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.

The Urban Dictionary Mug
Loved this mug! So unique and you can edit the text to add something unique.
I gave it to my friend who took money from me and never returned.
I love the fact that I was able to customize my name since I've never been able to find anything with my name. The only downside is it's smaller than I thought it would be (I guess I didn't pay much attention to that), wish it was bigger, only about 10 oz total.
It's simply awesome; and plus, the word means a lot.
Really fast and looks great! Took a chance on Christmas gift and it was a success!
Awesome mug feels really nice good weight and color although I think the shade could be a little brighter when it comes to the highlighter yellow, I am still pleased with the outcome and the fact that a whole passage was so neatly printed onto the product, very pleased with the packaging too! That made it so easy to wrap just in time for Christmas. Who knew!!
okay so the mug was mid but when you have a genz meme and give it to one of the most serious people you know then it's pretty funny
Nice mug, great feel‼️
Perfect!
Good quality ceramic cup! Worth the novelty price!
Perfect gift for my gf
Looks great! Came quick
Gave it to my nerd brother. He used it consume liquid
Love it
as a fan of non-Z-generation-UD (since 2000 more or less) , especially of old-school definitions ("phat!") (as Nick, the more time passes by, the more I reach my inner age = 75 XD) , I totally appreciated the delivery in time for Christmas! (whispering) Perhaps printing quality in the Spain printing company is not as good as in the US, but - hey! - I got it before Christmas as a gift for my thank-God-non-Gen-Z-sister! ;) hugs from the eighties, and from Italy, and thanks!

This is SO cool. Morning coffee will always memorialize my new addition to the English lexicon.
Too inappropriate
