               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: What are the pharmaceutical manufacturing companies now using PT / AL_203 catalysts?
I have a friend working in Hunan, inquire, as if the piece of PT has the most advanced equipment ,,, you can hit 114 inquiries ~!
Q: The properties of scandium
Sci-Scandium (Sc) Basic knowledge Introduction In 1879, Swedish chemistry professor Nelson (LFNilson, 1840 ~ 1899) and Clive (PTCleve, 1840 ~ 1905) were almost simultaneously in rare mineral silica beryllium yttrium and black The mine found a new element. They named this element "Scandium" (scandium), ...
Q: I think doubling the concentration of catalyst will double the rate of a reaction (K2/K1 =2). I want to confirm. This is for my project work. Please reply as soon as possible.
A catalyst speeds up a chemical reaction by providing an alternate reaction pathway with a lower activation energy, thus increasing the number of collisions that can result in the formation of product. When the catalyst is a reactant in the rate determining step, and the reaction is first order in the catalyst, then a doubling of the concentration will double the rate. But if the rate determining step which includes the catalyst is not first order, then doubling the concentration won't double the rate. Then there is the case of a heterogeneous catalyst in which the reaction is essentially zero order in the catalyst. The amount of catalyst won't affect the speed of the reaction beyond the initial increase. The mere fact that the catalyst is present speeds up the reaction.
Q: What is the difference between an enzyme catalyst in a living body and a catalyst in chemistry?
in vivo enzyme activity is regulated in the body, the enzyme activity is regulated control. This is another important feature of the enzyme that distinguishes it from the chemical catalyst. There are many ways to regulate enzyme activity, such as feedback regulation, covalent modification, zymogen activation, allosteric regulation, hormone regulation, and so on.
Q: Is it possible for the different chemical reactions to have the same catalyst?
Right, think about the catalysis of biological enzymes
Q: What kind of chemical substances can seriously damage the ozone layer, as a catalyst or reactants can be?
Hundreds of years ago the news once the industrial production and emissions of ozone generated less way, the ozone layer will still be thin.
Q: What is the difference between biological and chemical catalysts?
Biological catalysis involves an enzyme usually working in conjunction with a co-enzyme. These enzyme/co-enzyme systems are highly specific and are usually only effective for one reaction. Catalysis of non biological reactions is usually much more general and any one catalyst will be effective in many reactions.
Q: Why extract the genome, the digestion is always not cut
Enzymes are proteins that are highly specific and catalyzed in living cells, also known as biocatalysts, which are produced by the organism itself. In the metabolic process, almost all chemical reactions are in the enzyme Catalyzed, and the conditions are mild, the reaction efficiency is extremely high, so that the various substances in the body in constant metabolism, in this sense, there is no enzyme without life. Intracellular synthesis of enzymes mainly in the cell from the catalytic The role of some enzymes after the release into the blood or digestive tract, and where to play its catalytic role, artificial extraction of enzymes in the appropriate conditions can also be in the test tube of its special substrate catalytic role.
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: Which chemical reaction is added to the catalyst in order to slow down the reaction
Edible oil added 0.01% to 0.02% gallate n-propyl ester, you can effectively prevent rancidity
