PPT-ETHERS AND EPOXIDES

Dr Shatha I Alaqeel 108 Chem Learning Objectives Chapter seven discusses the following topics and by the end of this chapter the students will Know the structure of ethers Know the different methods of naming ethers. CHEMISTRY Glycol ethers are produced by reacting one mole of an alcohol with one two or three moles of oxide ethylene or propylene The synthesis routes of two typical glycol ethers are shown below ESeries Example PSeries Example P Series Glycol Ethe 10ItiswidelyknownthatthefullestaccountgivenbyEinsteinoftheclaimthatSRhasthenatureofa`principle-theory'wasinanarticleonrelativitytheoryhewascommissionedtowritein1919forTheTimesofLondon(Einstein,1919).S Bergische Universit Thiols. , Phenols, .

Organic esters are derivatives of carboxylic acids.. Inorganic esters are the analogous derivatives of inorganic acids.. Organic and Inorganic Esters from Alcohols. 9-4. Alcohols react with carboxylic acids to give organic esters.. 9-6. Ethers are prepared by S. N. 2 reactions.. Ethers can be prepared by the reaction of an alkoxide with a primary haloalkane or sulfonate ester under S. N. 2 conditions.. The parent alcohol of the alkoxide can be used as the solvent, however other polar solvents are often better, such as DMSO (dimethyl sulfoxide) or HMPA (hexamethylphosphoric triamide).. Compounds.
