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.

Sister: This meeting was to discuss the rough draft of my essay, where we discussed the subsidiary questions I added in my rough draft. We also discussed the relationship between my main title and the real-life situations I chose to use in my essay. We discussed the structure of my essay as well, specifically the Math AOK section and how it relates to the contradiction of the title. This second meeting was particularly helpful in discussing the implications of my essay claims and how to apply the title across various areas of knowledge. There were many sections of the essay that could have been cut down in wordiness and the ways of knowing required further and more in-depth analysis.

Me: Woah! TLDU!
