ethel'd 

The act of haggling someone down on their price, if possible to the point where the food is practically being taken out of their children's mouths.
Similar to being a skinflint or jew but much much worse!

"Did you see how Delwin Ethel'd him down?? I think he got it for less than it cost to make and he got the seller to throw in his first born!!! That man is a god!"

Do me an Ethel

Reference to I Love Lucy show. Lucy would always ask her best friend Ethel to help her with some crazy scheme and no matter how crazy it was Ethel would do it!!

Come on, do me an Ethel?

ether day 

a celebratory event that takes place every year on december 4th to commemorate the release of the song "ether" by rapper nas. things to do on ether day: bump ether, bump jay-z crying on hot 97, discuss the long term effects of ether, congratulate people on youtube, etc.

1: damn, twitter, youtube and hip hop boards are filled with this ether shit, what's that?
2: happy ether day

Diethyl ether 

Diethyl ether is a solvent that is useful for grignard reactions. It's also an anesthetic. Diethyl ether is highly flammable (even electrical outlets and too high temperatures can ignite it. Diethyl ether must be stored with butylated hydroxytoluene to avoid peroxide products which are explosive. Diethyl ether is also sometimes used for extractions, but other solvents like ethyl chloride, chloroform, toluene, hexane, and dichloromethane are generally preferred. Diethyl ether is synthesized by reacting ethanol with sulfuric acid. This reaction must be carried out at temperatures lower than 150 °C in order to ensure that an elimination product (ethylene) is not a product of the reaction. At higher temperatures, ethanol will dehydrate to form ethylene. The reaction to make diethyl ether is reversible, so eventually an equilibrium between reactants and products is achieved. Getting a good yield of ether requires that ether be distilled out of the reaction mixture before it reverts to ethanol.

I reacted ethyl magnesium chloride in diethyl ether with acetone, then reacted it with hydrochloric acid, and got 2-methyl-2-butanol.

Dibutyl ether 

Dibutyl ether is an ether that is used for complex grignard reactions where higher temperatures are needed. Dibutyl ether is good for reacting benzyl magnesium chloride (made from benzyl chloride and magnesium turnings in dibutyl ether) with acetonitrile in dibutyl ether at elevated temperatures. Then reacting it with hydrochloric acid to get Phenyl-2-Propanone. Dibutyl ether increases the yield compared to diethyl ether. Dibutyl ether is produced by reacting butanol with sulfuric acid. The temperature cannot be too high, as butanol could dehydrate into butene (1-butene). The ether must be stored with butylated hydroxytoluene as explosive peroxides can form.

I reacted benzyl magnesium chloride with acetonitrile in dibutyl ether and hydrolyzed it with hydrochloric acid to get Phenyl-2-Propanone.

diethyl ether 

(C2H5)2 O or C4H10 O

A colourless, volatile, highly flammable, sweet-smelling liquid hydrocarbon belonging to the ether group. Its primary use is as solvent, starting fluid for engines, cleaner alternative fuel and of course medicinal anaesthetic. Diethyl ether is one of most commonly used ether compound.

Diethyl ether is also isomer of butanol (C4H9OH).
