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
Exactly what I was hoping for! Great product
My coworkers see all the cups I order from you, and this one is already one of their faves
Just what I expected. Merchandise looked just like it did online. Showed my friends and even they loved the cup! Plan on ordering more merchandise from you guys. Thanks. KLDS
Astounding Mug. I found this Mug in a dark time, the time when I needed a mug the most. I went onto google.net and found this truly amazing piece of craftsmanship. Manny Heffley came out of my computer and started to gyrate, before hopping out completely and eating my asshole. It felts so good, I started shaking and moaning, rapidly convulsing on the floor. Manny Heffley slowly crawled into my, hiding in my womb in order to store his power for 12 months and evolve to the form of "Baby 2". Thank you, Urban Dictionary. This mug changed my life.
Looks great and quick delivery
very good quality, wasn’t broken or anything and was a good gag gift !
I gave it to her today. And she loved it said it was her to the T
The Printing wasn't very sharp, but it's good enough.
It was a surprise gift for someone and she absolutely loved it!
This was sent as a gift to my grandson, who lives in another state, so I never saw it. However I asked him as follows: "Just checking ... their request for a review shows an aquamarine mug ... it was supposed to be purple (eggplant, they called it). Was it purple?" Then he said: "It was purple! And thank you I love it haha Sent from my iPhone"
Shipment arrived quickly and in great condition. I know my custom mug will be a crowd pleaser when my girlfriend opens it up for Xmas.
Soaking is my favorite activity, glad I got a mug for it 😙
It DIDNT break :D
so happy you were able to put my unique word "Obergrossescheinehund" onto the new yellow mug. The yellow mug and black print make it easy for the words to be seen.
This is made by my friend i love it
Imagine not buying one of these. 🤢🗑🤡= non-buyer. Couldn't be me. 😎
It was the best thing I could have asked for
I mollywopped someone with it and it didn’t break. Nice
Product was as advertised and arrived pretty quickly too! The person loved their gift!
The "Pink Flamingo" colour with white text on a pink background is the best selection for this fine phrase mug. May I suggest you also correct the misspelling of "delightfully" in the default option for a timeless gift.
