Product Description:


               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:Exemplify the use of green catalysts in green chemistry
Photocatalytic water generates oxygen and hydrogen
Q:What is the catalyst condition in the chemical equation?
I studied three methods ~ word which can be used to give me a mailbox to the word text to pass you ~
Q:Chemical reactions in the presence of impurities will cause catalyst poisoning
Catalyst poisoning reaction of raw materials contained in the trace impurities to the catalyst activity, selectivity significantly decreased or lost phenomenon. The nature of the poisoning phenomenon is a trace of impurities and the catalytic activity of the center of a chemical effect, the formation of non-active species. In the gas-solid heterogeneous catalytic reaction is formed in the adsorption complex. One is that if the toxic and active components of the role of weak, can be a simple way to restore the activity, known as reversible poisoning or temporary poisoning. The other is irreversible poisoning, it is impossible to restore the activity in a simple way. In order to reduce the side reaction activity, it is sometimes necessary to allow the catalyst to be selected for poisoning.
Q:What are the characteristics of the catalyst in the chemical reaction?
In simple terms: the catalyst itself is involved in the reaction, the quality of the reaction before and after the same, the ingredients do not change. The catalyst can change the rate of chemical reaction, increase the rate of reaction called catalyst, slow the inhibitor.
Q:Chemical "catalyst can speed up the chemical reaction rate of other substances," this sentence right?
Wrong, the catalyst is divided into two kinds, one is to speed up the chemical reaction speed, and the other is the opposite
Q:How does catalyst aid a chemical reaction?
Catalyst just speed up the chemical reaction they don't effect the chemical reaction or its equilibrium.............
Q:NH3 and O2 in the presence of catalyst in the chemical reaction occurred how to write,
4NH3 + 5O2 == 4NO + 6H2O
Q:Chemistry is often said that the catalyst can change the material reaction rate
Rate refers to: the amount of time in the unit reaction, and speed, and the speed simply refers to the speed
Q:Is there a catalyst in the chemical shop?
If it is like vanadium pentoxide, which catalyzes sulfur dioxide, do not sell it because vanadium is highly toxic and most of the catalyst is expensive
Q:What are the chemical reaction conditions in organic chemistry are catalyst and heating, please elaborate
This really does not have omnipotent law, their own more than one point, you can classify to remember, when I was in high school is in accordance with the notes, such as poly, polycondensation and the like. In general, the double triple bond addition, plus halogen is not the conditions, plus HCl, HBr and the like to heat; dehydration reaction generally concentrated H2SO4 heating, dehydration condensation is also; there are some special, such as ethylene added to ethanol Special temperature requirements, it seems that 120 degrees, there are other; other addition poly, polycondensation some need catalyst. The The In short, the conditions are many, in general, you do not go to the high school to do more questions after the feeling, encounter problems do not panic general experience can come out according to experience, this also depends on the usual accumulation, if the equation conditions Wrong to deduct points, it is not worthwhile. There are some questions when the examination will give you some information, whether you know do not know should see clearly, although some of the reaction but the subject to the conditions are not the same, when you do according to the title to write conditions, this will not wrong. In addition, thank you for your help, I do not seem to know you
