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:Is there a catalyst in the chemical shop?: If it is manganese dioxide what is sold because it is not dangerous not expensive

Q:What is a chemical catalyst?: A substance that participates in chemical reactions but does not change the quality and chemical properties. It can change the reactant activation energy, speed up or slow down the reaction rate.

Q:What is the reaction of hydrogen peroxide to add manganese dioxide?: There are bubbles produced

Q:What is the PTC catalyst in chemistry?: PTC, Phase Transfer Catalyst, phase transfer catalyst PTC is the role of a reaction from one phase to another phase to participate in the reaction to promote a solvent can be dissolved in organic solvents and a solvent insoluble in the ion Reagents react between the two reagents. And this type of reaction is collectively referred to as phase transfer catalytic reaction.

Q:Why the catalyst is required to have a large surface area and a rich pore structure: Has a large surface area, is the reactants and catalyst contact more fully, improve the catalytic effect

Q:Does the nature and quality of the catalyst itself change before and after the chemical reaction?: No, but in some cases it may produce catalyst poisoning

Q:Which branch of chemistry or what specialty can study the catalyst: Analytical Chemistry: Application of Catalysts in Analytical Chemistry, Component Analysis of Certain Natural and Synthetic Catalysts

Q:Several experiments were carried out using catalysts: Hydrogen peroxide in the manganese dioxide as a catalyst for decomposition reaction: 2H2O2 == MnO2 == 2H2O + O2 ↑ (laboratory oxygen principle)

Q:The catalyst before and after the reaction of the quality and nature of the same, does it mean that a little catalyst can be all the substrate reaction? Such as: one gram of MnO2 can reflect the infinite H2O2?: Catalyst before and after the reaction of the same quality,

Q:and what type of macromolecule are they made of? thanks!: A catalyst is any substance that speeds up a chemical reaction without otherwise changing the outcome of the reaction. Catalysts do this by lowering a reaction's activation energy (which is the energy barrier that must be overcome before the reaction can proceed spontaneously). Catalysts are not permanently changed by the reactions they catalyze, so one catalyst could reasonably catalyze the same reaction many times over. Enzymes are biological catalysts because they lower the activation energy of metabolic reactions (and therefore increase their rate). Every enzyme has an active site that is specific for a particular substrate, or for a small related group of substrates. When the correct substrate binds to the active site, the enzyme catalyzes a particular reaction and releases new products. Substrates that don't match the shape of the enzyme's active site usually won't be affected by the enzyme. Enzymes are proteins, which are in turn polymers of amino acids. The sequence of amino acids in an enzyme, as well as the three-dimensional structure of the polypeptide chain, are essential for determining the enzyme's functionality. I hope that helps. Good luck!
