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:What is positive and negative catalyst in chemistry?
- Positive catalyst can speed up the reaction rate, negative catalyst can slow down the reaction rate
- Q:What is the catalyst for industrial aluminum electrolysis?
- 2AlCl3 (melt) = power = 3cl2 + 2al by-product is chlorine
- Q:about 1-3 sentences on this will do thank you
- Enzymes Are Classified As
- 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 are the characteristics of the catalyst in the catalytic reaction?
- The role of the catalyst in the chemical reaction is to change the rate of chemical reaction, and its own quality and chemical properties do not change.
- Q:How does active charcoal catalyze in some chemical reactions?
- It is a carrier, because its particles are small (micron level, nano-level), has a relatively large surface area, can be loaded on the catalyst to provide more reaction sites. Although called activated carbon, but its catalytic aspects of the relevant business reports.
- Q:Are biological enzymes harmful to humans?
- Recently, people are increasingly interested in the use of enzymes in cosmetics, not only from a technical point of view, but also from the market prospects and consumer awareness of these seemingly effective raw materials. Enzymes have been used in laundry detergent for more than 20 years and are linked to long-term performance with the ability to provide and enhance strong stain removal capabilities. According to some speculation, their positive response in the market may be interpreted as satisfying the aging population, the pursuit of younger needs to enhance the performance of cosmetics. The natural shedding process of the skin is controlled by the enzymatic reaction, and the specific enzyme dissolves the cell desmosomes that release the dead epidermal cells. These enzymes are produced in dead keratinocytes. Their active sites are phagocytosed with mercapto groups, and cleavage of peptide bonds in a manner similar to that of thio-glycolic acid and mercaptoalanine (plus derivatives) when the hair is broken. Use these types of enzymes and it
- Q:i know that the catalyst is not react in an reaction,,,so that i don't why could it speed up the reaction?? Further, how does the scientist determine the catalyst for certain reaction??please give me more example....i really want to know it! i do not have any idea about this...so hope your answer will help me....thanks!
- catalyst takes the reaction through an alternate path(series of reaxns) which has lower activation energy.hence it speeds up ur reaction
- Q:Chemistry teaching and learning a bit difficult, thank you
- 2NO + 2CO = 2CO2 + N2
- Q:and can you give me an example of it .. please give it in easy terms if you can. thanks
- A catalyst is something that speeds up a reaction. Heat is a catalyst. An example is the catalytic converter in a car, it speeds up the reaction and makes the fumes coming out not as toxic.
