hurricane ethel

Drink of choice of Bay Area rap icon E-40. Here go the recipe, in his own words: "151 Bacardi Dark, Bacardi Light, Triple Sec, Grenadine, pineapple juice, and an empty container of Arrowhead water. Put it all in one and you got some good shit." I assume a Poland Spring bottle will also suffice for those of us on the East Coast.

"If you ain't got your Hurricane Ethel, you best go fetch it ASAP."

the hacker ethic

All hackers have the good ethic and respect for machines that do not belong to them. If you do not have this ethic than you are not a hacker you are a cracker.

Hackers only seek information, and knowledge. Using this for good and to advance their abilities.

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.
