Sup Lit Ethnics

The most perfect phrase to compliment awesome multi-diverse random strangers as you enter their presence if you appreciate them, and all celebrate a similar culture as an estranged family that meets randomly all the time.

*Pete walks into a room at an annual tech convention party with arms stretched out*
Pete: "Sup Lit Ethnics!"
Martin: "PETE! Sup you lit mofo! Get over here and check out my new phone that I have been showing Sally, Jesse, and Raphael! Do you remember them? Sally and Jesse were here two years ago, and Raphael was here last year."
Pete: "Aww shiz, your phone is on fleek, and of course I remember them!"

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.
