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 spent the money and directly sent this to be the pettest person ever to a person who was doing this to me. It was awesome
It’s a sturdy ceramic mug. A little pricey, IMO, but I really wanted this definition on a mug. ¯\_(ツ)_/¯
Just what is needed for someone’s desk during the pandemic and beyond when they have to “MacGuyver” to make things happen.
Best purchase of my life, it's all downhill from here!
The Urban Dictionary offers one-of-a-kind products in its Coffee Mugs if you want to purchase something interesting. A bit off-center and not the norm. This is the place to be. Customer service is responsive to your query when asking a question. All Good.
Bought the mug, Holds up like a charm!! I was "Botello'd" by my wife so I think its fitting
Bought the mug. Holds up like a charm. I got "Botello'd" by my wife. Makes me feel nice.

its an alright mug. its moderate. mid. not the best. not the worst. pretty normal. if it was the weather it would be 50 degrees F. something so unexperiencing and experiencing at the same time. if it was on a number line, it would be in the center. i rate it a 5/10.
