Properties: white or light yellow powder (granule) with a little bitter, no poison. The density is 1.50, Melting point above 170℃,slightly soluble in benzene, chloroform and ethanol, is not soluble in water petrol. And ethyl acetate. Good storage stability.
Application: Given flat, moderately fast cures in NR and SR. Also used in a wide range of general purpose rubber. Non-staining and non-discolouring in "white" socks; used as a plasticizer and retarder in polychloroethylene rubber. Secondary acceleration is usually required for synthetic polymers. Better scorch safety than MBT.
Packaging: 20kg plastic woven bag, paper with plastic film bag, kraft paper bag or jumbo bag.
Storage: e product should be stored in the dry and cooling place with good ventilation, avoiding exposure of the packaged product to direct sunlight. The validity is 2 years.
Note: The product could be ultra fine powder based on customer accurate requirement.
- Q: Biological enzymes and chemical catalysts of the differences in the source, nature and catalytic characteristics of the different, specific point
- Biological enzyme catalytic reaction conditions are mild, high selectivity, can not be infected
- Q: What happens to a catalyst after a chemical reaction?
- If it is only a catalyst, then by definition it will still be there at the end.
- Q: What is the catalyst condition in the chemical equation?
- I studied three methods ~ word which can be used to give me a mailbox to the word text to pass you ~
- Q: Seems intuitive that it wouldn't, but I dunno the qualitative difference between activation energy & Gibbs free energy. I'M TOO LAZY TO GOOGLE I GOTS STUFF TO DO
- A catalyst can change the activation energy not the Gibbs energy. The Gibbs energy is the energy difference between the initial state and final state. A catalyst cannot change that. Imagine you are driving from school to home. How you drive do not change the height difference between the school and your home. However, a catalyst can change your path which can change the routine you drive from school to home. So if there is a hill in between your school and you home, you have the choice to drive through it or drive around. Here is a picture: upload.wikimedia.org/wikipedia/co... A catalyst can change the height of the barrier, but cannot alter the initial or final state.
- Q: Could God be Discribed as a Catalyst?
- It depends on the context. A catalyst for what? A catalyst being (from a scientific point of view anyway) something that speeds up the rate [of a reaction] without itself being altered. In that respect you could view God as being a catalyst for war, or religious hatred. The counter argument being that it is religion (ie. the interpretaion of God) which is the catalyst. And not to be too negative, God could be seen as a catalyst for good; many of the charitable organisations in the world are theistic in some way. Point is, I'd say that religion, rather than God himself, is the driving force. I don't believe in God, but I ain't, like, zealous about it.
- Q: Why are catalysts so effective in small amounts?
- Catalysts don't get used up in reactions. Because of this, a single catalyst molecule can function again and again. Some catalysts are better than others for a given reaction. More effective catalysts reduce the time taken for 1/ the rate of travel of the molecule to the active site, 2/ the time the reaction takes, or 3/ the time it takes for products to diffuse away, or 4/ a combination of the above. The more effective a catalyst is in these factors, the less is needed to make it equally effective.
- Q: Does the nature and quality of the catalyst itself change before and after the chemical reaction?
- A catalyst will induce a chemical reaction to change, leaving the chemical reaction faster or less
- 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.
- Q: Write a chemical formula in a chemical laboratory without the use of a catalyst for oxygen
- 2KMnO4 = Δ = K2MnO4 + MnO2 + O2 ↑
