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:Why are catalysts so effective in small amounts?
Catalysts don't get used up in reactions. Because of this, a single catalyst molecule can function again and again. Some catalysts are better than others for a given reaction. More effective catalysts reduce the time taken for 1/ the rate of travel of the molecule to the active site, 2/ the time the reaction takes, or 3/ the time it takes for products to diffuse away, or 4/ a combination of the above. The more effective a catalyst is in these factors, the less is needed to make it equally effective.
Q:Carbon monoxide and nitrogen dioxide in the catalyst conditions of the chemical equation
NO + 2CO = 2CO2 + N2 reaction is exothermic. Conditional catalyst
Q:enzymes and catalyst are....?
enzymes help biochemical reactions proceed at a faster rate than normal in a physiological system, catalysts or sometimes referred to as subunits, metals and other ligands, bind enzymes, and can have a positive and negative effect on the rate of a reaction. search them on wikipedia!
Q:Could God be Discribed as a Catalyst?
It depends on the context. A catalyst for what? A catalyst being (from a scientific point of view anyway) something that speeds up the rate [of a reaction] without itself being altered. In that respect you could view God as being a catalyst for war, or religious hatred. The counter argument being that it is religion (ie. the interpretaion of God) which is the catalyst. And not to be too negative, God could be seen as a catalyst for good; many of the charitable organisations in the world are theistic in some way. Point is, I'd say that religion, rather than God himself, is the driving force. I don't believe in God, but I ain't, like, zealous about it.
Q:Explain, using an example, how a heterogeneous catalyst works?
Because of the production of photochemical oxidants from NOx reacting with hydrocarbons in sunlight Noxer blocks are used to rid the NOx from the surroundings through The titanium dioxide (TiO2) on the bocks absorbs ultra-pink radiation from daylight which excites its electrons to a bigger orbital. On the outside of the crystals of TiO2 a reaction happens between oxygen and a high power electron from the TiO2. O2 + e־ --O2 ־ The excessive vigor electron is then given back to the TiO2 when water then reacts with the oxygen to present H2 O + O2 --H+ + O2 ־ + OH Nitrogen dioxide is oxidised to nitrate ions as a result of the hydroxyl radical being an awfully strong oxidising agent NO2 + OH --H+ + NO3 ־ The superoxide from response 3 also varieties nitrate ions from nitrogen monoxide. NO + O2 ־ --NO3 ־ This nitrate is washed away through rain or combines with the concrete within the block.
Q:Why are enzymes classified as organic catalysts?
a catalyst is something that makes a reaction go faster than it normally would. An enzyme is a catalyst; it has all the parts for the reaction on it and help organic materials break down or transfer energy or whatever reaction it needs.
Q:Are biological enzymes harmful to humans?
A biological enzyme is a biocatalyst that is produced or extracted from a biological organism. The catalyst is a substance that accelerates the chemical reaction and does not change itself in the chemical reaction. In layman's terms, the catalyst is a special substance that catalyzes it. Enzyme as a member of the catalyst family has its own special properties. Each of the biological enzymes will only selectively react to some chemical reactions. A biological enzyme is equivalent to a key that opens a complex compound whose importance is that its unique structure or multidimensional shape matches a part of the group. Once these two parts are combined, the specific chemical bond in the group molecule changes as if the lock was opened. When the reaction is completed, the enzyme is released and repeated with the next group, followed by repeated repeats. Many chemical reactions in the normal temperature conditions, the reaction is very slow so that the whole process is difficult to be perceived.
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.
Q:Chemistry is often said that the catalyst can change the material reaction rate
The rate is related to the concentration of matter, the velocity is physically, is the vector, has the direction
Q:What are catalysts and enzymes?
enzymes are like chemical scissors that break up starch inside your body they work best at 37'c which is body temperatur i think they are in the stomach? don't know for sure hope this helped as for catalysts i dont know
