β-unsaturated ketones under catalytic of alkalis. These kinds of reactions are called Claisen-Schmidt condensation reaction. It is an important approach to grow the carbon chain and can be used to synthesize aromatic compounds which have two different function groups on their side chains‚ or the aliphatic system intermediates which have several benzenes. This experiment will synthesize dibenzylidene acetone by the reaction of benzaldehyde and acetone under the catalytic of alkalis. Dibenzylidene

Six Factors Affecting the Performance of an Enzyme Enzymes are considered catalysts; substances that increase the rates of reactions. Enzymes are responsible for thousands of metabolic processes that involve the sustainment of life‚ one common one is simple food digestion. Without enzymes‚ digestion would occur too slowly for life to continue. Enzymes maintain a protein structure consisting of one or possibly more than one polypeptide chains of defined primary structure‚ and take up a characteristic

reaction is shown as: The mechanism of the Suzuki reaction is best viewed from a generated catalytic cycle‚ which is shown below: Figure 1: A generalized palladium catalytic cycle for the Suzuki reactio.2 This cycle states the Suzuki reaction is generally achieved by three steps: oxidatice addition‚ transmetalation and reductive elimination.2 Oxidative addition is the rate determining step of the catalytic cycle. The palladium catalyst couples with the p-iodophenol which results in an organopalladium

repellents transform into ozone-depleting agents.3 Chlorofluorocarbons stay in the atmosphere for several decades due to their long tropospheric lifetimes. These compounds are carried into the stratosphere where they undergo hundreds of catalytic cycles with ozone.4 They are broken down into chlorine atoms by ultraviolet radiation.5 Chlorine acts as the catalyst for breaking down atomic oxygen and molecular ozone into two molecules of molecular oxygen. The basic set of reactions that

on profits and on countries that have not made the transition yet from leaded to unleaded gasoline for their cars and machinery. Outside the industrialized world‚ there are not enough refineries capable of producing unleaded gas‚ many cars had no catalytic converters‚ and if the cars ran on lower-octane unleaded gasoline‚ it would create more pollutants. The best option is for us is to aggressively phase out of the market place with a five year deadline. In the meantime‚ we will push the governments

explaining why and how they will be used is the next chapter. The implementation of the PIP will need to be expanded on in depth to ensure clear reasoning for its effectiveness. Exploring the ethical issues will also need to be considered to allow the toolkit to be suitable for a range of service users. As this PIP is a proposed plan‚ no primary data can be collected‚ however‚ it is necessary to explain how results would be presented‚ using graphs and tables‚ known as the data analysis and presentation
