Diethyl ether
Diethyl ether is a solvent that is useful for grignard reactions. It's also an anesthetic. Diethyl ether is highly flammable (even electrical outlets and too high temperatures can ignite it. Diethyl ether must be stored with butylated hydroxytoluene to avoid peroxide products which are explosive. Diethyl ether is also sometimes used for extractions, but other solvents like ethyl chloride, chloroform, toluene, hexane, and dichloromethane are generally preferred. Diethyl ether is synthesized by reacting ethanol with sulfuric acid. This reaction must be carried out at temperatures lower than 150 °C in order to ensure that an elimination product (ethylene) is not a product of the reaction. At higher temperatures, ethanol will dehydrate to form ethylene. The reaction to make diethyl ether is reversible, so eventually an equilibrium between reactants and products is achieved. Getting a good yield of ether requires that ether be distilled out of the reaction mixture before it reverts to ethanol.

I LOVE GETTING THE FUCKING MUG
The wife absolutely loved it for her birthday

Can we really send one to Trump? That's where mine is going. Anyone who gets it will see it as a compliment, I'm sure. Love my mug and love that new "urban dictionary" term: Celebritrash. It'll be in the mainstream dictionaries next week.
My friend saw the message on the cup ordered at a mutual friends house. We think it’s hilarious so had to put it on a coffee cup. Funny, great Christmas present. If she can’t use in public she can always use at home for pens and pencils on her desk!
Bought the "Bump Down" mug for my boyfriend, he thought it was the greatest and couldn't believe I'd actually found something with the phrase on it!
Great mug but i can't manage to get it out of my asshole again
First heard the term “Cheddar Headed” from the song Feel Good by the Gorillaz. Had to look it up and found the definition hilarious and at times very true! So......had to have it! Took it to work and it definitely made an impression. Hahaha!
This was purchased as a gift , and it describes the recipient perfectly . It arrived sooner than expected, and I am very impressed with the quality .
The mug I ordered was exactly as described on the site. The shipping was fast as well. I will buy from these people again.
