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.

Ether

A heating appuratus found in the walk in fridge at the depot. Ether should not be confused with a heater, which is an anesthetic found in and around the depot. Both heaters and ether are used by Gauthier on cold winter days.

"Guy, we needs more ether in my orfice because Im froid. Take the heater out of the fridge, because it defeats the purpose to have a heater in the fridge. If I get too cold, I have pains dans my backside and will need ether and heaters."

Dude, have you read the latest chapter in Ethereal Wings on Lost-Woods?

Yeah, Chapter five? It was like 30 pages long, but worth it because it was hilarious.

I wonder if chapter six will have treefrogs with crossbows, or Nozomi and Link were just kidding about that.
