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.

gave it to my mom, she was proud. (shes dead)
My maiden name was Puddy and I just loved this mug that defined what Puddy means! I bought one for my brother as well as one for me… And this is the first time in all of our 70 + years that we have heard Puddy defined! We both are super grateful!
The color of the block highlighting the subject word was labeled "Flamingo Pink", but on the mug, it's actually closer to lilac and the woman I bought this mug for loves the color pink. I do like the apparent permanence of the design on the mug, I'm just disappointed with the inaccuracy of the color.
One day when I was walking down the street a man gave me this mug and said that it will be the best thing that ever happened to me, when I got home I filled the mug with the most delicious coffee and I became a penis. this is the best mug in the world thank you kind stranger for giving me this.
