  • 20 g of Sodium Bicarbonate
  • 50 ml of Distilled Water
  • 20 ml of Hydrochloric Acid (HCl)
  • Suitable apparatus for reflux
  • Separatory funnel
  • Rotary evaporator

Steps and instructions

  1. Set up the reflux apparatus and add 10 g of Succinic Anhydride and 10 g of Alkyl Amine into it.
  2. Add 500 ml of Dichloromethane (DCM) to the mixture in the reflux apparatus.
  3. Heat the mixture under reflux for 4 hours.
  4. Allow the mixture to cool down to room temperature.
  5. Transfer the mixture into the separatory funnel.
  6. Add 20 g of Sodium Bicarbonate to the separatory funnel and shake well to neutralize the mixture. Ensure to release the pressure regularly.
  7. Drain off the lower aqueous layer and retain the organic layer in the separatory funnel.
  8. Wash the organic layer with 50 ml of distilled water.
  9. Acidify the organic layer with 20 ml of Hydrochloric Acid (HCl), shaking well.
  10. Drain off the lower aqueous layer and retain the organic layer which contains the Alkyl Succinimide.
  11. Transfer the organic layer to a container and dry over anhydrous Sodium Sulfate.
  12. Filter off the Sodium Sulfate and evaporate the solvent using a rotary evaporator to obtain the Alkyl Succinimide.

Tools for making

  • Reflux apparatus - A setup consisting of a round-bottom flask, condenser, and heating source used for refluxing the reaction mixture.
  • Separatory funnel - A laboratory apparatus used for separating immiscible liquids based on their density difference.
  • Rotary evaporator - Also known as a rotovap, it is a device used to evaporate solvents efficiently under reduced pressure.

Recipe variations

  • Use different alkyl amines to generate different alkyl succinimides with varying properties.
  • Experiment with different solvents, such as toluene or ethyl acetate, instead of dichloromethane.
  • Try using different acid catalysts, like sulfuric acid or phosphoric acid, instead of hydrochloric acid.
  • Explore the use of different drying agents, such as magnesium sulfate or molecular sieves, instead of anhydrous sodium sulfate.
  • Adjust the reaction time and temperature to optimize the yield and selectivity of the desired alkyl succinimide.
  • Consider adding other reagents or additives to modify the chemical properties of the alkyl succinimide, such as antioxidants or surfactants.
  • Explore the use of alternative purification techniques, like column chromatography or recrystallization, to isolate the alkyl succinimide.
  • Investigate the possibility of conducting the reaction under different conditions, such as microwave-assisted or ultrasound-assisted synthesis.
  • Explore the use of renewable or environmentally friendly starting materials, such as bio-based succinic acid or plant-based alkyl amines.

Origin stories

Alkyl Succinimide isn't a food, but rather a chemical compound used as a detergent, dispersant or lubricant in various industries, like automotive and aviation. It might be interesting to note that it's actually derived from Succinic Anhydride, a substance that was originally obtained from amber, a fossilized tree resin highly prized in the past for its color and natural beauty. In fact, succinic comes from the Latin "succinum," meaning amber. So, in a way, when you're using a product that contains Alkyl Succinimide, you're benefiting from the magic of ancient forests!
