Properties: White, light gray powder or granular. The density is 1.29. Soluble in benzene, acetone, chloroform, CS2 partly soluble in alcohol, diethyl ether, CCI4 insoluble in water, gasoline and alkali with lower concentration. Meeting hot water becomes to dimethylamine ammonium and CS2. Be sensitive to skin and pneogaster
Application: Can be used as a single accelerator, as a secondary accelerator or as a sulphur donor in most sulphur-cured elastomers. Scorchy and gives fast cure rates. Produces an excellent vulcanisation plateau with good heat aging and compression set resistance in sulphurless and EV cure systems Good color retention is obtained in non-black vulcanisation. A valuable secondary accelerator for EPDM. May be used as a retarder in the vulcanisation of polychloroprene rubber with ETU and also be used as bactericide and pesticide

Storage: The 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 ultrafine powder based on customer accurate requirement.
- Q: Always speeds the reation ratedoes not affect the reation rateundergoes a chemical changedoes not become part of the chemical changealways slows the reation rate
- 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: Characteristics and types of catalysts?
- Catalysts don't undergo any change. and types of catalysts - 1) Homogeneous Catalysts ( Having same phase that of reactant, product i.e. reactant and product and catalysts all are either liquid or gas or solid.). 2) Hetrogenrous Catalysts (Different Phase than that of reactant and product. 3) Autocatalysts (reaction proceed catalysed as product is formed or product catalyse the reaction.)
- Q: What is the difference between electrocatalysis and general chemical catalysis?
- General chemical catalysis is a catalyst, and electrocatalysis also need to be carried out under the conditions of the electric field
- Q: What is the nature of the chemical catalyst?
- Catalyst is the chemical reaction can change the reaction rate of other substances, and its own quality and chemical properties in the chemical reaction before and after the material has not changed Some catalyst can really slow down the reaction rate, the book said only refers to the usual circumstances , In general, junior high school and high school teaching into the do not do special instructions are understood to speed up the reaction rate. It is only necessary to know that the catalyst is not only used to speed up the reaction rate. Once the reversible reaction reaches equilibrium, adding the catalyst does not break the balance, but at the same time accelerates the forward and reverse reaction rates. The degree of acceleration is the same.
- Q: What suitable catalysts can I use for the reaction between Hydrochloric acid and zinc metal?
- catalysts are substances that alter the rate of a reaction.a suitable catalyst would be finely divided platinum.
- Q: CO and NO react under the action of a catalyst to generate chemical formulas for CO2 and N2.
- N from +2 to 0 price 2e * 2
- Q: Which chemical reaction is added to the catalyst in order to slow down the reaction
- CaC2 and water reaction to ethylene plus salt water (slow chemical reaction rate)
- Q: Can the catalyst be a reactant in chemistry?
- In the chemical reaction can change the chemical reaction rate of other substances (both improve and reduce), and its own quality and chemical properties in the chemical reaction before and after the material did not change called catalyst. [From the definition of reactants. To
- Q: how a catalyst can provide a new route in forming the product?
- A catalyst may provide a new route in forming a product. Often the reactants have too much energy and bounce off of each other forming few products. The catalyst may provide a surface where the reactants can settle momentarily in close proximity completing the reaction at an increased rate. The catalyst has been pictured (for illustration only) as a surface filled with grooves and when the reactants settle within the grooves (forming a film?) they are close enough to react rather than bounce off of each other. As such the catalyst facilitates the reaction without being used up in the reaction. The catalyst may become 'poisoned' with other molecules that interfere with the desired reaction and the reactants may have to be relatively pure to protect the catalyst.
- Q: If possible can anyone give me information on the active site, substrates, products, and the energy of activation as part of the answer?Responses greatly appreciated! Thankss! 10pts to best answer!
- To make it simple unlike the dude above me...enzymes (biological catalysts) lower the activation energy, which speeds up the reaction. EVERY reaction needs a little boost of energy--the activation energy--and enzymes lower that.
