A phase transfer catalyst or PTC in chemistry is a catalyst which facilitates the migration of a reactant in a heterogeneous system from one phase into another phase where reaction can take place. Ionic reactants are often soluble in an aqueous phase but insoluble in an organic phase unless the phase transfer catalyst is present. Phase transfer catalysis (also PTC) refers to the acceleration of the reaction by the phase transfer catalyst. Phase transfer catalysts for anion reactants are often

Phases of the French Revolution The French Revolution was a period of radical social and political upheaval in French and European history. It lasted from 1789 to 1799. There were many phases of the French Revolution such as‚ The estates general‚ National Assembly‚ limited monarchy‚ the first french republic‚ directory‚ and the Napoleonic era phase. The Estates General was the first phase which lasted from (1788-1789) and they only met under unique circumstances‚ there elections and meetings

solvent‚ water can be used as either a base and an acid. Explain the structure and behaviour of water Similar to many other substances and liquids‚ water takes on numerous forms. It can either be solid as ice‚ gas as steam‚ and its usual liquid phase‚ water. Water molecules are electrically neutral and V-shaped with molecular formula H2O. In water‚ each hydrogen atom is bound to the oxygen atom by an electron pair‚ which is shared between them; this is known as covalent bonding. This process

Alexandra Coffey M3 Assignment - Summation of Initial Phase What specific characteristics might you expect at the initial phase of the group’s development? In the initial stage of the groups development the specific characteristics that we might see include members learning what is the correct way in which to act and how to trust those around you. All of these individuals are nervous already so there is no need for judgment and ridicule we are here to talk freely and trust that what we talk about

Chapter (9) Single-Phase Motors Introduction As the name suggests‚ these motors are used on single-phase supply. Singlephase motors are the most familiar of all electric motors because they are extensively used in home appliances‚ shops‚ offices etc. It is true that singlephase motors are less efficient substitute for 3-phase motors but 3-phase power is normally not available except in large commercial and industrial establishments. Since electric power was originally generated and distributed

The control phase is aimed at sustaining the improved solutions. We want to standardize the solutions and implementation plan with the company’s lifestyle. We will develop a control plan‚ use statistical process control‚ enact our total implementation plan‚ use a cost-benefit analysis‚ and finally celebrate the success. The use of statistical process control will help us monitor where the new process is and how things are performing. It will show things such as our new standard deviations and defects

A transformer is a static machines. The word „transformer‟ comes form the word „transform‟. Transformer is not an energy conversion device‚ but is a device that changes AC electrical power at one voltage level into AC electrical power at another voltage level through the action of magnetic field‚ without a change in frequency. It can be either to step-up or step down. Transmission System TX1 TX1 Generation Station 33/13.5kV 13.5/6.6kV Distributions TX1 TX1 © MRM 05
