PPT-1 Ethers and Epoxides

Structure Ethers have two organic groups alkyl aryl or vinyl bonded to the same oxygen atom R groups are identical symmetrical ether R groups are different unsymmetrical ether Oxygen is . 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 1 Phenolic Ethers Alkyl Phenolics Heterocyclic Ethers Larger PAH 500 600 700 800 900 Figure 1 Formation of biomass tars and example of compounds formed Alcohols and Ethers. Alcohols. Alcohols are compounds whose molecules have a hydroxyl group attached to a saturated carbon atom. The saturated carbon may be that of a simple alkyl group . Examples. Or the saturated carbon may be connected to an . 9-4. 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.. 9-11. Methanol:. Formed by catalytic reduction of CO and H. 2. at high temperatures and pressure.. Used as a solvent, a fuel for camp stoves and soldering torches, and as a synthetic intermediate.. Highly poisonous. May lead to blindness or death.. Epoxides. 1. Ethers and Their Relatives. An . ether. . has two organic groups (alkyl, aryl, or vinyl) bonded to the same oxygen atom, R–O–R. .
