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:Does all chemical reactions have a catalyst?
Not some reaction without catalyst
Q:how does the catalyst work (to speed up the reaction)??
catalyst takes the reaction through an alternate path(series of reaxns) which has lower activation energy.hence it speeds up ur reaction
Q:What is the principle of the catalyst?
The catalyst can be used as the reaction of the original reaction into multiple reactions, such as two, then the catalyst can be the first reaction of the product, while the second reaction of the reactants, then the overall point of view, the amount of catalyst No change, is to change the reaction process.
Q:why are enzymes called catalysts?
Because they speed up chemical reactions by lower the amount of energy required to start the reaction (called activation energy). A catalyst is something that speeds up a reaction - which is what enymes do.
Q:Is it not the rate to accelerate the addition of the catalyst to the catalyst, and that is why the balance does not move
If the reaction before the catalyst, you can speed up the reaction rate, that is to achieve the balance required to reduce the time, but to balance the system when the same concentration
Q:The addition of the catalyst has no effect on the chemical equilibrium of the movement
Factors that affect the chemical balance of movement are mainly concentration, temperature, pressure and so on.
Q:Copper oxide and ferric oxide can replace manganese dioxide as a catalyst in chemical reaction?
No
Q:I opened catalyst control center and now when i full screen a youtube video it doesnt work?
on the backside suitable hand corner of the small reveal, there's a field with a smaller field in it (suitable of the quantity), press that, it provides you with the finished reveal. you could press the comparable button once you opt for to bypass decrease back. The button would have a crimson X in it this time.
Q:Does the catalyst participate in chemical reactions?
The catalyst only acts as a catalyst in the chemical reaction and does not participate in the chemical reaction
Q:In the chemical reaction, why can the catalyst speed up the reaction rate
Platinum and rhodium catalyzes the conversion of carbon monoxide and nitrogen oxides to carbon dioxide and nitrogen, which are used in the conversion of automobile exhaust gases, and in most cars.
