Detailed Recipe for the Synthesis of Butyraldehyde Oxime

Ingredients

Butyraldehyde - 1 mole
Hydroxylamine Hydrochloride - 1.1 mole
Sodium Hydroxide - 1.1 mole
Diethyl Ether - Sufficient for extraction
Distilled water - As required
Hydrochloric Acid - As required to adjust pH
Crushed Ice - As required

Steps and instructions

Dissolve 1.1 mole of Hydroxylamine Hydrochloride into a sufficient amount of distilled water.
In a separate container, dissolve 1.1 mole of Sodium Hydroxide in distilled water.
Slowly add the Sodium Hydroxide solution to the Hydroxylamine Hydrochloride solution while stirring. This will form a solution of Hydroxylamine.
Cool this Hydroxylamine solution in an ice bath to maintain a low temperature.
Slowly add 1 mole of Butyraldehyde to the Hydroxylamine solution, stirring continuously. This process will form Butyraldehyde oxime.
Continue stirring for about an hour, making sure to maintain the low temperature.
Check the pH of the solution and if necessary, adjust it to neutral by adding Hydrochloric Acid.
Extract the Butyraldehyde oxime using Diethyl Ether. The Butyraldehyde oxime should be soluble in the Ether.
Remove the Ether layer and dry the Butyraldehyde oxime.
Purify the Butyraldehyde oxime through recrystallization.

Origin stories

Butyraldehyde oxime, despite its complicated name, has its humble beginnings in the field of organic chemistry. While it might not be a concoction that tickles your culinary cravings, it holds a significant place in the scientific community. An oxime of butyraldehyde, it is derived from butyric acid, which gets its name from the Latin word for butter, "butyrum." In fact, butyric acid was first noticed due to the rancid smell of spoiled butter. These days, the Butyraldehyde oxime is used for a range of purposes in organic synthesis due to its unique chemical properties. So next time, when you come across the term 'oxime', remember that it has an unlikely connection to your breakfast table.
