelerating the chemical reaction
