2-chloromethylthiophene
2-Chloromethylthiophene is used as an intermediate to 1-(2-thienyl)-2-Propanone. In a 2-l. beaker surrounded by an ice-salt bath , and fitted with a mechanical stirrer and a thermometer, are placed 420 g. (392 ml., 5 moles) of thiophene and 200 ml. of concentrated hydrochloric acid. A rapid stream of hydrogen chloride is passed continuously into the mixture with vigorous stirring. When the temperature reaches 0°, 500 ml. of 37% formaldehyde solution is added at a rate that will permit the temperature to remain below 5°. The addition requires about 4 hours. When all the formaldehyde solution has been added, the mixture is extracted with three 500-ml. portions of ether. The ether extracts are combined, washed successively with water and saturated sodium bicarbonate solution, and then dried over anhydrous calcium chloride. The solvent is removed by distillation, and the product is distilled under reduced pressure through a 50-cm. fractionating column. The product boiling at 73–75°/17 mm. is collected. The yield is 257–267 g. (40–41%) of a colorless oily liquid.
The Urban Dictionary Mug
i love the schizophrenia mug its amazing
This cute mug reminded me of a quote from an obscure biography I found quite by accident in a tiny hole-in-the-wall 2nd hand shop in Portland, ME in 1987: 'The Life and Times of Lazarus of Bethany'. Quote: " We are all walking wounded held together by the scars of our forbearance and the charity of our sisters and brothers." Truer words have never been said.
Love it . Its me down to a T
unlike most mug customization, you can say whatever the fuck you want. Bravo!
i liked that the mug had my name on it and a funny definition, i will definitely buy some for my friends(with their names of course).
I bought it as sort of a gag gift for my son and his new girlfriend and they loved it
I haven't even bought it, it smells nice
nice quality, vivid image
What's funny is the saying that everyone searched for is the one that popped up on the cup. So all the weird gross sayings that people are commenting on are completely out of context to everyone seeing their comment.
I would buy a morbillion of these mugs.
Coffee is good with a banana (minus the Shimflins!)
It was a good gift
AMAZING MUG. Love a good tutti cup in the morning
Great product The mug is of very good quality. Highly recommended!
Guys do i buy a sex mug?

EVERY mug I have ordered online through Urban Dictionary has exceeded my expectations! Each (5) is of a very high quality: Clear/Clean printing (ink, color, sharpness, clarity), and Outstanding craftsmanship ("feels" good to hold, and you can tell it "ain't made cheap"). Your company should be proud, indeed.
love it
