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:What is a Catalyst?
Catalyst is a chemical substance which is used in chemical reactions in relatively small amounts to start up or increase the rate of the reaction without being consumed in the process. For example, Sulfuric Acid is used to dehydrate Ethanol to Ethylene. Enzymes in living beings are biological catalysts. Manganese dioxide, used to decompose Hydrogen Peroxide to Oxygen and Water. For detailed answer.... en.wikipedia.org/wiki/Catalysis
Q:what is a catalyst ?
OK- First about what a catalyst does. All reactions require some amount of energy to proceed. For most of of these it is not much and it comes from the reactions immediate environment and we don't notice it. This energy needed is called an energy threshold. Many, if not all, reactions can have their thresholds lowered by something else-platinum-nickle in the cars catalytic converter does this. Catalysts are not used in the reaction so the catalyst, once added, stays there and continues working. By the way, in biology we have organic catalysts (the enzymes).
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: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:A question about the catalyst in a chemical reaction
Heating or increasing the contact surface of the reactants.
Q:Can a catalyst be present in the rate equation?
All the factors that affect a reaction rate, except for concentration and reaction order, are taken into account in the rate equation of the reaction. A catalyst: The presence of a catalyst increases the reaction rate (in both the forward and reverse reactions) by providing an alternative pathway with a lower activation energy. en.wikipedia.org/wiki/Reaction_ra...
Q:Why can the catalyst change the chemical reaction rate?
Change the course of the reaction
Q:A catalyst elevates the rate of a reaction by?
lowering the activation energy needed for the reaction to occur.
Q:How does the chemical equation calculate the quality of the catalyst?
So the reactant mass is equal to the quality of the product, with the quality of conservation
Q:What is the relationship between the catalyst and the chemical reaction?
Enzyme is a biocatalytic biological biomolecule, a biocatalyst that accelerates the rate of biochemical reactions without changing the direction and product of the reaction. That is, enzymes can only be used to change the speed of various biochemical reactions, but not the biochemical reaction itself. Enzyme is a kind of amino acid composed of a special biological activity of the substance, which exists in all live animals and plants, is to maintain the normal function of the body, digest food, repair tissue and other life activities of a necessary material.
