Hi guys, I managed to write the synthesis of n-butylamine to ChatGPT somehow, but I don't have much knowledge about chemistry and I have a few questions:
1- Does it really work?
2- Is the size of the balloon important that I used for the reaction?
here is the synthesis:
C) Synthesis of n-butylamine
CHEMICALS: Materials needed:
1- Add 4.4 g NaOH and 8.2 g NaCl to the flat-bottomed flask.
2- Add 50 mL distilled water and stir.
3- Fill the flask with 100 mL n-butanol and stir well.
4- Place the round-bottomed flask in the cooling bath.
5- Pour the NaOH/NaCl/water mixture into the round-bottomed flask.
6- Add the n-butanol from the flat-bottomed flask to the round-bottomed flask.
7- Heat slowly in the water bath and stir.
8- Continue heating and stirring for 1 hour.
9- Remove the round-bottomed flask from the cooling bath and let it cool to room temperature.
10- Carefully remove the upper layer and discard the bottom liquid layer.
11- Transfer the upper layer to the flat-bottomed flask and stir well.
12- To obtain pure n-butylamine, use a distillation apparatus to separate the mixture in the flat-bottomed flask into pure n-butylamine.
The distillation in step 12 can be carried out using the following steps:
1- Transfer the reaction mixture to a glass distillation column. Place a small amount of glass wool at the bottom of the column.
2- Place a heating source under the column and connect the column to a water-cooled condenser.
3- Begin heating the reaction mixture, and when the liquid begins to vaporize, lower the temperature of the heating source under the column to slow down the reaction.
4- The vaporized liquid will condense on the glass wool in the column and drip down back to the heating source under the column.
5- At the point where n-butylamine gas is formed, a higher temperature is required. Therefore, increase the temperature of the heating source under the column to allow the n-butylamine gas to condense at this point.
6- The condensed n-butylamine gas will be cooled by the condenser and turn back into liquid form.
7- The liquid n-butylamine will drip into a collection flask placed under the condenser.
8- Once the distillation process is complete, the n-butylamine should be collected from the collection flask and stored in another container.
