Steps:

2.1.2 Synthesis of n-amyl nitrite
(24 g; 0.347 mol) NaNO₂ was dissolved in 94 mL water. When the temperature falls to 0 °C (or slightly below), a mixture of 6 mL of water, 8 mL of concentrated sulfuric acid and 27.5 mL (0.25 mol) of pentan-1-ol, which had previously been cooled to 0 °C, are slowly introduced from the separatory funnel to the mixture. The rate of the addition must be controlled so that the temperature can be maintained at ±1 °C. This addition takes 45-60 min. Afterwards, let the mixture stand for 1.5 h and then filter from the precipitated sodium sulphate. Separate the upper yellow pentyl nitrite layer (22.52 g; 76 %), wash it with a solution containing 0.25 g of sodium hydrogen carbonate and 3.0 g of sodium chloride in 12.5 mL of water, and lastly dry it with 3.0 g of magnesium sulfate.
