Comprehensive Guide to Nitroalkane Synthesis

Ingredients

  • 250 grams of ammonium sulfate
  • 500 ml of water
  • 200 ml of concentrated sulfuric acid
  • 400 grams of sodium nitrite
  • 500 ml of ice-cold water
  • 500 ml of 2-propanol (isopropyl alcohol)
  • Potassium hydroxide solution (10%)
  • 250 grams of ammonium chloride

Steps and instructions

  1. Dissolve 250 grams of ammonium sulfate in 500 ml of water.
  2. Slowly add 200 ml of concentrated sulfuric acid to the ammonium sulfate solution, stirring constantly.
  3. In a separate container, dissolve 400 grams of sodium nitrite in 500 ml of ice-cold water.
  4. Slowly add the sodium nitrite solution to the ammonium sulfate and sulfuric acid solution while stirring constantly.
  5. Allow the mixture to stand for 30 minutes.
  6. Add 500 ml of 2-propanol (isopropyl alcohol) to the mixture.
  7. Slowly add the potassium hydroxide solution to the mixture until it reaches a pH of 7, stirring constantly.
  8. Filter the mixture to remove any undissolved solids.
  9. Add 250 grams of ammonium chloride to the filtered mixture, stirring until it is fully dissolved.
  10. Distill the mixture to obtain the nitroalkane.

Tools for making

  • Glassware - Such as beakers, flasks, and graduated cylinders for mixing and measuring liquids.
  • Stirring rod - To mix the solutions thoroughly.
  • pH meter - To monitor and adjust the pH level of the mixture accurately.
  • Filtering apparatus - Such as filter paper and a funnel to separate solids from liquids.
  • Distillation apparatus - Including a distillation flask and condenser to separate and collect the nitroalkane.
  • Heat source - Such as a hot plate or Bunsen burner for heating and distilling the mixture.

Recipe variations

  • Using different nitrite salts such as potassium nitrite or calcium nitrite.
  • Exploring different alcohol solvents like ethanol or methanol.
  • Experimenting with different base solutions like sodium hydroxide or lithium hydroxide.
  • Trying different reaction temperatures or times to optimize the yield.
  • Using various organic substrates to synthesize a variety of nitroalkanes.

Origin stories

Nitroalkane synthesis, rather than being a food recipe, is a chemical process that was extensively studied and developed in the early 20th century. It's a vital part of organic chemistry, used for the production of various pharmaceuticals, pesticides, and other chemicals. Furthermore, nitroalkane compounds are also used as building blocks in the synthesis of more complex molecules. Interestingly, in 1932, a chemist named Henry Erying, used principles of this process to develop the Absolute Rate Theory or transition state theory, which revolutionized the understanding of chemical reaction rates and earned him a Nobel Prize nomination. Despite the complexity of the process, the synthesis of nitroalkanes can be carried out in a standard chemical laboratory with common reagents, demonstrating the elegance and versatility of organic chemistry.
