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.

Esther

The most amazing girl in the world. When you see her beautiful face you feel as though she was a gift from the heavens above. Her smile makes it seem there is no wrong in the world, and when you look into her eyes it feels as if the earth has stopped moving and time just froze in it's footsteps. Basically if you get to meet this girl then you're one lucky guy.

when i saw that gorgous girl down the hall there was no way to describe her exept Esther.
