               DOP 

Molecular Formular : C24H38O4
Molecular weight : 390.57
CAS No.:117-81-7
H.S Code : 2917.3200.00
EINECS No.: 204-211-0
Characteristics : Colorless transparent oily liquid, slight odor.

Processing : Injection Moulding

Application : It is one of the most extensively used plasticizers in plastics processing. It has comprehensive properties, such as high plasticizing efficiency, low volatility, UV-resisting property, water-extracting proof, cold-resisting property, and also good softness and electric property. As a fine main plasticizer, it is extensively used in processing polyvinyl choride and ethylcellulose resins to produce plastic film, imitation leather, electric wire, cable wearer, sheet, planet, mould plastic products and. Used in nitrocellulose paints, it can make the ethylcellu lose more elastic and more strong in extracting tension. It can be used as a softening agent of synthetic rubber, such as to make the product easier to rebound and harder to undergo form change under pressure, without affecting of the plastics.

Q:Is there a catalyst for a chemical reaction?
There may be many, but some of the catalytic effect of the catalyst is good, and perhaps some of the catalyst has not been found
Q:In chemistry what is a catalyst and an example?
A catalyst is a liquid or a gas you can add to a substance to make it react quicker and/or upon itself or another chemical. A catalyst can be one chemical you add to another that causes a significant reaction or they could be variables in an experiment (like temperature) can be a catalyst. It could also be a liquid/gas that you add to a substance to neutralize it or make it safe to clean/touch/handle. For instance if you spill chemicals in a biology lab, you have to add a catalyst (generally water or clarifying soap) to make it safe to clean up. Hope I could help.
Q:Have you Read it ? If SoCan You Think Of Any Good Group Discussion Questions ?
no but aOMG i laurie halse anderson! OMG I LOVED HER BOOK FEVER 1793 wooooooooooo that book was aweomse. you should read it
Q:Thorough explanation pls.
Catalyst are the substances which increase the rate of reaction. They do not get consumed in the reaction but they participate in intermediate reactions. The catalyst action can be explained as- Providing alternate energy path- Let us suppose that an endothermic reaction need 15 joules of threshold energy to occur. The catalyst will provide them path which needs less energy. Providing Surface- Many reaction may occur slowly because less contact between the molecules/atoms/ions or due to unavailability of proper structure, in this case the catalyst provide surface for carrying the reactions. There are several other actions which mayn't be necessary for you to understand the basic function of catalyst.
Q:I have just spent CAN$550 to replace a catalyst converter at one end of the muffler. The repairman said I need to replace the oxygen sensor very soon, otherwise, the C.C. will be gone again. Is that true... can someone confirm this for me. Thanks.
ok its not catalyst converter its catalytic converter. next i have not read one answer that is correct a couple are close but no cigar. ok the 02 sensor senses the oxygen content in the exhaust gasses. using the oxygen content it can determine if the engine is running to rich or to lean. the ecm (computer) wants to keep the engine at optimum fuel mileage or keep it stoichometric meaning fuel to air ratio of 14.7:1 the ecm can adjust fuel air ratios by changing the pulse width and the duty cycle or on off time of the injector.it also uses several other sensors to help it like intake air temp (iat) coolant temp (cts) mass air readings if equipped (MAF) or manifold absolute pressure (map) so its not just the oxygen sensor it can make adjustments as need. anyways the oxygen sensor uses a .1 to .9 volt range signal anything below .450 is lean anything above .450 is rich and .4 to .5 is perfect. but ur engine constantly changes and the 02 readings change constantly new cars can take readings as fast as one or two times a second older cars are alittle slower. anyways only replace the 02 sensor if the car is telling u its bad meaning u have a check engine light on and a code that says P 0 . . . bank one sensor one ckt malfunction or bank 2 sensor 1 ckt malfunction u get the idea unless that happens ur 02's are good leave them alone. when they do go bad ur car will run rich and puke alittle black smoke out the exhaust and ur car will smell like rotten eggs. NOW the cat its job is to heat up to 600 + degreees F and burn unburnt fuel from the combustion cycle of the engine when an engine does not burn all its fuel its running rich and bad fuel milage occurs. if the 02 sensor goes out it can heat the cat red hot as the extra fuel being burnt inside it can become extremely hot. most 02 sensor for most vehicles run around 60 bucks not expensive. a car can have 1 to 4 of these and YES if bad and left for too long and can ruin a cat converter.
Q:The greater the chemical adsorption strength, the catalyst activity changes
If the adsorbent is a reactant, then the better the adsorption capacity of the better catalytic effect; but the catalyst surface of the product will generally have adsorption, if this effect has become very strong, then desorption The process will become difficult, the catalytic effect will decline; the other one, if the adsorption of other substances, such as the reaction may produce a reaction or the catalyst will poison the material, it is greatly detrimental to the catalytic effect. The effect is to be controlled in a suitable optimum range for superior, and preferably to be selectively adsorbed.
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:Does the catalyst participate in chemical reactions?
The catalyst does not participate in the chemical reaction, it only plays an auxiliary role.
Q:High school stage which organic chemical reactions do not use catalyst
Olefins, alkynes, making bromine water, potassium permanganate fade.
Q:and can you give me an example of it .. please give it in easy terms if you can. thanks
