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:1. Catalysts can help to bring the reactants together in the correct orientation2. The chemical formula of a catalyst is written on the left hand side (reactant) side of an equation.3. Catalysts can provide a surface on which the reaction occurs.4. Catalysts increase the activation energy.5. Catalysts increase the magnitude of the equilibrium constant, thus favoring product formation.6. "Enzymes" are biochemical catalysts.7. Catalysts increase the rate of a reaction.8. Catalysts are slowly used up during the reaction and need to be replaced.
- 1 (I don't know about 2), 3, 5, 6, 8 are true.
- Q:Comparison of biocatalysts with chemical catalysts!
- (1) The chemical reaction catalyzed by the biological enzyme is generally carried out under relatively mild conditions. (2) The enzyme has the highest activity at the optimum temperature and pH, and the temperature of the biocatalyst is more moderate. And PH high or low, the enzyme activity will be significantly reduced.In general, the animal in the enzyme the optimal temperature between 35 ~ 40 ℃; plant enzyme in the optimal temperature between 40 ~ 50 ℃; animal body Of the enzyme most of the most suitable pH between 6.8.0, but there are exceptions, such as the optimal pH of pepsin 1.5; plant enzymes in the most suitable pH between 4.6.5. (3) acid, Or the temperature is too high, the enzyme structure will be destroyed, so that the enzyme permanently inactivated .0 ℃ or so, the enzyme activity is very low, but the spatial structure of the enzyme is stable, at the appropriate temperature of the enzyme activity can be increased The
- Q:what is a catalyst ?
- anything that speeds up a reaction, chemical or otherwise, between two things
- Q:Please name 2 common examples of catalysts.Thank you?
- Well, there's Adam's Catalyst (PtO2) which is one of the most used catalysts.
- Q:How the catalyst accelerates the chemical reaction
- The catalyst is the catalyst that accelerates the chemical reaction by accelerating the chemical reaction
- Q:Which branch of chemistry or what specialty can study the catalyst
- Analytical Chemistry: Application of Catalysts in Analytical Chemistry, Component Analysis of Certain Natural and Synthetic Catalysts
- Q:Chemistry GCSE what is a catalyst?
- If you just need the GCSE version (it gets far more complicated at A Level, you have to learn about activation energy and all this other crap) then it's just a substance that speeds up a reaction and allows it to happen quicker. but! The catalyst itself also remains unchanged at the end of the reaction (for reasons you probably don't need to know until A Level.) Remember that.
- Q:Horseradish enzyme catalyzed Luminol chemiluminescence reaction
- Disinfectant ah ~ bleach ah ~ ~ take this kind of thing to wash the blood once something can interfere with Lumino identification. So that want to do bad things must be a good plan. Lumino in the presence of copper, copper alloy, horseradish or some bleach in the presence of fluorescence. So if the scene of the crime was bleached
- 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: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
