Properties: Dark-green Power. Density is 1.26g/ cm3 . flashing point is 260°C. Soluble in chloroform, benzene and carbon bisulfide , a little soluble in acetone, insoluble in water.
Applications: Mainly use in styrene- butadience rubber, chloroprene rubber and chlorosul-fonated polyethylene rubber. Avoiding the rubber crack for the sunshine and ozone, promoting the heat-resistant of chloroprene rubber and chlorosul-fonated polyethylene rubber. In plastic industry, it can be used as stabilitant and ozone-resistant agent for high polymer materials. It has advantage of stability for polypropylene fibre , thin film and narrow belt, but it will make the products appear yellow-green color. The use level is 0.3～0.5%. NDBC is regulated for use in articles in contact with food as specified.
Packing:Coextruded paper bags lined with polyethylene film bags. Net weight 25 kg per bag.
Storage:Store closed containers in a cool, dry, well-ventilated area. Avoid exposure to direct sunlight.
- Q:What chemical reactions can water do the catalyst?
- Many solid and solid reactions can be converted into reactions between liquids, which speeds up the reaction rate, and perhaps the water here is the catalyst.
- Q:Is the catalyst considered a chemical reaction?
- The catalyst is involved in the reaction, but in the reaction process is a step in the effect of its shape has not changed, so that did not participate in the reaction.The role of the catalyst is to reduce the activation energy of the reaction, the original one reaction into two or Multiple reactions, each sub-reaction of the activation energy is very low, the reaction is very good, the effect is the total reaction faster. Hope to adopt
- Q:Is the reaction of the exhaust purification of cars (carbon monoxide and nitrogen
- Can not react
- Q:I need to name 3everyday catalysts for my chemistry homework. I don't want anything complicated there must just be 3 easy ones out there... Then could you please state what each one is used for? Please do it like this, e.g.Hello ; used to say hi to someone. I know that's a bad example but please!!
- Hello ; Chemical catalysts are substances that increase the rate of reaction (while remaining themselves chemically unchanged: Polyethylene, the polymer used to make everything from: 1. garbage bags and 2. grocery bags, to 3. squeezable bottles, to 4. cable insulation, is made by passing ethylene gas over a catalyst. Most other polymers are made in the same (or similar) way. Synthetic rubber, nylon, polyester, PVC, teflon, etc. It's not hard to think of 10 uses for these catalyst-produced materials alone... e.g. : 5. rain coats 6. pantyhose 7. water pipes 8. bouncy balls 9. non-stick surfaces and pads 10. saran wrap 11. food containers 12. cell-phone and laptop cases 13. cheap wigs 14. fishing line... 15. Enzymes are Biological catalysts: 16. beer and 17. bread are typically made with yeast, a living organism containing enzymes I hope this helps!
- Q:What is the nature of the chemical catalyst?
- The nature of the catalyst is to play a catalytic role in reducing (or increasing) the anti
- Q:What is the catalyst in the end?
- You said the chemical catalyst or Ati graphics card catalyst? If the above is enough to explain the above, if it is the latter, that is, the meaning of the graphics card, Ati's graphics drive like a catalyst
- Q:Co and No form a chemical equation for Co2 and No2 under the action of a catalyst
- Write the catalyst on the horizontal line, where NO is the oxidant and CO is the reducing agent
- Q:what is the role of a catalyst in a chemical reaction?
- A catalyst speeds up a chemical reaction by providing an alternate reaction pathway with a lower activation energy. Since the activation energy is lower, more product will be formed in the same amount of time. Chemists used to assume that a catalyst somehow sped up a reaction without being consumed in the reaction. We now know that a catalyst will be a reactant in one step of a reaction mechanism, and will be a product in a subsequent step in the mechanism, so that it **appears** that the catalyst does not take part in the reaction. ======== Follow up ========= Remember, it is customary to cite one's sources when quoting from another source or when simply copying large passages from Wikipedia or some other web page.
- Q:Is it possible for the different chemical reactions to have the same catalyst?
- Right, think about the catalysis of biological enzymes
- 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.)
