Preparing Ether. EQUIPMENT distillation flask water cooled condenser tap funnel thermometer filtration paper rubber tubing ring stand clamp burner asbestos-covered wire gauze ice-bath litmus paper MATERIALS Ethyl alcohol concentrated H2SO4 ****** WARNING 1. During the condensation process, do not forget to cool vapor. 2. Ether is volatile liquid. Close the mouth of filtration flask with the rubber tubing. Place the filtration flask into the ice bath. 3. Do not smell ethers. PROCEDURE 1. Set up the apparatus 2. Place 50ml of ethyl alcohol into the distillation flask. 3. Add 20ml of conc. sulfuric acid into the same distillation flask. 4. Put 25ml of ethyl alcohol into the tap funnel. 5. Heat the distillation flask on asbestos-covered wire gauze. 6. Add ethyl alcohol from the tap funnel at the same rate at which ether distils. 7. Boil 5 more minutes after ethyl alcohol has finished in the tap funnel. 8. Stop boiling. http://www.gonulevi.com/chemistry You asked. Iä-R'lyeh! Cthulhu fhtagn! Iä Iä! |

KMnO4 used for? That sounds like an explosion waiting to happen heating ether with KMnO4? Although I see it on your materials list, I do not see it in the procedure. |

You know what? | Bookmark | |||||
That's a good question. CH3CH2OHOH+HOHOCH2CH3 --H2SO4--> CH3CH2OCH2CH3+H2O Nope, No KMnO4 Here! ![]() Probably should try this one, looks more OTC anyway.

Washing PS starting fluid with hot dH2O ...... | Bookmark | |||||
Washing PS starting fluid with hot dH2O ...... Ether has a little solubility in water because of the two lone pairs on the oxygen bridge, somewhat like 6gr in 100 ml water, if I remember well (don't take this number for granted, check yourself, but it has a little solubility in water, of this I'm sure). Anyway a chem supplier should sell freely ether, last month I bought a 100 ml bottle even in a simple pharmacy....It shouldn't be a problem,unless you ask for 10 liters. |
