- Q:Chemical production of iodine and magnesium with water as catalyst!
- In the 250mL three bottles were equipped with spherical condenser and constant pressure dropping funnel, in the condensate tube connected to the anhydrous calcium chloride drying tube. The flask was placed with 1.5 g of magnesium chip and a small tablet of iodine, 10 g of bromobenzene and 30 mL of anhydrous ether were mixed in a constant pressure dropping funnel. First 1/4 of the mixture into the flask, a few minutes later see the magnesium surface of the bubble generated, the solution was slightly cloudy, iodine color began to disappear. If no reaction occurs, use a hot water bath. After the start of the reaction, stir, slowly dropping the remaining bromophene ether solution, dropping the rate to keep the solution was slightly boiling state, after adding, in the water bath to continue reflow 0.5h, magnesium tablets full effect.
- Q:Palladium is the main catalyst in chemistry?
- Palladium in the chemical mainly to do the catalyst; palladium and ruthenium, iridium, silver, gold, copper and other alloy, can improve the palladium resistivity, hardness and strength, used in the manufacture of precision resistors, jewelry and so on. While the most common and most commercially available palladium jewelery is palladium.
- Q:How does the catalyst generally add to the organic chemical reaction?
- In the case of heterogeneous catalysis, the specific surface of the catalyst, in addition to the activity of the catalyst, is an important factor in determining the reaction rate, which means that the specific surface for catalysis is large and the reaction is as fast as the whole. So the overall principle in understanding the activity of the premise of the catalyst, would like to quickly add a little more.
- Q:Please name 2 common examples of catalysts.Thank you?
- Well, there's Adam's Catalyst (PtO2) which is one of the most used catalysts.
- Q:the process of which the heterogeneous catalyst work in vehicles. a step by step instruction in how they work. :)
- The Reduction Catalyst The reduction catalyst is the first stage of the catalytic converter. It uses platinum and rhodium to help reduce the NOx emissions. When an NO or NO2 molecule contacts the catalyst, the catalyst rips the nitrogen atom out of the molecule and holds on to it, freeing the oxygen in the form of O2. The nitrogen atoms bond with other nitrogen atoms that are also stuck to the catalyst, forming N2. For example: 2NO =N2 + O2 or 2NO2 =N2 + 2O2 The Oxidization Catalyst The oxidation catalyst is the second stage of the catalytic converter. It reduces the unburned hydrocarbons and carbon monoxide by burning (oxidizing) them over a platinum and palladium catalyst. This catalyst aids the reaction of the CO and hydrocarbons with the remaining oxygen in the exhaust gas. For example: 2CO + O2 =2CO2
- Q:What are the methods of catalyst characterization?
- Physical means, is commonly used detection means, infrared, ultraviolet, electron microscopy, X-ray diffraction, nuclear magnetic, etc., of course, including a variety of conventional inability analysis.
- 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:What is the microcosmic principle of the catalytic reaction in the chemical reaction?
- It is actually directly involved in the reaction, but, after the reaction, it has become a product out, the equivalent of no response
- Q:Characteristics and types of catalysts?
- Catalysts don't undergo any change. and types of catalysts - 1) Homogeneous Catalysts ( Having same phase that of reactant, product i.e. reactant and product and catalysts all are either liquid or gas or solid.). 2) Hetrogenrous Catalysts (Different Phase than that of reactant and product. 3) Autocatalysts (reaction proceed catalysed as product is formed or product catalyse the reaction.)
- Q:What about the chemical reaction of the catalyst if there is no catalyst?
- Slow response or no reaction
