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.

- Q: Organic chemical concentration of bromine and liquid bromine What is the difference between the conditions in the iron as a catalyst can not be reacted with toluene to produce tribromotoluene? Is it possible to work with phenol to produce tribromophenol?
- The concentrated bromine water is a bromine aqueous solution and the liquid bromine is pure bromine. Only liquid bromine can produce tribromotoluene, and to add iron powder as a catalyst, and the main production is to lead bromotoluene and p-bromotoluene, tribromotoluene this content is very small.
- Q: What is a catalyst in a chemical reaction?
- I didn't actually need to know what a catalyst was for my chemistry exam just what it does. A catalyst is something that speeds up a chemical reaction.
- Q: How do I write about the ion equation?
- 4NH3 + 5O2 == 4NO + 6H2O
- Q: What are the properties of the catalyst (eg, specificity)?
- The composition, chemical properties and quality of the catalyst itself do not change before and after the reaction; its relationship with the reaction system is as highly selective (or specific) as the relationship between the lock and the key. A catalyst is not for all Chemical reactions are catalyzed, for example, manganese dioxide in the thermal decomposition of potassium chlorate in the catalytic role to speed up the chemical reaction rate, but other chemical reactions do not necessarily have a catalytic effect.Some chemical reaction is not only a single catalyst, such as potassium chlorate Thermal decomposition can play a catalytic role in the magnesium oxide, iron oxide and copper oxide and so on.
- Q: Where are they good catalysts and why?? THanks!
- A catalyst is a substance that speeds up a chemical reaction by providing an alternate reaction pathway with a lower activation energy. Catalysts appear not to take part in the reaction. Frequently, catalysts are not very reactive. Acids and bases, on the other hand, are very reactive. Acids (as H+) and bases ( as OH-) sometimes function as catalysts in some organic reactions. They appear to be catalysts because in the course of the mechanism H+ or OH- is regenerated.
- Q: okay im doing a project for my classroom about catalyst and i have to draw a picture but when i looked up on google i just saw a bunch of random stuff and a couple were metal so thats why im asking this question. :)

- Q: Can manganese dioxide be used as a catalyst for various chemical reactions?
- he catalyst does not participate in the reaction, such as on the platinum - rhodium alloy network, nitrogen and hydrogen reaction to produce ammonia .Piplatin - rhodium alloy network in the process of providing electrons (or similar effects, the specific is not clear, but does not react itself), the reaction Before and after the platinum - rhodium alloy network shape has not changed.
- Q: The chemical reaction equation of methanol heating and oxygen in the presence of catalyst
- Catalytic oxidation of formaldehyde
- Q: Why extract the genome, the digestion is always not cut
- The specificity of enzymes is very strict, those compounds that are considered symmetric in organic chemistry such as glycerol, ethanol, citric acid, etc., are asymmetric (even with the same groups) when they are used as substrates for enzymes, That is, their location in space, after all, different (available "three-point landing" theory explained, 1948 Oqston proposed).
- Q: What kind of chemical reaction requires a catalyst?
- Too much reaction, and basically related to the industry
